We change the fuel filter of the fuel alone. How to replace the fuel filter with your own hands how to replace the fuel filter yourself

the main / miscellanea

Fuel, has a property to pollute, like any other automotive liquid. During the engine operation, various trash particles fall into it, as a result of which the car may threaten the unwanted breakage. In order to avoid expensive auto repair, you need to install fuel filter and periodically replace it.

The fuel filter (TF) has the ability to drain dust and dirt particles, and also prevents them from entering the engine fuel system. In the absence of this component in the device, malicious particles score channels and can output the entire fuel system.

Types of fuel systems

Gasoline filters have a different design, depending on the type fuel system The car to which they are installed. There are three types of fuel systems:

  • injector;
  • carburetor;
  • diesel.

Specific diesel filters It is that the type of such an engine is very vulnerable, so fuel for such systems should be carefully cleaned. In this case, the fuel passes 3 phases: in the gas tank, then coarse and thin cleaning. Also an important factor in a diesel fuel filter, is the ability to prevent moisture from entering the combustion chamber. If you consider all these circumstances, it becomes clear why the diesel filter is an order of magnitude more expensive than gasoline.

In turn, the design of the filters can be two types: unbearable and national team. If your car is installed in an indiscriminate gasoline filter, then if it is unreasonable, it will be necessary to fully replace the component. The prefab filters do not claim to be fully replaced, it will be enough to replace the filtrate itself.

Keep in mind: The correct filter is properly selected for your car model will save fuel, as well as increase its replacement interval.

For undime replacement Element of consequences for the fuel system can be very sad.

If you do not know where the fuel filter is located in your car and what is the frequency of its replacement, we advise you to refer to the instruction manual or to specialists a hundred. From the editors we can only add that on carburetor and diesel cars, Most. fuel filters are in the windscarette space. Gasoline filter In the injection car is located under the bottom (if the filter is unintended) or under the rear seat. In this situation, the fuel filter is usually located in the fuel pump and its shift is carried out by replacing the fuel pump. Injector filters are not subject to rust, as they consist of alloy aluminum and plastics.

Fuel filter replacement frequency

Information, data in this chapter will be useful to those motorists who do not know how many mileage kilometers should be replaced by the fuel filter. If you are in thought about the periodicity of the filter replacement and do not know how much your car will still go on it, then find the instruction manual or use the recommendations of the official dealer. In any case, this factor depends only on the state of your vehicle and its conditions.

The dyed of domestic road surfaces and not the highest quality of gasoline, allows you to make a discount at least 10 thousand kilometers from the figure specified in the instructions. In other words, if the manual indicates the frequency of filter replacement every 40 thousand km, then it is necessary to change it every 30 thousand km. In fact, Specialists a hundred recommend to replace fuel filters every 20-25 thousand km. Mileage, regardless of the manufacturer's instructions.

If the fuel filter is strongly contaminated, and this happens when the element is untimely replacing, the engine may not work at all. Evidence of the unusability of the component can be other signs of breakage, which make themselves to know through the large mileage of the car on a clogged fuel filter.

The main signs of the release of the fuel filter is

  • Intermittent engine operation;
  • During the movement, the car sometimes loses power;
  • While driving on small speed when you press a pedal, the car stalls, no matter how much you are "inserted" to the floor;
  • Incorrect speed switching (in the case of automatic transmission, the engine pulses incorrectly transfers to switching speeds and does not produce them in time);
  • Hurried fuel consumption.

These features accompany the fuel filter breakdown. If they do not let you know about yourself, then you will learn about the fault only when the car simply does not start at one far away.

How to change the fuel filter

Eternal questions "How to change the fuel filter?" And "How much can it serve?" Worried every motorist. There is no sufficient practice or at least the base of theoretical knowledge to replace the part, you can make a serious damage to the fuel system of your car. Installing the fuel filter is a fairly simple operation, so adhering to instructions in the step-by-step manual, you can independently cope with this task.

What will be required to replace the fuel filter?

In the event that the fuel filter is under the bottom of the car, you will have to use watching pit. Before dismantling the fuel filter, you should prepare:

  • New fuel filter;

Choose those that were produced by the manufacturer of your car or those that you advise you to install masters

  • Set of wrenches;
  • Cross and spatty screwdriver;
  • Soft fabric.

Instructions for replacing the fuel filter

This manual describes the procedure for replacing an indidimular fuel filter for any car. Based on the features of the vehicle design, some differences in the process may be present. If your auto fuel filter is in the fuel pump, first read the manufacturer's recommendations. Quite often, manufacturers advise changing the filter with a fuel pump.

So, you decided to dismantle the scored fuel filter:

  • First determine the location of the filter. As mentioned earlier, in carburetor and diesel cars The element is under the hood, under the bottom or in a tank with a fuel pump (in gasoline cars)
  • Regardless of the location of the fuel filter, the fuel pump fuse is removed and the time will wait until the car stalls. It is necessary in order to eliminate the pressure in the fuel system.
  • Next, it should be removed the minus battery terminal of the battery to prevent ignition during the fuel filter replacement procedure.

Dismantling of the old fuel filter

  • Then carefully inspect your fuel filter, and before removing, we determine the method of its fastener to the benzing (fasteners can be inlet or graduation). Depending on the design of the car, either latches or bolts are used. Be sure to memorize the fastening sequence so that you do not clean anything when installing a new fuel filter. You can even take a picture of the place of installation of the fuel filter on the mobile phone camera. Also do not forget about the location of pads and rubber bands.
  • After that, take the rag and wrap the fuel filter to it. The rag is needed in order not to stain your hands, since a small amount of gasoline is found out of the fuel filter. Using a wrench or cruciform screwdriver, disconnect the fuel filter from the mounting site. And then remove it.

Installation of a new fuel filter

  • The new cleansing filter is installed in the same position in which the old one was attached.

Pay attention to the arrow showing the direction of gasoline

  • Make sure the integrity of the nozzle and connect the gasoline. If it is damaged, then replace it;
  • Now we install the fuse of the fuel pump to the former place and connect the battery terminals;
  • Try to start the engine. The pressure was lowered in the fuel system, so the motor may not start from the first time. Turn on the ignition by 30 - 60 seconds., Then repeat the attempt.

Be extremely careful, do not forget about safety technician! If the fuel filter is replaced, then smoking indoors is strictly prohibited! Previous premises are also desirable.

We offer to see the following informative video on the fuel filter replacement

If the car engine has begun to work unstable (stuff, told, badly start), then there may be several reasons for this, one of them is the fuel filter failed. However, to make sure that this unit fell out of order, it is necessary to reliably determine the cause unstable work Engine. If the reason for the breakdown is in this detail, then the fuel filter replacement should be replaced by new aggregate, taking into account the features of different filter models. You can do this in the car service, or on your own. How to choose and independently replace the fuel filter, we will look below (see video "Replacing the fuel filter on the VAZ 2110, 2111, 2112" below).

When should I change the fuel filter?

Automotive experts advise to perform the replacement of fuel filters after 60,000 km of run, since it is by this time their sufficient clogging occurs. The car, of course, will be able to ride even long enough and on the clogged filter, however, in this case, the load on the fuel pump increases, the service life of which begins to decrease. In addition, the engine will start giving failures due to incorrect fuel supply. To reliably establish what the fuel filter broke (scored), it is necessary to do the following:

  • Dispersed cars at low speed;
  • Click as cracked on "gas".

In the event that the car engine started working with jerks or refuses to accelerate, then the cause of unstable work power aggregate It is in the filter, that is, the fuel filter replacement is inevitable.

How to choose a new fuel filter for the car?

Key options. The selection of the fuel filter should be performed, given the following key parameters:

  • Taking into account the size of the filtering level: it depends on it, which, largest particles should be filtered. If you select a low-filter filter, then large particles will penetrate the fuel and, in the sooner, the engine will be displayed.
  • Consider the area of \u200b\u200bthe filtration element, the clogging speed will depend on it: the greater the area, the longer the filter is served, and vice versa;
  • The presence or absence of a rubber seal covering the filter inlet: filters without a sealing is more complicated.

Cleaning level. It is also necessary to distinguish fuel filters by cleaning level so that the element replaces is performed correctly. So, there are carburetor, injection and diesel fuel filters. Each type of engine is the corresponding fuel filter.

  • For carburetor systems, the cleaning level is ranging from 15 to 20 microns. Everything that is smaller will fall into the fuel system, however, no harm to the engine will be represented;
  • For injection systems, the cleaning level is ranging from 5 to 10 microns.
  • For diesel systems, the cleaning level is within the limits of less than 5 microns. In this case, not only particles in fuel are filtered, but also water.

Of course, buying a new automotive fuel filter, you need to know the brand of the old filter, as well as the time of its release. As for the replacement of the filter to a similar one, but another brand, then here you need to carefully examine the possibility of this operation in the instruction manual.

How to change the fuel filter yourself?

Before starting work, it is necessary.

The direct replacement of the fuel filter on the car begins with the definition of its location. The most common version of its location is under the hood, on top of the engine (almost all diesel engines).

W. gasoline engines The fuel filter is located in the immediate vicinity of the fuel pump.

1. You need to start the engine engine.

2. Immediately after the filter is found, it is necessary to dismantle its fuse, and wait until the engine itself is to fall so that the pressure fell, and the fuel does not start pour out.

3. Then remove the terminal from the battery with the "-" sign (in order to prevent fire).

4. After that, disassemble the scheme of how the dismantled filter is mounted in the fuel engineering system. Remember the sequence of the location of each of the attachments, as well as the washers and gaskets.

5. Removing the unit from the bracket, and wrapped it with a rag, you need to pull it carefully (wrapped rack will absorb oil, when leaking it).

7. Using new fasteners, connect the filter to the fuel engineering system.

8. On this, the replacement of the fuel filter on new element Completed. It remains only to put a fuse, taken out at the very beginning of work, at its former place.

9. Connect the back negative terminal and start the engine.

Note that an attempt to start the motor from the first time is usually not possible, since pressure should be recovered during dismantling.

Each motorist is soon or later faced with the moment when the car fuel filter is replaced. The fuel filter is a part that is capable of cleaning gasoline before it gets into the engine cylinders. The cleaner of gasoline will fall inside, the longer the engine will be corrected. Since clean gasoline or diesel fuel or diesel fuel is not always poured at refueling, everything can be in it, from sand to rust. The filter copes with similar elements, and they settled on it. It is impossible to ride with a contaminated filter, since over time its throughput drops, power drops or the machine does not start. Then the question arises how to change the fuel filter.

How often do you need to replace

The recommended fuel filter replacement period is the expiration of 30,000 - 50,000 kilometers of driving, as it is about so enough of its full work. This is a kind of regulation. Also the duration of the period depends on filling stations and travel manners. Usually, if the engine has started taking or stroke, it can be perceived as a signal that it is time to change the filter elements. It also corresponds to the drop in power, increased flow Fuel and if the car does not start.

It is impossible to give a car to work on a clogged fuel filter, as in the bad case you have to study not only how to change the fuel filter, but also make a flushing of the motor, which will cost big money. It is also important to understand that the declared mileage before replacing the filter is indicated by manufacturers who have better than the purity of the roads. In our realities, to a question after how much to change the fuel filter, experts believe that the digit for replacement can be 20 - 25,000 km, and for diesel filters about 10,000. It is important to know how to replace the fuel filter to work yourself.

Features of filters and their location

Purification of gasoline has two or more purification. The first degree of large particles are falling, which falls with fuel to the tank. Small particles are already there on a fine cleaning filter, and they are located directly in the highway between the tank and the engine. The location in every car is different, but most often it is located directly in the fuel tank itself.

The gasoline filter has the difference in its design. They are installed on vehicles depending on fuel injection systems. You can share the system on 3 types:

  • Injector.;
  • Diesel.

Filters are divided into:

  • The team - only the filtering element changes;
  • Not collapsible - requires full replacement Total fuel filter.

Not collapsible filter

You can find out the fuel filter location for a specific model in the instruction manual. Mostly, diesel filters Located under the hood. For an injection car, as a rule, when the filter is not collapsible, you need to search under the bottom of the car or the rear seat. If the collapsible, then in the fuel pump and all work is to replace the mesh on the fuel pump.

Precautions

Since any spark can provoke fire, it is better to comply with the elementary safety technique. It is impossible to be near the filter with a cigarette. It is always better to have a fire extinguisher next to you. It is better to perform everything in a well-ventilated room, or on the street. When the fuel filter replacement is finished, you need to wash your hands from fuel residues, with soap and water. It is better to use glasses to protect your eyes.

Procedure for work

To replace the fuel filter with your own hands, it is successful, you will need to have a set of keys. Specifically, you need keys under nuts 10, 17, 19. Before starting work, you need to disconnect the mass from the car so that the short circuit does not occur. Next, the key to 17 or 19 clamp the working filter and the key on 10 is unscrewed the nozzle. It is important that the fuel does not fall into the organ of vision. All fuel residues merge into the plastic container. 10 The key needs to unscrew the fitting, which is at the fuel pump from the other edge. To do this, the clamp is a little weakened, after which you can start to unscrew it. You need to know which way to unscrew it, which is written in the instructions for the details. Most often, the direction of the fuel movement is indicated by an indicator that is applied to the case. When the dismantling is completed, you can begin the installation of a new fuel filter of gasoline. Installation is performed in the same order, only on the contrary. It will be better for the filter installing a new locking clamp. This will increase the service life of the part.

In order not to donate the fuel, it will be better to lower the pressure. To do this, click on the ramp spool. As an option to remove the fuse when the car started and leave the motor in working condition, until it stops.

After the installation is completed, you need to check how the new device behaves when the engine is started. It should be verified that there are no leaks of gasoline. In the event that such are discovered, then the problem is probably in rubber rings, you need to replace them. It is better to do it immediately, as it will later have to return to this. On this, the filter replacement work can be considered completed.

Replacing diesel filter

For work requires:

  • Hand type vacuum pump;
  • Capacity for fuel;
  • Fuel filter cartridge;
  • Sealing ring on the filter cover;
  • Water containers.

In general, the replacement of the fuel filter on the diesel engine occurs according to the similar scenario, but with some nuances:

  • To start, turn off the ignition in the car;
  • You need to unscrew the cartridge from below, after setting the container under it. After completing the collection of fuel, it is necessary to wipe the cartridge well from fuel residues;
  • To remove the filter shell, you need to unscrew the bolts and remove the fasteners;
  • Fuel hoses are disconnected;
  • The cabinet fastening filter is removed.

Before installing the cartridge you need to remove water that is present inside the filter. Here and need to have vacuum pump. Next, the tube is inserted, which will suck directly to the filter housing. After that, you need to make sure that the filter is clean, and then you can already insert the cartridge.

The housing is closed with a lid, which sits on a new sealing ring. The ignition is turned on for two seconds, but the engine should not start. It is necessary to activate the pump that pumps the fuel to fill the combustible filter and removing the air, which could be formed in the fuel system, in the case of a replaced filter. In the case of fuel formation on parts from rubber, you need to wipe it. On this fuel filter replacement diesel engine It is considered completed.

Conclusion

So that there are no problems with the fuel system, it is necessary to observe the frequency of replacing the fuel filter, then the probability of the engine breakdown will be excluded. If the machine is badly started, the filter is the first thing to pay attention to when it has not changed for a long time. An experienced driver can always understand when changing the fuel filter.

If you have any questions - leave them in the comments under the article. We or our visitors will gladly respond to them

The article is very detailed with step-by-step actions and photographs described the procedure for replacing the main fuel filter. Also given advice and practical recommendations safety.


The fuel filter was developed to clean the fuel before it fell into the combustion chamber. When the driver presses gas, the filter controls the feed, both fuel and air into the engine. And the composition of fuel and air should be as high quality as possible. In order for the process when mixing, ignition and combustion, it is excellent, you need to be very clean. That's what the fuel filter is used.

When should I replace the fuel filter?

There is no exact period when replacing the fuel filter. Manufacturers recommend replacing it every 60-90 thousand kilometers. But the replacement can occur both faster and later. Change the filter will have to have ineffective work. This can be defined if the car at high speed moves jerks, told, if we touch, the car stalls and start with the stretch. Also, with a clogged filter, the car may not start at all.

Replacement can be performed using the manufacturer's recommendations. After all, the regular replacement of the fuel filter does not damage your engine, but will only be better. But if it is not for you to pocket, then the replacement of the filter, when using high-quality fuel, can be made every two years (it is worth considering the behavior of the machine). But since the quality of fuel is not from the highest ratings, then better replacement "Cleaner" to spend more often. The fuel filter prevents the engine breakdown. Therefore, it's easier to change in a timely manner, and then the engine is then. It should be considered when you choose a filter, on its quality. Branded fuel filters will not clog the nozzles and the carburetor, will serve longer. Most machines have, which protects against smaller garbage and from moisture that has fallen into fuel. The replacement of a fine fuel filter is to be carried out regularly to avoid clogging, which will lead to a breakdown of nozzles.

Security and tools

Also conducting the fuel filter replacement you need to think about the safety technique. Optimal option For his replacement is the street. Because gases that are distinguished from fuel, much harder air, and can accumulate indoors and provoke a fire. It is better to perform work in protective gloves and glasses so that gasoline does not hit the skin of the hands and eyes.

You can replace in the service center, but you can try to do it yourself. To do this, you will need elementary tools: pliers, wrench, screwdriver. For some machines, you will need a ratchet and key of the end. If the one is very difficult to get to the one, then the lantern and jack will not hurt.

The procedure for replacing the fuel filter:

1. First of all, you need to disconnect the negative terminal from the battery. This is done to avoid the fire of fuel vapor.

2. Then it is necessary that the pressure in the power system is reduced. Without reducing it, fuel will overcome everywhere. Therefore, to put the car on the brake parking and the gearbox lever is placed on the neutral.


3. on rear seat Remove the pillow, unscrew the bolts and remove the cover.

4. You will see a block with wires there, it is necessary to disconnect it by clicking on the plastics latch.

5. Then start the car and wait until it stalls due to the lack of fuel.

6. Include for three seconds starter and then disconnect the fuel line.


8. On both sides of the fuel purifier to unscrew (weaken) a little nut on the tips of the hoses.

9. Also a little weaken the fastening of the cleaner holder.


10. Fully unscrew the nuts on the hose tips, given that the fuel will be slightly. So that it practically does not flow, the filter can be wrapped with some rag.

11. Fully release the cleaner from the holder and take it out.


12. On the lugs of the hoses, remove and check the sealing rings. If they are damaged, they should be replaced.

13. New filter Install B reverse order, given that he should be installed so that the shooter on it looks in the one direction where the flow of gasoline is.

14. To the wiring harness to attach the block of wires of the fuel pump and the terminal to the battery. Install seats.

After all, you need to start the car, but not to be afraid if the car could not get the first time. It will not start due to the fact that the pressure was reduced. You need to start the car several times so that the pressure comes to normal. After that, the car must start.

Changing fuel filters in a timely manner, you will extend your life to your engine, and it will serve you trouble-free for many years. And the car's trip will be comfortable.

Many car enthusiasts may think that the fuel filter in the car's device is not a particularly important element. But it is worth noting that the condition of the entire fuel system of the vehicle can significantly influence driving performanceAnd in some cases - to cause breakdowns. Therefore, it is worth carefully monitoring the state of those elements that provide cleanliness of fuel.

It is the state of the fuel system and its performance, may affect the reduction dynamic characteristics car. This happens unnoticed and for a long time. But the moment comes when the car owner notices that earlier, his favorite car was righter and faster. This is the first sign that it is worth checking the condition of the filter, and remember when it was, he changed for the last time.

Why fuel filters fail

The answer to this question is very simple. By title of this element, you can guess what it serves to clean the fuel from various types of pollution. All filtered dirt and an extra mixture, settles on the filter element, and gradually scores it. This leads to a decrease in the filter bandwidth, which leads to a violation of normal fuel supply.

It is worth noting that some car manufacturers claim the possibility of working the fuel filter on their car, the entire service life of the vehicle. Perhaps this statement takes place, but most likely, this result can be achieved only in laboratory and sterile conditions. Especially, taking into account the quality of fuel selling on the territory of the former USSR.

How often do you need to change the fuel filter

If we take into account the recommendations of automakers, and many years of experience in multiple car owners, then you can withdraw the average number in the periodicity of the replacement, about 30,000 km. It is such a frequency that is considered the most effective, not carrying large service costs, and maintaining normal fuel supply.

Naturally, these numbers are an exemplary and averaged period for replacing the filter. Which can vary in wide ranges, depending on the set of external factors. Therefore, it is worth getting used to your car, and its operating conditions, and then develop an approximate periodicity of replacement.

Signs of the scored fuel filter

It is worth noting that these features may indicate completely different reasons. But if you remember that the fuel filter has changed a long time, then first of all, it is worth changing it, and only then continue the diagnosis of the car if the problem has not disappeared.

Basically, the sign is one, and it is manifested in any problems when an insufficient fuel is received into the motor. To be more accurate, the engine significantly loses its power, can time to trim, badly start on the cold or dips on large revolutions appear.

Replacing the fuel filter on the diesel

Diesel filtering has its own characteristics that can be described by a separate article. But you can select several basic moments, and summarize the results of replacing the fuel filter on diesel vehicles.

In some cars, the filtration system of diesel fuel can have three phases of purification. To be more accurate, then fuel diesel system In its design, has a separator, filter rough Cleaning and fine cleaning filter.

Each of the elements performs its functions, and can be set by separate components or are collected in one case. Separator produces water separation from diesel fuel and internal design Looks like a household siphon with a seventery for water. Coarse cleaning filter detains fuel pollution having large fractions. Accordingly, the fine cleaning filter produces the final filtering stage, and the output gives the perfectly clean fuel, which enters the engine through the nozzles.

It is precisely a filter of fine cleaning. It is necessary to change most often, and the replacement interval may have only 10,000 km.

Features of winter operation of diesel engine

Again, there are several nuances associated with the principle of cleaning diesel fuel. First of all, in the separator, a certain amount of water accumulates during operation. Which has a freeze property at negative temperatures, and interfere with the bandwidth of the element. Therefore, it may be necessary to replace this element.

Also, there is a danger that at the gas station, in fuel tank A summer version of diesel fuel will be flooded. Which at low temperatures highlights paraffin, clogging fuel filters. Therefore, it is best to have a spare filter in the trunk (just in case), and refueling on proven filling stations, and only diesel fuel With winter additives, at the appropriate season.

Output

The frequency of replacing the fuel filter is an individual question depending on the set of factors that includes a car model, the quality of the filter, the quality of fuel, the vehicle of the car operation and many more different factors that can affect the interval in a large or smaller side.



Therefore, it is necessary to rely on our own feelings from the behavior of the car, and on your own experience, or the experience of other car owners of this model in your region. As practice shows, car owners change fuel filters from 10 to 80 thousand kilometers. Agree, the rank is very large, and it is impossible to focus on it. Therefore, we independently produce your interval, and stick it. Thus, you will help your car work much longer, and more stable.
