Until a certain point, some car owners have no idea about such a fuel system cleaning element as a fuel filter and, naturally, do not know how to change it. According to the manufacturer, the gas filter should be changed every 30 thousand km. vehicle mileage, provided good fuel is available. Unfortunately, the quality of products at domestic gas stations does not meet all quality standards, as a result of which motorists often encounter unpleasant situations when engine failures and jerks begin to manifest themselves, first at high speeds, and then at low speeds. It happens that such symptoms do not occur at all, but it may happen that one day, far from perfect, the car will not start at all, since the clogged engine will fail. To avoid such undesirable consequences and repair the most expensive part of the car, experts advise changing the fuel filter every 15-20 thousand km. mileage
In this article we will look at replacing the fuel filter on a VAZ 2114 produced in 2007, which came to us with the problem of unstable idle and small dips while the car was moving when gaining speed. You will learn how to replace the fuel filter in a VAZ 2114 yourself, in what cases it needs to be replaced, and which brand of cleaning element is best to choose.
Signs of a clogged fuel filter
Before you start replacing the fuel filter yourself, you must make sure that the cause of the engine malfunction lies precisely in a clogged fuel filter. During operation, the filter “accordion” becomes clogged with various debris, and the throughput of the filter decreases sharply, causing interruptions in engine operation. There are a number of symptoms by which you can determine that the cause of the problem is due to the unsuitability of the fuel filter:
- fuel consumption increases;
- the car stalls at idle;
- when the speed increases, engine dips and jerks occur;
- Engine power decreases, especially when going uphill;
- the engine starts every once in a while;
- the car brakes without pressing the pedal
There are many signs of a clogged fuel filter and they are all varied. In addition, you should pay close attention to them, since all these troubles do not clearly indicate a failed fuel filter. In addition, they may indicate malfunctions of any parts of the control system: crankshaft position sensors, electronic control unit, detonation, mass air flow, throttle position, spark plugs, idle air control, wiring.
To be sure that it is the fuel filter that is faulty, use the following method: connect the pressure gauge to the nipple located on the fuel injector frame; Start the engine and measure the fuel pressure. If the pressure gauge data is lower than the regulated pressure in the car’s operating instructions, then you can be sure that the cause of the accident lies precisely in a clogged filter element.
What is a VAZ 2114 fuel filter?
The VAZ 2114 fuel purification system consists of two filters - a coarse fuel filter and a fine fuel filter. The coarse fuel filter is located in the fuel tank and is a mesh that prevents large particles of dirt, water, etc. from entering the fuel system. We will consider replacing the coarse fuel filter in more detail in another article.
The VAZ 2114 fine fuel filter is a metal glass with a filter element made of special paper. The VAZ 2114 fuel filter has an inlet and an outlet.
On VAZ 2114 cars of an earlier production year, filters with threaded fastening to the fuel line are installed. But newer VAZ 2114 cars are equipped with fuel filters with a fitting. This is the so-called Euro mount, which allows you to quickly replace the fuel filter.
A fuel filter with a threaded fastening and a fitting fitting is shown in the figure below:
Fuel filter for VAZ 2114
Before you start directly replacing the old filter with a new one, you should go to a car store and purchase a good cleaning element for your VAZ 2114.
As you know, VAZ 2114 cars are equipped with injection power units, the volume of which is 1.5 and 1.6 liters. Injection engines require more thorough cleaning of the incoming fuel, unlike carburetor engines. Therefore, the VAZ 2114 fuel filter must have a throughput capacity of 5-7 microns and withstand an operating pressure of 3-5 bar.
Fuel filters on the VAZ 2114 differ in the methods of fastening the fuel pipes: in cars with a volume of 1.5 liters, a hexagonal mount is used; For models with a volume of 1.6 liters, spring fixation (latches) is used.
The cost of fuel filters depends on the quality of the product itself and the manufacturer. Each car owner decides for himself: whether to overpay for a well-advertised brand or purchase a high-quality filter from a little-known company at an average price. The only thing is that you should not purchase products of obviously dubious quality.
The approximate price of a fuel filter for a VAZ 2114 car is 150-600 rubles.
For our VAZ 2114 we purchased a fuel filter - MANN - WK 31/2. Quite a good example.
How to replace the fuel filter on a VAZ 2114
Location
In order for its replacement on a VAZ 2114 to be successful, you first need to find the filter itself. You need to look for it under the car, it is located immediately behind the fuel tank.
How to choose
No such gas filter has yet been invented in the world that would purify fuel from impurities by 100%. Now there are those that can delay the ingress of dirt by 50% -95%. And they all work on the principle that the larger the dirt particles, the easier it is to retain it. They are also conventionally divided into average and nominal screening fineness. It is better to choose it nominal (fine fuel purification). This is capable of retaining pollution by 95%, and particles from 50 microns or more.

Safety precautions when working with the fuel system
Do not neglect safety rules, especially when working with flammable materials. When replacing the fuel filter, gasoline may spill, so work should be done in a well-ventilated area. So, before starting work:
- De-energize the vehicle by removing the terminals from the battery;
- Do not perform the procedure near fire sources and do not smoke;
- Keep a fire extinguisher nearby;
- If gasoline comes into contact with your skin, wash it immediately with soap and water.
How much does it cost to replace a VAZ 2114 fuel filter?
The cost of replacing a VAZ 2114 fuel filter at a specialized service will cost the car owner from 250 to 500 rubles. The cost of the VAZ 2114 fuel filter itself varies from 110 to 400 rubles. Thus, the cost of replacing a VAZ 2114 fuel filter can be several times more expensive than the cost of the fuel filter itself. Agree, if you can save this money, then why pay more? Moreover, the procedure for replacing the fuel filter itself will take only 10-20 minutes.
Relieving pressure in the fuel system
Before any operations concerning the fuel system, it is necessary to relieve the pressure in the fuel line. To do this, put the vehicle on the handbrake and turn on neutral; remove or move back the rear seat; open the hatch located under the seat on the bottom of the car; turn off the power to the fuel line by disconnecting the connector. Next, we start the engine and wait a while until all the gasoline in the engine is used up and it stalls. After this, we try to start the car again to make sure that the fuel pressure has disappeared.
There is a second way to release fuel pressure. To do this, you need to remove the negative cable from the battery and remove fuse F3 in the mounting block, which is responsible for powering the fuel pump. Next, we also bleed off all the fuel in the engine by starting it. After releasing the pressure, install the fuse in its original place.
Instructions for replacing the VAZ 2114 fuel filter.
1. We stock up on desire, take all the necessary tools, and change into work clothes.
2. We drive the car into a pit or overpass. Or we simply lift the rear of the car as high as possible with a jack. Be sure to use the handbrake, speed and wheel chocks.
3. Disconnect the negative terminal of the battery (make this a rule when working with gasoline).
4. Relieve pressure on the fuel rail under the hood:
This is necessary so that when removing the fuel filter, gasoline does not flow into your hands. At this point you will need a container to collect fuel. This completes the preparatory work for replacing the fuel filter. Let's move on to the procedure for replacing the VAZ 2114 fuel filter.
5. If the filter has a threaded fastening, then loosen the thread using open-end wrenches 17 and 19. If the filter has a fitting, then simply bend the lock and move it to the side. Be prepared for some more gasoline to leak out of the fuel filter. After the fuel hoses are unscrewed, use a 10 mm wrench to loosen the clamp that secures the fuel filter to the body. And pull the filter out to the side.
6. Install a new fuel filter in place of the old one. It is important to install the VAZ 2114 fuel filter correctly, since the inlet and outlet of the filter are different. On all filters, the direction of fuel supply is indicated by an arrow.
7. Change the rubber o-rings. This is done very simply, but it is better to use lubricant. Solidol or Litol will do. It is necessary to use lubricant when replacing the VAZ 2114 fuel filter in order not to damage the rings.
When the rings are installed, we assemble everything in the reverse order.
After the VAZ 2114 fuel filter has been replaced, you need to pump fuel into the system. To do this, turn the ignition key several times, but do not start the engine. 2-3 times is enough. Practice shows that during this time the pump completely pumps the entire fuel system.
That's all. Now you know how to change the fuel filter of a VAZ 2114 with your own hands. In addition, this instruction is suitable not only for VAZ 2114 cars, but also for other front-wheel drive VAZ cars with an injection engine. Do you agree that this is not as difficult as it seemed before? You can buy the fuel filter itself on our website at any time, and also receive free advice on selection and replacement. Just call 8(3843)60-00-42 or 8-923-464-0042 . Thank you for your attention. Until next time.
Cleaning the fuel is necessary for the normal operation of a car engine and increasing its service life. The engine must receive fuel purified from various impurities and contaminants. For this purpose, it is customary to install fuel filters. How to work with them on VAZ 2109 and 99, 2114 and 2115 will be discussed below.
Removing the old fuel filter
To replace the filter, we need a lift or inspection pit. The fuel filter is located on the bottom of the car behind the gas tank, in front of the exhaust pipe. It is mounted in the form of a cartridge on the fuel line of the VAZ 2114.
The process of removing the old filter varies significantly for cars with different engine sizes.
Our VAZ has a 1.5 liter power plant, so we will remove the filter as follows:
- First of all, we loosen the bolt that tightens the fuel filter clamp, using keys “10” and “13”.
- Next, lubricate the gas filter nuts with WD-40 aerosol preparation, after which, using open-end wrenches “19” and “17”, unscrew the nuts securing the VAZ 2114 fuel filter.
Please note: unscrew the nuts carefully, being careful not to damage the fuel line hoses.
- In the same way, unscrew the nuts on the other side of the gas filter. Be careful that suddenly spilled gasoline does not get into your eyes and spill. To avoid this, wear construction glasses and place a container to collect gasoline.
- Carefully disconnect the fuel line tubes from the base.
- Next, remove the filter.
If you are the owner of a VAZ 2114 with a 1.6 liter engine, then your task is simplified. You just need to press the spring clamps of the fuel line and very carefully remove the hoses.
Replacing the VAZ fuel filter
Details Category: Repair Published 10/01/2014
The fuel filter is designed to clean fuel before it is supplied to the engine power system.
The fuel filter replacement interval is usually 30 thousand km, however, when using fuel of questionable quality, it is better to shorten this interval.
For cars with an injection engine, the fuel filter is most often located under the car, near the gas tank. Replacing it is more difficult than with a carburetor: access is required from below the car, and you must first relieve the pressure in the fuel system. Let's look at how to replace the fuel filter yourself, using the Lada Kalina car as an example. To replace the VAZ fuel filter, it is advisable to place the car on a lift or overpass.
The fuel in the fuel system is under pressure, so it must be relieved before replacing the filter. To do this you can use this method:
- remove the fuel pump fuse (on Kalina it is located in a niche near the gearshift lever)
- start the engine and wait until it stalls
- We turn on the engine with the starter a couple of times so that it burns out the remaining fuel.
Turn off the ignition and go under the car. Don't forget to take a new filter with you.
On the Lada Kalina, the fuel filter is located to the right of the fuel tank, it is mounted on a bracket.
In order to remove the old filter, you need to disconnect the inlet and outlet pipes on both sides of the filter. To do this, carefully squeeze the plastic clips and pull the pipe, removing it from the filter.
Attention! When the pipe is disconnected, residual gasoline may spill out of the fuel filter, so immediately prepare a rag or some container, and also protect your eyes!
Having disconnected both pipes, remove the old filter from the bracket.
We install a new filter instead.
Attention! The filter must be installed so that the arrow on its body is located in the direction of fuel flow (that is, looking forward).
Having installed the filter, we attach both pipes to it until a characteristic click is heard.
Now you can replace the fuel pump fuse and start the engine, after which you need to make sure that the connections are tight and there are no fuel leaks.
Installation of a new fuel filter on a VAZ 2114
Before installing a new filter, do not forget to change the O-rings on the fuel pipes.
If gasoline gets on the rubber parts or the filter itself, wipe these components dry. Otherwise, they will not serve you for long.
The gas filter is installed in the reverse order of its removal. Pay attention to the direction of the fuel filter. There is an arrow on its body indicating in which direction the flow of gasoline is moving. If your car is equipped with a 1.5 liter engine, then the arrow shows the direction from the right to the left side. If the car has a 1.6-liter engine displacement, then, on the contrary, the flow of gasoline will be directed from left to right.
After installing a new filter, some time must pass before the cleaning element is filled with gasoline and displaces all the air. After this, proceed to check the tightness of the connections. Start the engine for 5-6 seconds and inspect it for any gasoline leaks. If you find fuel leaks, try fitting the fuel pipes onto the filter more tightly.
Why do you need to change the VAZ 2114 fuel filter?
Due to a dirty VAZ 2114 fuel filter, the following malfunctions may occur: 1. Unstable idle speed (in other words, “floating” idle speed, or they also say that the engine “troits”); 2. Difficulty starting the engine. If the VAZ 2114 fuel filter is clogged, then starting the car will be quite difficult due to a lack of gasoline; 3. The engine does not develop full power. This is another malfunction in which the first step is to replace the fuel filter; 4. Increased fuel consumption. No matter how paradoxical it may seem, it is precisely because of a clogged fuel filter in the VAZ 2114 that fuel consumption may increase.

To achieve this, I experience car breakdowns less often, I have to regularly maintain the vehicle and often make changes to worn parts on a personal computer. This is especially true for fuel system related parts, since problems with the fuel system directly affect the engine.
The fuel filter is one of the key parts of this system, its function is to filter out dirt, rust and other solid impurities contained in the fuel using special filter paper. Thanks to the filter, purified gas enters the engine.
Any car owner needs a change, so we will carefully consider the following questions: how to replace the fuel filter on a VAZ 2114 without outside help, where you need to change, which filter to choose for this.
Signs of a clogged fuel filter
When using filter paper, the gasoline filter elements become clogged and its throughput decreases, which leads to an immediate interruption of engine operation. Of course, a number of such signs point to the following situation:
- fuel consumption increases sharply;
- the car often stops idling;
- when the speed increases, malfunctions occur during engine operation;
- there is a problem with starting the engine;
- when the engine is running, its power is miniature;
- at one time the car brakes without pressing the pedal;
- the car locks when climbing a mountain.
There are many signs that your fuel filter is clogged, and they vary widely. Today, caution should be exercised as such features do not indicate that the filter is broken. They should also indicate malfunction of parts of the engine management system metering: electrical control unit, crankshaft position sensors (DPKV), mass air flow (DMRV), throttle position (TPS), knock (DD), as well as spark plugs, wiring or idle control. To ensure that the fuel filter is the cause of poor performance, of course, use the following method. Connect the pressure gauge to the nipple located on the fuel injector frame; Enter and measure fuel pressure. If the characteristics of the pressure gauge are lower than expected in the technical documentation for the car, then the filter becomes clogged with problems.

Where is the fuel filter of a VAZ 2114 car located?
The fuel filter is mounted in the form of a cartridge in the fuel line of the VAZ 2114 car. It is located below the barrel, flying, as it is called, in a ditch, useful for inspection and replacement. If you can't find where the fuel filter is in your car, take a close look at the visible part of the fuel that allows for accounting (software). it is located directly behind the gas tank, in front of the exhaust pipe.

What tools are needed to replace a gasoline filter?
For proper independent operation, the gasoline filter
For a VAZ 2114 car you will need:
- new filter to suit the design;
- Rings for pipelines;
- wrenches sizes 10, 17 and 19;
- two tanks: one to collect gasoline (make sure it is clean and dry), the other to drain water.
Replacing safety rules
Replacing the fuel filter may result in a gasoline spill. Therefore, work should be carried out in a well-ventilated area or, preferably, outdoors.
Since automobile fuel is a flammable combustible material, the following safety rules must be observed:
- Don't forget to turn off the vehicle's power supply by disconnecting the terminals from the battery.
- Do not work near open flames; I do not smoke.
- Be careful with fire extinguishers: fire extinguisher, sand or water.
- Replacement carries the risk of gasoline getting on the skin and mucous membranes, so they must also be protected.
- Place the rags and rags that are used to wipe up gasoline separately.
Relieve pressure in the fuel system
Before performing any repairs on the fuel system, the fuel pressure must be relieved. To do this, put the car on the parking brake and put the transmission in neutral; remove or move the rear row of seats; open the hatch located below the seat; Disconnect the fuel pump by unplugging the connector. Then you need to start the car and wait a few minutes until all the gasoline pumped into the engine runs out and the car itself dies. After this, you should start the car several times to make sure there is no fuel pressure.
If you cannot complete these steps, then you can relieve the fuel system in another way. To do this, remove the negative terminal from the battery; Fuse F3 must be removed in the VAZ 2114 mounting block, which is responsible for powering the fuel pump. The fuel in the engine must also be activated. After reducing the pressure, do not forget to replace the fuse.
Remove the filter you are using
The process of removing an old clogged VAZ 2114 car filter differs significantly for models with different engine sizes.
If the machine has a 1.5 liter power unit, the filter is removed as follows:
- Thoroughly lubricate the fasteners for easy removal.
- Remove the inlet gas fittings. Use keys 17 and 19: hold key 19 to filter
, do not scroll; wrench 17 unscrews the fittings. Drain the remaining gas from this section of the pipeline into a previously prepared tank. - Do the same to remove the exhaust pipe fitting on the opposite side of the filter; Drain off any remaining gasoline.
- Carefully disconnect the base of the fuel line.
- Unscrew the clamp to which it is attached using an open key 10.
- Carefully remove the filter.

Installing a new filter on a VAZ 2114 car
Before installing a new one. Gas pipeline seals have been replaced. If gasoline falls on the filter, especially on its rubber parts, wipe them dry. Otherwise, gasoline will significantly reduce the service life of these parts.
The gasoline filter is installed in the reverse order before removing it. Be sure to pay attention to the direction of the filter: there is an arrow on its body indicating the direction of gasoline flow. If your car is equipped with a 1.5-liter engine, the arrow should point right to left; with 1.6 liter engine. vice versa, from left to right.
After installation, wait until the new filter is filled with gasoline and all the air has been forced out of it. You can then proceed to test the connection for leaks. To do this, run the engine for a few seconds and inspect it for leaks. If you find a fuel leak, try pushing the fuel line fittings towards the filter.
How much does a fuel filter cost for VAZ 2114
The cost of gasoline filters depends on both the quality of the product and the manufacturer. Every car owner must decide whether to overpay for a well-known brand or buy a quality filter from an inexpensive manufacturer at an average price. Do not buy products of obviously questionable quality.
The estimated cost of a VAZ 2114 is 150-600 rubles.
Fuel filter replacement frequency
When to change the VAZ 2114 fuel filter is a controversial question. On the one hand, the manufacturer recommends replacing it every 30 thousand kilometers. But, on the other hand, the quality of gasoline at gas stations leaves much to be desired; a large amount of impurities significantly reduces the service life of the filter by about 10 thousand kilometers.
