Lifehack Lada Vesta: fuel filter system analysis

The presence of debris in gasoline can lead to clogging of fuel system elements and cause unstable operation of the power unit. To prevent such a situation, the design of the Lada Vesta car provides special coarse and fine fuel filters. When using a vehicle, the filters become clogged with debris. Because of this, the throughput of the fuel module decreases, and additional load is placed on the fuel pump. The way out of the situation is to replace or clean consumables. Changing the fuel filter is not particularly difficult with your own hands.

↑ Fuel filter location

A feature of the fuel system of such models as Lada Vesta and Xray, the price of which is exceptionally attractive, is its built-in design. What does it mean? First of all, the coarse and fine fuel filters in these models are built into their electric fuel pumps.

Moreover, these models have different types of electric pumps. If in the case of the Xray model they use a device identical to the one that can be found not only in Lada Largus, Granta or Kalina, but also in Renault Logan and Sandero, then the situation with Vesta is different.

The latest model has a different fuel pump. Its catalog number is 21800113900900. This, however, does not lead to a big difference in technical characteristics.

Signs of part wear

A sign of a clogged filter element is a pressure drop in the rail to 3.5-4 atmospheres, accompanied by problems starting the engine and increased fuel consumption. When idling, there are dips until the engine stops.

A clogged filter puts increased load on the electric pump, which begins to make a hum. If the described defects appear, it is necessary to remove the fuel cassette and check the condition of the filter and pump, since damage to the pump has similar symptoms.

↑ Frequency of its replacement

According to the automaker, the service life of fuel filters corresponds to the service life of the electric pump itself. Therefore, there are no exact recommendations regarding the frequency of replacement of this element from official representatives of the corporation.

Attention! The manufacturer guarantees the operation of only original car parts.

Despite this, car owners occasionally experience clogged filters. The coarse filter, which is a mesh, must be replaced, although this operation is now not so easy - it was easier on Grant. A different situation arose with the fine filter. It is made of paper and cannot be separated from the pump.

As a result, in order to avoid problems and the need for an entire fuel pump, it is recommended to refuel only with high-quality gasoline.

Why is it needed?

There is a coarse filter that comes first from the gas tank. After all, first the lid where the fuel tank is located is opened, a gun is inserted there, the magic button is pressed and the fuel flows. Yes, it takes a lot of your money along the way, but what can you do? The location of the tank can be on the left or right, but this does not play a special role. Coarse cleaning, which is a mesh that traps large particles of debris.

This is followed by a fine filter. This is exactly what we will talk about. This element is called a fuel filter. With its help, small particles are retained. But even they can penetrate your diesel engine or gasoline injector.

Dust, dirt, debris, rust elements. All this can penetrate the system, causing a clogged pipe, tube, valve, fuel hose, or fuel pump components. Nothing good will come of this if timely replacement is not made.

To understand how to replace the filter, which element to choose and how to choose an analogue for the device you are going to change, you need to have at least a basic understanding of such an important component of the car.

I suggest starting with varieties.

Kinds

Modern fuel filters installed on Ford Focus, Nissan Almera, Hyundai Solaris, Nexia, Mazda, Opel, BMW e60, Renault Logan and Megane, Kia Rio and many others have at least two degrees of purification.

• First degree. This is a rough cleansing that allows you to get rid of large contaminants. Not to be confused with a regular mesh in the tank, which is not available everywhere.
• Second degree. Fine cleaning. This is the main task that falls on the shoulders of the filter.

And here you probably have the main question - where is the filter device located? I don't know. No, I can answer, but if you tell me specifically what make of your car or what year of manufacture. After all, on the same Chevrolet Niva, different Opel, Toyota, Mazda models, on the Volkswagen Passat B3, as well as on the domestic VAZ 2114, 2112 and 2110, the location may differ.

However, they are always located somewhere between the engine and the gas tank, since the filter's job is to prevent contaminants from entering the engine while the fuel moves from the tank to the engine. What's in the gas tank itself? That's right, a coarse cleaning device. This is an additional filter element so that any unscrupulous gas stations do not spoil your car.

Now let’s talk about the types of filters themselves. What element will be on the car? It depends on the type of engine. There are three of them, as you know. Except for electric motors. Well, there is no need for a fuel filter, as you understand.

Therefore, there are three types of filters:

• carburetor;
• diesel;
• injection.

↑ Features of replacement

The electric fuel pump of both Lada models is located in the gas tank of the car. In order to gain access to it, you must first remove the cover from the latter and lift the rear seat.

As a result, the car owner will see a system consisting of:

• electric fuel pump module;
• clamping ring;
• fuel tank;
• wiring harness blocks;
• rear fuel pipe.

Each of these elements plays an important role in the operation of the fuel system. So, the wiring connects the pump to the pressure regulator and the gasoline level indicator. And the gasoline line serves to supply fuel that has already been cleaned by filters to the fuel module.

When replacing, it is necessary to strictly monitor all fragile elements of this system.

↑ Dismantling procedure

The procedure for dismantling the fuel module and fuel pump is the same for both Lada models that we are considering - Vesta and Xray.

You need to start by removing the rear seat in order to free up access to the module. After this, carefully disconnect the wires that connect the pump and the cover. If you replace one of the elements on the cover, you only need to disconnect the cable that is routed to it.

If the goal is to replace the filter, for which you need to get the pump, turn everything off.

Only after all electrical wires have been disconnected should the pump be removed when necessary.

↑ How the module is disassembled

As noted above, the procedure for disassembling the electric fuel module of a Lada Vesta or Xray depends on what exactly is planned to be changed. There are both specific features in case of replacing one or another element, and a general procedure, regardless of what exactly needs to be repaired.

In the case when the fuel level indicator sensor is changed, you need to:

• First, remove the wire end from the pressure regulator terminal.
• While simultaneously pressing the latches, remove the wire block from the cover.
• Using a flat-head screwdriver, release the retainer that holds the block.
• After the block is completely disconnected, you can remove the sensor itself. To do this, you need to press two special clamps from the grooves.

A slightly different disassembly procedure is provided if you plan to replace the pressure regulator:

• As in the previous case, you need to start by removing the wire tip.
• After this, helping yourself with a flat screwdriver, you need to remove the special spring-shaped retainer.
• Only after this can the regulator itself be removed from the module cover.

As can be seen from the two cases considered, the most important role when disassembling the elements of the fuel module is played by the correct disconnection of wires and clamps.

↑ How the replacement occurs

The fuel filter on the Lada Vesta is changed according to an algorithm similar to that used when disconnecting and replacing other parts from the fuel module. The main difference is related to both the shape of the coarse fuel filter and its location.

Important! This section describes how to replace the coarse filter, since the fine element cannot be replaced.

In this case, the procedure will look like this:

• You need to take a flat screwdriver and, using it to help yourself, disconnect the drain tube from the intake chamber.
• From the intake chamber you now need to remove all the springs that hold the guides and themselves. In this case, it is important to mark which spring was put on which guide.
• After this, you can begin to release the electric pump fuel module from the intake chamber. It is attached using three clamps, which must be removed.
• The coarse filter is a mesh attached to the pump. It is held in place by one spring.
• In order to remove the filter, you need to pry off the spring with a screwdriver.

Once the old mesh has been removed, you can install a new one and secure it with a locking spring. After this, repeat all the steps in reverse order and return the removed elements to their place.

Cabin filter Ford Focus 2: price and choice

Original cabin filter for Ford Focus 2 carbon. Thanks to the impregnation of the fibrous coating of the filter with carbon granules, the Focus 2 filter not only cleans the air of dust and other small debris, but also catalyzes burning vapors that come both from the engine of the car itself and from all harmful vapors entering the cabin. This filter is still included in the rating of the best air purification filters according to the most modern European standards and is installed on the Ford Focus 3 without changes. Well, except that they added two foam seals along the edges for tightness. The degree of air purification is from 85 to 95%. Price - from 480 (analogues) to 1200 rubles (original). More expensive than an air filter.

Before purchasing, check the Ford Focus 2 filter for mechanical damage. A normal original Ford Focus filter will cost from 750 rubles and above, do not skimp on your health.

Replacing the cabin filter on a Ford Focus 2

The cost of replacement at a car service is approximately 700 rubles.

When Ford engineers are stupid, they do it in such a way that even AvtoVAZ takes a break. During the design of the filter placement structure, they decided that even the “stupidness” could be worse than Russian engineers and made changing the cabin filter of a Ford Focus 2 torture. They shoved it under the dashboard, almost to the radio, and blocked the path to it with the gas and brake pedals. And they succeeded in this deceit. They probably just assembled the entire panel, installed the filter and put it on the car. How to change it is not their problem. Yes, replacing the air filter is much easier...

• Small ratchet
• Grille extensions
• socket heads for 10 and 8
• Flexible extension or driveshaft for ratchet

Replacing the cabin filter of a Ford Focus 3 is much easier, thank you that at least they thought of making the replacement easier on the next Focus model...

In general, the filter is located somewhere to the right and above the gas pedal. And in order to make the replacement, you either need to be no more than 30 cm tall, or have a very flexible boneless body and the super ability to turn the torso and head separately, at least 180 degrees. Even replacing the cabin filter in a Ford Focus 1 is easier. But on the new model, when Focus 2 came out, they decided to make this process more difficult. We take out the rug to get less dirty...

Ford Focus 2 has an electronic gas pedal; disconnect the plug from it by pressing the latch while simultaneously pulling the connector up.

And now, it’s time to take advantage of your bulging, long, illuminated eyes, which, according to the designers of Ford Focus 2, you also have. This is needed to unscrew the 3 pedal nuts, one at the bottom, two at the top. After all, both hands will be busy and you won’t be able to illuminate accurately. The designers of Focus 2 have all the listed abilities, since they thought that all other people could do the same.

In general, you see the studs on which the pedal is held - 2 on top, 1 on the bottom. And here is the electronic gas pedal of Ford Focus 2.

Then, we remove the cover and find a dirty, black with dust, dirty filter of the Ford Focus 2 air conditioner. It’s easy to find, but getting it out is a problem...

The Ford brakes also made the brake pedal a serious obstacle. The half-removed filter at the top rests against the pedal connection, clings with the back side to the gas pedal studs, folds almost in half and is thus removed.

The Ford Focus 3 cabin filter is the same, but has two seals at the ends of the filter for greater tightness

The Ford Focus 1 cabin filter is longer, it does not fit two...

The poor guy's condition, of course, was catastrophic... Be careful when installing a new filter. You, of course, will have to bend it “to death”, but do not overdo it and do not tear it on the studs of the gas pedal.

↑ Where can I buy

Purchasing an electric fuel pump, which is used in the latest Lada models, is not so easy. Its official manufacturer, the Japanese company AISIN, annually supplies this part to the market in insufficient quantities.

The easiest way is to contact official distributors. At the same time, there is no guarantee of the success of such an appeal.

Due to the current situation, more and more motorists are choosing a replacement in the form of similar type fuel pumps. This is about:

• 311111R000;
• 311111G500.

The first of them is used as a standard part of two popular car models - Hyundai Solaris and Kia Rio. And the second is for Kia Picanto, Hyundai Sonata or Elantra. All these models are Korean. This is due to the fact that the fuel system of Korean cars is also of Japanese origin.

Checking the canister purge valve

The control unit is located in the engine compartment, to the left of the expansion tank of the cooling system. The algorithm of actions is as follows:

1. We turn off the engine.
2. Open the hood.
3. Disconnect the block with wires. We check the terminals for oxidation and clean them as necessary.
4. We temporarily dismantle the control unit and check the resistance of the equipment with a multimeter (no more than 30 ohms).
5. Based on the diagnostic results, we decide on the advisability of replacing the CPA with a new one.
