When to change the fuel filter Peugeot 308

The quality of gasoline at gas stations in our country is growing rapidly, but not as much as we would like. Anticipating this, the designers of state employees of the French company PSA, in particular, Peugeot 308, use various fuel filters in the fuel supply system. Where is the fine fuel filter located, how to change it and which one is better, it was decided in detail.

According to the official data of the PSA service, nothing needs to be changed, and the fine fuel filter should last forever, until the end of the car's life. This may be true in France, but our gasoline, laced with sand and road dust, clearly needs more attention to the fuel purification system. Also, many Peugeot 308 owners are firmly convinced that there is no fine filter in their fuel supply system. And he.

Manhole in which the fuel module with coarse and fine filters is installed

In the Peugeot 308 of any edition with an injection gasoline engine, the fuel fine filter is located directly in the gas tank and is made in the form of a separate cassette connected to the fuel module. Access to it can be obtained either by removing the fuel tank, which is long and impractical, or from the passenger compartment through a special hatch, folding the back of the rear seat cushion (Peugeot 308 SW).

Symptoms for which it is worth changing the Peugeot 308 fuel filter

Kilometers run, but there are clear signs that the fuel filter has already worked. First of all, this will affect the operation of the fuel pump electric motor, it will be more difficult for it to push gasoline through the system, and this will be expressed as noise even when the ignition is turned on. A clogged fuel filter will inevitably lead to a drop in pressure in the power system, and this will lead to increased fuel consumption, drops under load and at high speeds, unstable and difficult engine starting, especially in the cold season.

In addition, errors related to rich or lean mixture can occur, as the electronic control unit will try to make up for the lack of gasoline in the combustion chamber, which will cause an imbalance in the sensor readings.

The error scanner can also display messages about ignition problems, lambda probes, and many others. Summing up the main signs of a clogged filter, we get a considerable list:

• failures during acceleration and under loads;
• high fuel consumption;
• noisy operation of the fuel pump;
• unstable idle;
• pressure drop in the power supply system;
• Check Engine, engine management system memory errors;
• difficult start;
• violation of the temperature regime of the engine.

Which fuel filter is better to buy for Peugeot 308

The situation on store windows and Internet sites with fuel filters for the 308 Fawn is constantly changing, but the public has already identified its favorites among the whole variety of all kinds of filters. The original Peugeot 308 fuel filter can be found in databases as a filter for Nissan models (Qashqai, Micra), as well as for various Citroen and Renault models, for Opel Astra of recent years of production and a number of other cars

New filter assembly with corrugations

There is no original number, as the factory believes that it should not be changed. It will also be necessary to change the filter mesh Francecar FCR210141. Also useful is the sealed cover of the fuel module 1531.30, the gasket of the fuel module 1531.41. If there are no corrugations complete with a filter, we take any from VAZ 2110-2112.

The price of a fuel filter for Peugeot 308 is from 400 to 700 hryvnia. As we have already said, it is desirable that the kit includes corrugated tubes, as in the Zekkert KF5463 filter.

How to replace the Peugeot 308 fuel filter with your own hands quickly

The cost of replacing a filter at a service station ranges from $ 35-40, so it's better to save money and replace it yourself. To replace, we need a standard set of tools, as well as a set of consumables. Here.

1. Old washer for attaching the module. 2. New filter. 3. Corrugation VAZ 2110 4. New washer. 5. Detergent.

The detergent did not get here by chance, as a lot of dust accumulates under the seat in the hatch. It must be carefully removed; getting it into the tank, as we understand it, is highly undesirable. Let's start with the depressurization of the power system. This can be done in one of two ways: remove the fuel pump fuse (in the engine compartment it is the top left fuse) or disconnect the power cable directly on the fuel module. After that, we start the engine and wait until it stops on its own, having worked out all the fuel on the highway.

Remove the fuel pump fuse

Next, we proceed according to this algorithm.

We recline the seat, fold down the valve on the floor lining Pry off the hatch cover with a flat screwdriver Disconnect the power connector from the module Disconnect the fuel lines Slide the lock washer counterclockwise Take it ... Carefully remove the pad Loosen the cup lock We come to the grid, remove it

Now we disconnect the connectors inside the fuel module, remove the corrugated hoses and disconnect the fuel filter assembly with the housing so as not to damage the fuel level sensor.

It remains to warm up the new corrugations with a building hair dryer and carefully install them in place.

We assemble in reverse order. Be sure to replace the washer seal with a new one, replace the washer if necessary. It is better to twist with pliers with a lever as shown in the photo.

After assembly, we pump fuel into the power system by inserting the fuse in its place (with the ignition on, let the pump run), after which you can start the engine.
