If the vehicle is operated in dusty conditions or with low-quality fuel, the filter must be replaced more often than specified in the regulations.
The fuel filter is located in the engine compartment and is attached to the front shield.
The fuel in the engine fuel system is under pressure. Therefore, before servicing the fuel system, it is necessary to release the fuel pressure. To do this, with the ignition off…
…we remove the fuel pump fuse (EF 16) from the mounting block in the engine compartment.
We start the engine and let it idle until it stops due to the fuel running out in the system. Then we turn on the starter for 2-3 seconds. As a result, the pressure in the fuel system will be released.
Using pliers, squeeze the "antennae" of the plastic retainer of the fuel outlet pipe tip..
…and remove the tip from the filter fitting.
We remove the fuel filter from the bracket on the front panel.
By squeezing the "antennae" of the retainer, we remove the tip of the supply tube from the filter nipple.
We install the filter in the reverse order. In this case…
…the arrow on the filter housing should point towards the right side of the vehicle.
We put the tips of the fuel pipes on the filter fittings until the clamps snap into place. Having installed the fuel pump fuse, we turn on the ignition and check the tightness of the connections.
Fuel filters are sold complete with plastic clips.
Therefore, when removing a filter from a vehicle that has reached the end of its service life, you do not have to worry about damaging the fasteners.
When installing a new filter, do not apply excessive force to the fasteners so as not to break off the "antennae".
If after replacing the fuel filter the connection of the nipple to the fuel pipe does not provide a tight seal, most likely the reason lies in the damaged sealing ring of the fuel pipe. To replace the ring, use a thin screwdriver or tweezers.
