Warning. Before starting work on replacing the fuel filter, read the safety rules for working with the power system (see "Safety measures for car maintenance and repair").
Removing
1. We prepare the car for work (see paragraphs 2b and 4 "Preparing the car for maintenance and repair").
Recommendation. In the absence of a viewing hole or overpass, this work can also be done on a flat area. But in this case, it is necessary to hang out the rear of the car.
2. Relieve pressure in the fuel line (see "Fuel Line - Pressure Relief").
Warning. Depressurize the fuel line even if the vehicle has not been driven for a long time. After depressurizing, a small amount of fuel remains in the fuel line.
3. Wipe the fuel filter and the fuel lines connected to it with a cloth. We process the thread of the coupling bolt of the filter fastening clamp with a penetrating lubricant.
Recommendation. Before disconnecting the tip of the pipe from the fuel filter, prepare a small wide container with a volume of at least 0.5 liters to drain the remaining gasoline from the fuel line. To completely remove the fuel, it is necessary to unscrew the spool from the fuel rail or open its valve (see "Fuel Rail - Operating Pressure Check").
4. By car with a VAZ 2112 engine (l,5i):
A) With a 19 mm open-end wrench, holding the fuel filter from rotation by the hexagonal pipe, with a second 17 mm open-end wrench, unscrew the fitting of the fuel supply line (1).
b) Disconnect the fuel outlet in the same way (2).
Warning. Rubber sealing rings are put on the ends of the fuel lines. Damaged rings must be replaced.
By car with a VAZ 21124 engine (l,6i):
A) Press on the spring clip.
b) While holding the latch in the pressed position, remove the connecting tip of the fuel line tube from the fuel filter outlet pipe.
V) Similarly, remove the connecting tip of the fuel line tube from the fuel filter inlet pipe.
5. Using a 10 mm wrench, unscrew the coupling bolt of the fuel filter mounting clamp.
6. Remove the fuel filter from the clamp.
Installation
We install a new fuel filter on the car and all the removed parts in the reverse order.
Warning. Pay attention to the arrow on the fuel filter housing indicating the direction of fuel flow. On a car with a 2112 engine, the engine (1,5i) the arrow should be directed to the left, and on a car with engine 21124 (1,6i) - to starboard.
After connecting the fuel line pipes to the fuel filter, turn on the ignition for 5 seconds and check the tightness of the connections. In case of fuel leakage, we replace the sealing rings in leaky fuel line connections.
