The fuel pump if to look in the movement direction, is located on the car bottom on the right before the back bridge.

1. Disconnect from the plug of the storage battery a weight wire (–).

The anticreeping code of radio is thus erased.

2. Reduce pressure паров fuels, for this purpose quickly open a cover of a bulk mouth of a fuel tank.
3. Remove a protective casing (69), previously having noted its assembly situation.
4. Disconnect from clips inlet (53) and pressure head (52) pipelines, and also a ventilating hose (66) with standard shlangovy clips. Mark hoses a sticky tape for simplification of installation.
5. Unscrew on the fuel pump the pressure head pipeline with a hollow bolt. The remains of the spilled fuel wipe a rag.
6. Remove an inlet hose, previously having weakened a shlangovy collar.
7. Take a trunk floor sheeting.
8. Remove a protective casing of a cable well and a protective rug.
9. Separate shtekkerny connection on the fuel pump and deduce it through a trunk floor. For this purpose squeeze out the rubber plug.
10. Disconnect from a spring clip on the holder an electric wire.
11. Remove a ventilating hose (66), previously having weakened a shlangovy collar (66а).
12. Remove an inlet fuel hose (53), previously having weakened a shlangovy collar (53а).

Otherwise at direct contact of the fuel pump with the holder there can come contact corrosion of metals.
2. Screw the fuel pump on an arm.
3. Get a ventilating hose and fix it a collar.
4. Get an inlet fuel hose and fix it a collar.
5. Enter an electric wire through the bottom of a luggage carrier and connect the tip. Condense an opening in the luggage carrier bottom with the rubber plug.
6. Establish isolating rug and a protective casing for a cable well.
7. Establish a sheeting of the bottom of a luggage carrier.
8. Insert an electric wire into spring clips on the holder and fix by means of linear clamps.
9. Screw топливопровод by means of a hollow bolt and with a new copper sealing ring (62). Rough moment of an inhaling of 25 N of m.
10. Remove shlangovy clips.
11. Establish a protective casing.
12. Connect to the storage battery a weight wire (–).
13. Expose time on hours.
14. Enter an anticreeping code of radio.
