For a fuel pump manufactured since 1988, the M6 threaded terminal is positive, and the M5 threaded terminal is negative. The fuel pump has a non-separable design, so when it fails, it is replaced.
Order of execution
1. On pre-1988 models, remove the sensor (see fig. Details of the fuel tank of cars produced before 1988) fuel level similar to models with carburetor engines (cm. pp. 1–5 subsection 6.1.9). Remove the pump from the tank through the hole for the fuel level sensor.
2. Install the pump in reverse order. When installing, make sure that the rubber pads of the pump fit on the pins of the bracket located at the bottom of the tank, and the spring holders snap into place.
3. On models since 1988 to remove the pump (see fig. Details of the fuel tank of cars manufactured after 1988) special tool required (VAG 3214). Turn the pump 15 mm to the left with it and pull it out of the tank together with the holder, disconnecting the fuel line and electrical wires.
4. Install the pump in the tank so that the mark on the holder (see fig. Fuel pump since 1988) matches the first mark on the fuel tank as shown in the figure. Fix the pump by turning it with a special tool so that the mark on the holder coincides with the second mark on the fuel tank.
