Warning! Gasoline is extremely flammable and explosive, so care must be taken when working on any part of the fuel system.
Warning: The container that held the fuel contains fuel vapor and is potentially explosive.
Attention! Work on the fuel system must be carried out in a well-ventilated area, for which you can open all the windows and doors to create a draft.
Warning! When working on the fuel system, do not use open flames, electric welding or tools that may generate sparks. Make sure that a charged fire extinguisher is in the immediate vicinity of the work area.
Warning! Use goggles to protect your eyes from fuel getting into them. If fuel gets on your skin, rinse the area with plenty of water.
Caution! When working with the fuel system, keep it clean, as dirt that gets into the fuel system channels can block them, which will disrupt the normal operation of the engine.
Removal
Models with a single fuel pump
Fuel pump location on single pump models
A – connecting bolt;
B – electrical connectors
1. The fuel pump is installed under the bottom at the rear of the vehicle.
2. Relieve pressure in the fuel system.
3. Remove the ground cable from the battery.
4. Raise the rear of the vehicle and support it on stands.
5. Unscrew the screws and remove the protective cover of the fuel pump, fuel filter and pressure accumulator (see fig. Unscrewing the screws securing the fuel filter protective cover).
6. Label and disconnect the electrical connectors from the fuel pump (see Fig. Location of fuel pump on models with a single pump).
7. Using clamps, pinch the fuel lines connected to the fuel pump.
8. Disconnect the fuel lines from the fuel pump. If using bayonet connections, remove the sealing gaskets.
9. Remove the screws, remove the retaining strap and remove the fuel pump from the bracket.
Models with two identical fuel pumps
Location of fuel pumps on models with two identical pumps
The arrow indicates the fuel pump mounting belt.
1. Later models are equipped with two identical fuel pumps. Removing the fuel pumps is done in the same way as on models with a single fuel pump. It should be noted that the second fuel pump is installed under the first, and they are secured with a common belt (see Fig. Location of fuel pumps on models with two identical pumps).
Models with primary and secondary fuel pumps
Primary fuel pump location
A - Primary fuel pump;
B – rubber fastening elements;
C – differential housing
1. Later models of the Wagon are equipped with a primary and secondary fuel pump. Removal of the secondary fuel pump is performed in the same way as on models with a single fuel pump.
2. The primary fuel pump is mounted with rubber elements above the rear of the differential housing (see Fig. Primary Fuel Pump Location).
3. Relieve pressure in the fuel system.
4. Remove the ground cable from the battery.
5. Raise the rear of the vehicle and support it on stands.
6. Disconnect the fastening straps and remove the protective cover of the fuel pump and bracket.
7. Label and disconnect the electrical connectors from the fuel pump.
8. Using clamps, pinch the fuel lines connected to the primary fuel pump.
9. Disconnect the fuel hoses from the fuel pump. If using bayonet connections, remove the sealing ring.
10. Remove the fuel pump from the rubber mountings.
Installation
1. Installation is carried out in the reverse order of removal, taking into account the following points.
2. Check that the fuel pump mounting strap is properly installed on the anti-corrosion plastic insulating tube.
3. Install new gaskets in bayonet type connections
4. Start the engine and check that there are no fuel leaks from the lines connected to the fuel pump.
