Note: If the pump is faulty, it can be replaced with a new one, as well as the entire unit, since its functioning is very important for the correct operation of the injection system.
1. Apply the handbrake, use a jack to lift and place the rear of the car on a stand, and disconnect the battery ground wire clamp.
2. Disconnect plug 2 from the front of the pump (figure 3.5).

4. Unscrew the three bolts securing the pump to the pump tank and remove the support wheel, pump and sealing ring. It is important to ensure that no debris gets into the pump or tank - this is very important.
5. Installation is performed in the reverse order of removal. Do not forget to install a new sealing ring between the pump and the tank.
Caution: It is important to remember that the impeller and brush set of the pump motor actually operate in the fuel inside it. The fuel is also a cooling, lubricating and anti-sparking agent. For this reason, the pump should not operate without fuel inside it, otherwise it will overheat and may wear out and catch fire.
6. The fuel filter is mounted on the side surface of the pump tank. To remove the filter, unscrew and remove the fuel pipe connections at both ends of the filter. Each connection has one sealing washer on both sides. Loosen the bolt on the clamp that secures the filter to the pump tank and remove the filter.
7. Installation is performed in the reverse order of removal. When installing the fuel filter, make sure that the arrow on the filter shows the direction of fuel flow.
