The fuel module is usually removed to replace the coarse fuel filter, repair or replace the fuel level sensor, or to replace the electric fuel pump
The fuel module of the Niva car is submersible and is located in the fuel tank.
Before removing the fuel module, you need to make sure that the fuel in the tank is half the level.
To remove the fuel module, you need to remove the rear seat, for this:
Using a 13 mm socket, unscrew the four bolts securing the rear seat hinges to the body.
After releasing the seat back locks, lift the seat and remove it through the tailgate opening.
The hatch in the fuel tank compartment lid does not allow you to remove the fuel module, so you need to remove the fuel tank compartment lid.

Using a "7" head, unscrew five screws along the front edge of the cover and three along the back.
Moving forward, remove the fuel tank compartment cover.
Disconnect the connector electric fuel pump.
We mark the electric fuel pump tubes and fuel drain hoses with paint
Holding the hose nipple with a 17 mm wrench, unscrew the nut of the drain pipe of the electric fuel pump with a wrench of the same size.
First, unscrew the nut at a small angle, releasing the fuel pressure.
We move the hose.
The connection is sealed with a rubber ring, which is replaced with a new one during assembly.
In the same way, disconnect the hose from the fuel supply pipe of the electric fuel pump.
Using a "7" head, unscrew the eight nuts securing the electric fuel pump to the fuel tank.
Lift the electric fuel pump and, turning it clockwise, remove it from the tank, trying not to damage the fuel gauge float
