The electric fuel pump is designed to create pressure in the fuel system and supply fuel through the fuel filter to the injector unit.
The submerged electric fuel pump is quite complex, located in the gas tank and structurally integrated with the fuel return channel and fuel gauge tube. It has a special fitting for checking the pressure generated by the pump. It must be at least 2.5 kg / cm2. You can check it with a pressure gauge and from a tire pump. The pump is accessed through a hatch under the rear seat cushion. At the inlet of the fuel pump there is a filter, which should be the first to clean the gasoline entering the system.
The fuel pump is located in a special well, in which there should always be gasoline.
