Fuel supply system
The fuel supply circuit includes the electric pump, the filter, the pressure regulator, the electro-injector
and the fuel delivery pipes.
The electrical pump is located in the tank from which the fuel is pumped and sent to the injector through
the filter.
The pressure is controlled by the pressure regulator situated in the pump assembly in the tank.
