Fuel pump is one of the basic components of EFI vehicle fuel injection system, which is located in the vehicle fuel tank. The fuel pump works when starting and the engine is running. If the engine stops and the ignition switch is still on, HFM-SFI control module turns off the power supply of the fuel pump to avoid accidental ignition. The function of the fuel pump is to suck the fuel from the fuel tank, pressurize and deliver it to the fuel supply pipe, and cooperate with the fuel pressure regulator to establish a certain fuel pressure. We offer petrol fuel pump, gasoline electric fuel pump, car petrol pump and so on.
