Fuel pump is the auto parts industry jargon. Is one of the basic components of automotive efi fuel injection system. Role is sucked out, pressure in the fuel from the fuel tank after delivery to the delivery pipe, and the fuel pressure regulator to cooperate to build a certain fuel pressure.

Fuel pump by an electric motor, pressure limiter, check valve, the practical work of electric motors in the fuel oil pump shell, don't worry, because there is no any shell to ignition, fuel can lubrication and cooling motor fuel, oil outlet is equipped with check valve, the pressure limiter is in the pressure side of the pump shell, with to the inlet channel.

Fuel oil pump pressure depends on the pressure limiter standard, if the fuel pump pressure exceeds a limit, the pressure limiter will open the bypass to fuel flow back to the fuel pump inlet.
