An electric fuel pump mountable in a fuel tank for pumping fuel to an internal combustion engine. A casing of the fuel pump is mountable at a bottom wall of the fuel tank and has a fuel inlet at a lower end and a fuel outlet at an upper end so that the fuel is pumped upwardly through the casing. A vent valve is disposed at the top of the casing and is closed when the fuel pump is operating and opened when the fuel pump is deactivated. A conduit has one end connected to the vent valve and an opposite end which is open and located at a level in proximity to the bottom of the fuel tank so that when the fuel pump is deactivated the conduit serves as a suction passage to fill the casing when the fuel level in the fuel tank drops below the top of the casing to enable restarting of the engine without delay.
