ABSTRACT:
An electric in-tank fuel pump for vehicles which is provided with a noise-reduction jacket of relative soft material spaced from the pump housing by internal projections on the jacket which contact the pump housing. An extended skirt on one embodiment serves to collect vapor which rises in the jacket to maintain a low liquid fuel level around the pump. A quick connect-disconnect from the pump to a fuel line with an integral unidirectional valve is provided to maintain fuel line pressure when the pump is not operating. Also, an inlet unidirectional valve is provided to prevent fuel from siphoning out of the pump.
