A fuel pump of the regenerative turbine type has an impeller enclosed between a pump cover and a pump bottom, with a pumping chamber formed between the cover and bottom along the periphery of the impeller. A vapor purge orifice, having a chamfered inlet, a plurality of different diameter sections, and a chamfered outlet, leads to a vapor purge channel which runs radially along an outside portion of the pump cover. The purge channel has baffles through which the fuel vapor flows before exiting through at least one outlet into the fuel tank. Fuel vapor is more effectively removed from the pumping chamber by the smoother sections and chamfers of the purge orifice and its energy is effectively dissipated by the purge channel baffles, thus reducing pump noise and increasing pump efficiency.

An automotive fuel pump has a pump housing encasing a rotary pumping element which forms two non-communicating chambers comprising an inlet chamber in communication with a fuel inlet and an outlet pumping chamber in communication with a fuel outlet. The rotary pumping element has a ring portion along an outer circumference, a plurality of vanes around an inner circumference radially inward of the ring portion, and a plurality of axially extending fuel flow passages located radially between the plurality of vanes and the ring portion. Fuel passes from the fuel inlet to the outlet pumping chamber and from the inlet pumping chamber to the fuel outlet through the fuel flow passages in the rotary pumping element.

A fuel pump has a motor with a shaft extending therefrom and an impeller fitted thereon for pumping fuel from a fuel tank to an internal combustion engine. A pumping chamber, which encases the impeller, is comprised of a cover channel and a bottom channel formed in a pump cover and a pump bottom, respectively. The impeller has a plurality of radially extending vanes on an outer circumference separated by partitions of shorter radial length. The partitions are comprised of quarter-circle shaped arcuate portions extending from the outer circumference of the impeller to a straight portion having parallel sides, which preferably extend approximately 0. 1 millimeters to 0. 5 millimeters, to a flat top with rounded corners. Fluid active vane grooves thus formed circumferentially between the vanes and axially between the partitions which reduce fuel vortices angular acceleration within the pumping chamber thus increasing pump efficiency.
