Abstract: A regenerative fuel pump comprising a housing, a pump cover having a first flow channel formed therein, a pump body having a second flow channel formed therein whereby the first flow channel and the second flow channel define a pumping chamber, and an impeller mounted between the pump cover and pump body and including a plurality of vanes spaced circumferentially about the impeller and defining a plurality of vane grooves. The vanes are spaced un-evenly in a non-repeating pattern about the impeller. The first and second flow channels each include an inlet end, an outlet end, and a stripper area defined as the area between the inlet end and the outlet end extending from the inlet end away from the flow channel. Each of the stripper areas including a plurality of grooves formed therein adapted to dampen pressure pulsations within the pumping chamber.
