ABSTRACT:
A fuel pump includes a housing, and a motor. A single sided impeller has first and second impeller flow channels each including a plurality of vanes. The impeller defines a flow passageway extending therethrough. A cover is attached to the housing and has a cover surface that defines first and second cover flow channels. The cover flow channels receive fuel from inlets formed in the cover. The first and second cover flow channels are aligned with the first and second impeller flow channels and receive fuel through the inlets and deliver fuel to outlets. A body is positioned within the housing and defines an impeller chamber to receive the impeller, and a first outlet passageway fluidically connected to the first cover flow channel and impeller flow channel. A second outlet passageway formed within the cover is fluidically connected to the second cover flow channel and impeller flow channel.
