- 10 - ABSTRACT A fuel pump has a pump cover with an inlet through which fuel from a fuel tank is drawn by an impeller to a pumping chamber formed by a pump bottom and the pump cover. The inlet has divergent sides oriented such that fuel being pumped is routed radially outward of primary vortices in a section of the pumping chamber adjacent the inlet to a section of the pumping chamber opposite the inlet. In a first embodiment, the upper side of the inlet is oriented at approximately a 10 to 12 degree angle from the lower side. In a second embodiment, the upper side is oriented at approximately a 127 degree angle from a line parallel the shaft rotation, and the lower side is oriented at approximately a 139 degree angle from the same line.
