Abstract
A centrifugal fuel pump with a baffle disposed between a fuel inlet and an impeller of the pump. The baffle overlies the inlet opening and substantially prevents the impeller from producing a backflow of fuel through the inlet. The baffle also directs incoming fuel into a generally circumferential flow into the channel of the pump through which fuel is moved and its pressure increased by the rotating impeller. This improves the efficiency and maximum capacity of the pump.
