Abstract
A fuel pump includes a pump housing with a motor which is adapted to rotate a shaft with a ring impeller mounted thereon. A bottom is mounted to the housing and has an outlet. A cover is mounted on an end of the housing and is attached to the bottom with the ring impeller enclosed between the cover and the bottom. The cover includes a first side having a fuel inlet orifice and a second side having a flow channel formed therein. The inlet orifice extends through the cover in fluid communication with the flow channel. The flow channel includes an inlet, a ramp, a ramp end and a main channel. The inlet includes a smooth curved profile. The ramp connects the inlet to the ramp end. The ramp end connects the ramp to the main channel.
