Abstract:
An electric-operated fuel pump assembly (20) has a vaned impeller (36) that is disposed within a pump housing (28) for rotation about an axis (22). A channel (44; 72) extend arcuately about the axis. A vapor vent hole (46; 46A) intersects the channel. Certain geometric relationships improve venting efficiency, and hence pump efficiency.
