ABSTRACT:
A fuel pump apparatus having two-stage pump sections and a vapor discharge port. A first impeller of a first stage pump section is attached to a vertically lower surface of a second impeller of a second stage pump section, the second impeller having a larger diameter than the first impeller. A vapor discharge port is formed in the second impeller at a radially inward portion thereof to open to a radially inwardly portion of a first pump passage. Fuel vapor is separated from liquid fuel at the first stage pump section and the liquid fuel is pressurized at the second stage pump section.
