Abstract
A vehicle regenerative-type fuel pump which reduces the possible accumulation and effects of contamination relative to impellers with outer ring members. The outlet port on the pump cover member is enlarged and the C-shaped grove is positioned radially outwardly, which causes an increased outlet area and fluid flow around and through the impeller and through the outlet port.
