<p>A vehicle regenerative-type fuel pump reduces the possible accumulation and effects of contamination relative to impellers (20) with outer ring members (54). The outlet port (34) on the pump cover member (24) is enlarged and a C-shaped groove (70) is positioned radially outwardly, which causes an increased outlet area and fluid flow around and through the impeller (20) and through the outlet port (34).</p> |
