<p>A vehicle regenerative-type fuel pump (10) which reduces the possible accumulation and effects of contamination relative to impellers (20) with outer ring members (52). The outer ring members (52) have non-uniform configurations (slanted, curved, grooved, etc.) which reduce the affects of contamination which can cause wear and roughing of the outer surface resulting in higher torque and reduced pump efficiencies.</p> |
