All Exergy HP4 pumps include upgraded internal bushings which are much more resistant to low lubricity fuel and provide a longer service life compared to the original factory pump. These gains in longevity were proven with years of internal testing at Exergy to extend HP4 pump life and are now available in all HP4 pumps Exergy sell.
