  • I have a 1995 Chevy Silverado 2500 5 spd with a 6.5 ltr T-Diesel and need to verify this will fit? Secondly is this a high efficiency pump or upgrade from stock? Is itbetter than the upgraded AC Delco 251-603? Do you have this with the ability to fit the hayden radiator fan NUT? Thanks.

    This item will fit. This is an Alliant Power stock replacement item. Good quality factory replacement. No we do not have offer that option on this water pump.
