"My Crusader manual only goes
"My Crusader manual only goes back to '87. The Sierra fit list is very generic. I found three different mechanical pumps used on the 454 between '87 and '96. None of them use the number the Sierra pump claims it replaces, although that number is a good P/N in the Crusader price book and it does list it for a 454, it just doesn't tell you which one. If you want to be sure before you buy one, call Mike Genna at Crusader (586) 977-0100, he won't sell you the part but he will be able to tell you if that Sierra pump will fit. Good luck."
