MBF Posted January 17, 2008 Report Share Posted January 17, 2008 I need to replace the waterpump in my '52 1 ton. NAPA sells 2 different pumps but doesn't stock either in their local store. This is the longer of the 2 offered-any idea what the p/n is? Thanks-Mike F Quote Link to comment Share on other sites More sharing options...
Young Ed Posted January 17, 2008 Report Share Posted January 17, 2008 Mike I think the 2 different pumps are just the bypass and non bypass versions. I've never seen a longer one. Quote Link to comment Share on other sites More sharing options...
MBF Posted January 17, 2008 Author Report Share Posted January 17, 2008 I had a new unit that came w my truck that I used on my '36 plymouth over the summer in order to get it to a show w/o waiting for a rebuild. That pump was slightly longer than the one that came off the car (both were bypass type). Since the bolt patterns are the same, I can either have the core from the '36 rebuilt, or purchase a new unit-which I'm inclined to do-but I don't want to have alignment problems w the pulleys. Thanks-Mike Quote Link to comment Share on other sites More sharing options...
Don Coatney Posted January 17, 2008 Report Share Posted January 17, 2008 (both were bypass type). Internal or external bypass? There is a difference. Quote Link to comment Share on other sites More sharing options...
