If you get a core pump there is a rebuild kit for the "chrysler" or "federal" pump and one for the saginaw.I just rebiult my chrysler for $15.00 at oreilly's.The saginaw was $5.00 for the kit which is tear drop shaped and the chrysler is round with a round fill tube.But if you do rebuild get the "lone-a-tool" pully puller.I had to go back to get its as nothing I had would pull that thing off.
