Rebuild kit for an AC #4657 fuel pump

[Garry E.]

I want to rebuild the AC #4657 fuel pump on my '64 (327/300HP), but I can't find anyone local that sells a rebuild kit for the unit..... I've checked NAPA, Auto Zone, O'Reilly's, etc..... everyone wants to sell me a replacement pump - not the rebuild kit.... I know that Long Island Corvette sells a kit (don't know who makes it....) but I'm looking for someplace local to buy it.

Does anyone have any thoughts on this....?

Forget the name, but there's a fellow on Grand Ave (between McDowell and Camelback - deals mainly in Cadillac) that used to advertise AC Fuel pump kits. Good luck!

I just finished up my 4657 rebuild yesterday....and yes I was shocked that NAPA didn't have the kit (or at least couldn't find it). Paragon and Zip apparently have the same kit so I went with the Zip kit (for no particular reason). It didn't include gaskets for the poppit valves which I have seen in some early kits... But the pump is back on the car and working well... It only took a couple of days to get the kit, if that's your concern. I would avoid unknown sources - especially "white box" Chinesium stuff...I've heard they can result in over-pressure and cause flooding issues.
