    NOS Fuel Pump for 1937 Buick Series 40

    I have located a NOS fuel pump, an AC 421 (609454) for 1935-36 Chevrolet. Will this fuel pump work on my 37 Buick, series 40?

    nos fuel pump for 1937 Buick series 40

    Thanks for the advice! - I was also thinking, since my Buick does not have an original AC fuel pump but an aftermarket model, that I could also locate an original AC and then rebuild it with modern diaphragm/gaskets.

    Just because it is an AC pump, but was made for a Chevy, doesnt make it any more authentic than the aftermarket pump you have now. You want a pump made for your Buick. If Bobs doesn't have one try Antique Parts Cellar. They made me a new one with spare parts from AC.
