Will this cap nut fit on any Char-Lynn piston pump? I got an older one.

Compatibility is what this Danfoss/Eaton S2 cap nut is all about, especially with Char-Lynn piston pump accessories. It's available in different configurations and sizes, so you should be able to find one that fits your older pump.
