B-I-L has it nailed. I buy the pump seperate at NAPA, P/N 2-4218. I really don't know but I suspect it may be the same # for all YF's. I'd buy their rebuild kit, give them your carb# for that, & do it all while I'm at it, you'll need the gaskets anyway, but you still need this # as its not included in the rebuild kit.
