Re: napa # for fuel pump/mercruiser 140
They have to look it up under a Sierra number. Most, but maybe not all, NAPA stores sell the Sierra brand of Marine parts.
And you don't want to look up marine parts under an automotive number. Auto fuel pumps, carbs, distributors, starters, alternators, etc, are not to be used on boats. They are not coast guard approved and the are a spark/fire/and explosion hazard.
