Replace vs Rebuild?

[tommays]

I dont like to disagree with cardiacpaul


BUT if your going with and electric fuel pump it does need to be MARINE AND IT DOES need to be wired correctly so that it ONLY runs when your cranking and uses and oil pressure switch to keep it running after the motor starts


You also need to use real A1 marine fuel line


If you pop auto parts into a marine gas motor and it pops or burns you will have insurance issues and could end up killing yourself

Gasoline fuel pumps tend to be "ignition" protected no matter what the application, land or marine. It isn't like alternators, where the marine models have additional vapor-ignition protection. I suppose a pump designed for the land market might have a nice aluminum casing which promptly pits away in salt air, but I don't think an insurer would bother looking all that closely at whether a pump was USCG approved, the claims value on any old boat with an A4 in it just isn't going to be all that high. (And the pump maker could be held liable in any case.)

I'd have to agree with cpaul, that's not one to lose sleep over. But like anything on a boat--and all too much of anything in stores these days--you need to eyeball it and see if it has been built right for your needs.

I'd disagree on the starting fluid, though. Flammable vapors below? No need, just spray the same areas with Windex or plain water, if the engine speeds up then stumbles it has ingested the spray. (Speeds up as the water blocks the leak, stumbles as the water gets into the cylinders.) Some mechanics also use propane from an unlit torch--which works the same as starting fluid, more or less. Still a flammable gas problem on a boat, I'd prefer the spray bottle.
USCG approved Windex, of course. (VBG)

If you are on the west coast, I would be interested in buying your A4.
