47- P15S is stalling on uphill slopes


Recommended Posts

I'm at work at the moment, but I sent my wife to get a fuel line from a local store that deals in classic ford parts (didn't know about it last year). She was able to pick one up for $15, so tonight I'll stick it on and make sure that there's no air leaking into the system.

Got home and pulled the fuel pump apart, the diaphragm is pooched. Was looking at online retailers, has anyone had good experience with a place like Rockauto?

Personally, I'd get a kit from Antique Auto Parts Cellar and rebuild it myself. They make a quality kit with materials compatible with modern gas. Probably last longer than the new pumps being sold now.

That sounds better, the only thing bad about the pump is the rubber diaphragm, so it seems like a waste to get a whole new one. But I have found a guy by me who's willing to give me a pump out of his wife's plymouth as she wants a hemi in it. Crossing my fingers that it's in good shape.

If it starts right back up (when your still on the hill) then it has to have gas in the bowl. A weak fuel pump problem would also show itself on acceleration.

One thought - distributer vacuum advance should kick in when vacuum increases, such as lugging up a hill. Perhaps the vacuum advance is not working.

Perhaps the vacuum advance is not working.

Or it is working and as the advance plate in the distributor rotates the is a short or break in the wire an you are losing the spark.

Thanks for all the advice. I've changed out the fuel pump and now have vacuum, the wipers are working. When we were cleaning her for the car show, we blew about 5 lbs of dirt out of the radiator (feeling dumb for not checking that first), so she's cooling fine now. We made it down to the car show and back with no problems, but it was only about a 10 block drive. When we took her out Sunday for a longer trip she started sputtering and stalling again. Our next check now is to check the distributor and the plugs.post-7163-0-38292900-1408387129_thumb.jpg
