HELP - replacement fuel pump '41 Six

Hi folks -



This is probably overly long but please bear with me....



My trusty driver died the other morning, fortunately while in the garage. It refused to start, and I traced the problem to "no fuel coming from fuel pump." Further troubleshooting revealed telltale signs of a dead fuel pump: full tank, new fuel line to replace flex line, still refuses to suck fuel from the tank; oil seems thin and smells of gasoline. I've ordered a rebuild kit from "Then and Now" in Boston. The engine is a 212 flathead six, and the pump is a single-action type with separate sediment bowl, facing downward, to the rear of the actual pump housing.



However, I also wanted to (at least temporarily to get back on the road) try a new replacement pump. I read all the threads I could find on fuel pump replacement, and purchased an AMC replacement pump (#6737) from Auto Zone for $19.00. However, it doesn't seem to fit: the lever doesn't seat in the cam follower properly. I couldn't even line it up. I pretty much gave up on this approach because I was afraid of damaging the cam follower. I've also ordered a Pinto style pump from NAPA (#6748) which should be in tomorrow. The #6748 at Auto Zone had three fittings, which includes a return line to the tank. I didn't know what to do with that line, so I didn't buy the pump. I'm hoping the NAPA pump only has two fittings and will fit in place of my existing OE pump, but most likely it will be the same as the other pump.



I had planned to just use an inline filter, and if the pump had three fittings, to "T" the small fitting back into the input line.



If the Pinto pump doesn't fit, are there any other options for getting my faithful steed back on the road while I'm repairing the OEM pump? And, are there any "gotchas" I need to be aware of while doing all this? (It looks like both new mfr. pumps mount "upside down" to get the lever in the right position).



Thanks....

    Ah, I'm afraid those pumps will only fit the 232, 262, 308 sixes and stepdown (wide block) 254 eights.



    Get a new diaphragm from

    or have Dave Kostansik swap yours for a rebuilt one.

    Thanks for the quick answers!



    I was afraid of that! I have already ordered the rebuild kit from Then and Now, and I guess I'll just have to wait for that. Pfui.



    At least I have a couple options: first I'll try the rebuild myself, and if I can't get that to work out, I'll do a swap with Kostansik for one of his rebuilt ones.

    Thanks! I checked it out and my original pump is slightly different from that particular one. All the NOS pumps on eBay have the same problem as mine: they need to be rebuilt with new materials.



    Mine is not in that bad shape, except probably the diaphragm is shot. Since I can't get an aftermarket pump that will work, I've decided to get the kit from Then and Now and try a rebuild myself.

    In preparation for receiving my rebuild kit, I removed the pump and disassembled it. The pull rod would not release from the rocker arm. It appeared that some time ago the pump had been overhauled, and several places were permanently staked rather than fastened with snap rings or nuts. Anyway, I broke the pull rod end when I attempted to free it. Nuts. At least I discovered that my diaphragm was leaky. There were traces of gas on the engine side of the rocker, where the pump attaches.



    So I was on eBay after all, and bought a NOS pump that I will probably have to overhaul to replace the diaphragm. Ah well. I decided that it would be a good idea to have a spare fuel pump on hand, so I am also purchasing a rebuilt pump from Kanter -- I tried to call Kostansek but was unable to get an answer. I hope I have better luck with Kanter than several other HET members have. I wasn't too impressed with their "bedside manners."



    All in all this was an - adventure - so far. I used to work on restoring airplanes, and this is a LOT less expensive and time consuming, if a bit more grimy (airplanes are not nearly as dirty as cars to work on). And once again, I have to say that I greatly appreciate the quick response I've gotten from HET forum members whenever I have a question.

  • Ed. Before I installed a NOS pump I would put a new kit in. The old NOS pump diaphragm will go bad in a short time and fill the crank case with gas. The only way to get all the gased oil out is to remove the pan and clean it. I have used several kits from Then and Now and had no problems. They can also build you a new pump.

    I'd thought of that, but I want to keep the car as original as possible. If I have no luck with mechanical pumps, I'll try the JC Whitney route. (The car is almost totally original, as near as I can tell).
