JohnTeee Posted January 10, 2012 Report Posted January 10, 2012 I've been following the current fuel pump thread with interest. I have two, unrelated to each other, fuel pump issues. In the course of my recent exploits, I replaced the fuel pump. Turns out the problem was in the tank, which I just back yesterday and plan to put back in today. Now I have a fuel pump that still has some life in it, that I want to carry for a spare. What 'prep' would be good for long term storage to keep the membrane intact? Dad (out in SoCal) is getting his '48 going again. He replaced his fuel pump also. He and my brother were having some trouble getting it back in. I believe this is one of the NAPA replacements. The pump arm of the new pump has something of a 'shoe' or cap on it; saw that on my new one. They elected to take that cap to the grinder to reduce it a bit and got it to go in. I suspect that this is the root of his, now, not getting enough 'get up and go' and choking out. I'm going out there next week to visit and help with trouble shooting. I'm thinking they 'ruined' the new pump, but maybe we can swap parts between the old and the pump and make something that works. Any ideas on either of these? Cheers! John Quote
Labrauer Posted January 10, 2012 Report Posted January 10, 2012 On my 48 plymouth the fuel pump has a straight piece that goes on the cam. Now I had a 52 ford truck that had a little cup like thing on the end that went over a rod in the engine. I have never heard of one on a plymouth before at least not on a 218ci engine. Larry Quote
Plymouthy Adams Posted January 10, 2012 Report Posted January 10, 2012 one would want to orient the lobe on the cam that actuates the pump lever to be on the low spot when inserting the pump arm..that way there is no strong spring pressure to overcome aligning the pump mount bolts to their respective holes..could well be now that though the pump is working allbeit the actual travel is less and thus is the deliverly of fuel also less..

JohnTeee Posted January 28, 2012 Author Report Posted January 28, 2012 Just went out to visit my dad and we worked on his '48 P15. Turns out that whatever grinding was done on the fuel pump lever had done no harm. Did a little 'pee' test and it pumped several ounces out into a container in short order. Rebuilt his distributor, as it was not advancing correctly and replaced the vacuum advance he had removed years ago. Also not the problem. Problem actually turned out to be one of breathing. Dad had modified his air filter to accept a cartridge. The cartridge was a bit shy in height and there was not enough room between the base and the lower lip of the cover to let adequate air through. He now has a wood ring to lift up his cartridge and lift the top. So, no thoughts on storing a used fuel pump for a spare??? Cheers! John Quote
