Hello everyone!! Sorry i’ve been MIA for a few months now! Its been too cold and theres been a lot happening in my life. Got fired from another job and i’ve not been in a great place. I am also now an adult! Besides that, I am doing better now so I figured i’d make my grand return with a question

Anybody know how to reassemble a fuel pump? Jim took it apart and now the diaphragm is all sorts of messed up. Neither of us know how to reassemble it properly, so if anyone has a video or some tips on what to do, please feel free to let me know ❤️

(Below is a picture of me with my new hat since I don’t have a picture of the pump on hand)

Cute photo!

While it’s apart you should put in a new diaphragm and seal kit anyway - one that can handle modern gasoline. If the diaphragms are old, they will fall apart using the old. The shop manual is available here on this site in the Literature Archive and shows good images, though a bit generic of an older model, of the fuel pump disassembly and reassembly (a capture is below) with some great tips that might not be too obvious just by looking at the pieces. However, most things can go together only one way so hard to go wrong but be sure to note that it is necessary to preload the diaphragm before tightening all the screws and how to do it is shown clearly in the shop manual so no need to repeat it here.

In the meantime, I have lots and lots of photos from recently rebuilding my own 1951’s pump but you weren’t too clear about where the confusion is so here are some at random. There were two different arm types so yours might not be the same as the closeup that I showed.
