Fuel pump rebuild kit
Can someone point me to a rebuild kit for a 1954 239 yblock fuel pump? I have the original pump and i'm needing the kit, especially needing a diaphragm that will handle the unleaded gas these days.

It depends upon which factory fuel pump you have. The original Ford part numbers for the rebuild kits are B2A-9349-D and B2A-9349-E for the double and single action pumps respectively.
The single action pump I believe crosses with the airtex 4070 which is more likely to be economically available as a new E10 compatible pump. If you want to rebuild it, here is the supposed kit: https://www.then-now-auto.com/produc...fuel-pump-kit/
The double action I believe crosses with an AC 4052 with this rebuild kit available: https://www.then-now-auto.com/produc...fuel-pump-kit/

I would downright reject putting an electric pump inline with the mechanical pump. When (not if) the mechanical pump diaphragm fails, the electric pump will still pump gas and will now quickly fill your crankcase leading to what will likely be a very big repair bill. On a mechanical only setup when the diaphragm fails, so does the pumping action and thus the engine becomes starved of fuel brining everything to a stop allowing for the issues to be addressed before major damage. Sure, some creative with check valves and switches/interlocks, but why go complex and increase risks?
Commit to the electric pump (install it properly with an oil pressure shut off and/or equivalent safety gear) and remove the mechanical from the fuel circuit, or commit to the stock mechanical setup.

Try Cowboyjohnsautoparts It's in Florida. I had my power steering rebuilt a few years ago. He also does fuel pumps and has kits.

For those that need a fuel pump for a 239 OHV yblock, Napa has a replacement but you'll have to switch out the rod with the original one. The part number for the Napa fuel pump is mf0092. It's made by Delphi.

if that's the case, why not get one from auto zone for a FE 360/390 and change the arm. They fit right on a 55 and newer y block. I don't know the difference between a 272/292 and the early 239
