Thanks Riki and Jerome for the vital info here...

Bit of a correction here, fuel port on the carb is in the same place, but not the same size. It's 3/8 NPT (takes a fitting of .625 max OD).

So Gerry emailed me and mentioned that I'm actually missing the fuel filter, so I'm going to get one from him, question is that the carb port is 3/8 NPT when the fuel filter I guess is 1/8 NPT? A fitting like this would work, right?

Next question is what to about the fuel line by the old pump, looks like they stuck the old flex line right over the flange of the short metal line and clamped it. One question is if it's good enough, it doesn't seem to leak and IDK what pressure the fuel pump has. I would like to fix but I'm wondering how critical... For that, does anyone know how to install one of these? Is that a compression union or do I need to flare the ends? Would you trust a compression union?
