I still use the old 5/16" fuel line up to the engine compartment, then 3/8" to the carb. With 7-8 psi at the carb, I seem to be OK without any fuel starvation. I have often wondered what would be necessary if It needed 3/8" all the way through.

I think the alteration of the sending unit that danford1 describes is what would work to get the larger line from tank out to the fuel line. If the '67-68 sending units are actually 3/8", then I guess I would just try to use one and then just run a 3/8" from there on up to the engine.

What I can't seem to remember is if your engine is carbureted or if it's efi ? If efi, then we would be looking at a more complicated problem.
