What is the correct fuel hose size going from tank to G2 fuel filter then to airtek electric pump then to supply line. I have 1/4 going from supply line under hood to the fuel rail.

I searched everywhere and cant find the answer. Right now I have 3/8 which is too big on those 3 sections.

Figured it out.

Its 8mm but 5/16 will work.

I was going to reply but I have EFI and you're running a carb fuel system. 5/16" (8mm) is right for the EFI system also.

It's not easy to get the hose clamped to the hard line without a lift, so maybe use marine grade USCG fire-rated hose, with a liner to prevent ethanol from wrecking it. Expensive but you don't need much. Might only need to do it once.
