Confused about fuel lines
I'm looking to replace the entire fuel system on my '67 GTO as part of finally getting the 400 back into the car.
The 400 currently has the later style fuel pump with the return port.
Looking at AMES, the gas tank kits they sell that use the vapor return all seem to be for 3/8" fuel line, but the fuel pump I have takes a 5/16" line.
What am I missing?
For reference, the parts I'm looking at ordering are:
N129C - 1967 4-BARREL FUEL LINE WITHOUT VENT LINE (RE)
L225N - 1966-67 GAS TANK KIT WITH 1/4" VAPOR LINE, 3/8"
1967 HARD TOP RETURN LINE 1/4" STAINLESS STEEL (RE)
N129PFA - 1967 HARD TOP FUEL LINE 3/8" STAINLESS STEEL (RE)
