Dave,
Perhaps these photos will help you. The single Brass Fitting is the one I told you about in my first reply.
Flex Line I reused the original shut-off valve. I suggest you take your shut-off valve with you to make sure the threads match up. I used a fuel line from NAPA (Fuel Line Pump To Tank 5/16" X 60") P/N 813-5471. Good luck with you restoration.
