stupid fuel line question

[froggy]

HI on a 1977 (or similar model) fuel tank, where goes the fuel delivery line ? Middle on the driver side or bottom on the driver side? Thanks

On my '74, the middle line was the supply line, and the bottom line was the return. At least it was that way when I bought it, and it's still that way 15 years later. Not a stupid question.

Was there a return line in 1971?

No return line on '71. If I were me, with your setup, I think I'd plug the return line and make it as much like a 71 as possible, just to make life simpler. But I don't know enough about the later tanks to know if this could cause trouble.
