I have a 74 318 2bbl car and I want to order new fuel lines. They are asking whether I want the 3/8 line or the 5/16 line. I have a 318 V8, what lines do I need?
5/16 or 3/8 for fuel lines?

Factory would have been 5/16" BUT 3/8" won't hurt. Great if you want to upgrade.

If you are already replacing them 3/8. Except I bet the sending unit is still 5/16
5/16 would probably work for everything you would ever wanna do, but if I was replacing lines I would go with 3/8. That will sustain almost anything you would ever upgrade to.
3/8 sized fuel sending units are available.
I, myself, when doing this, upgrade the whole fuel line system to 3/8 in stainless steel. It's worth every penny.

Better listen to Rumble. That is what I've done on my dart.
Good question, good info.
It sounds like the consensus is 3/8" if you're replacing...
Where will you see the limits of the stock 5/16" lines though? Mine seem to be fine shape but they'll be feeding a bigger motor now. Until this thread, I had assumed they would be adequate.

Thanks guys, I will go the 3/8s route...
Show me where anybody said 5/16" would not be adequate. Nobody said or implied that. All that was agreed upon was that if they were being replaced anyway, to go 3/8".
