Fuel line confusion

[mrbill426]

Looking at suppliers that sell restoration fuel lines, they all list main, return, and vent lines for our cars.  Best I can tell my '72 only has a 5/16" main (feed) line and a 1/4" vent line, and NO return line; does this make sense or am I missing a line?    

The 'Cuda was built in early April of '72; a 340 4bbl (steel crank), automatic, with factory A/C.  It has multiple vent tubes at the front of the gas tank that have hoses running to a "chamber" on the frame body, with a single line running from the chamber up front to the charcoal canister.  That vent tube "breaks" up forward with a short rubber line, then back to steel.  The fuel pump only has a line in and a line out.

Also, any feedback regarding ready-made fuel line suppliers would be appreciated.

Thanks!

You want to deal with FINE LINES INC...Your car should only have the two lines you described.

Correct, you should have a 5/16" fuel line and a 1/4" vapor line. The return lines are made for cars that run pressure regulators, handy if you've gone electric/aftermarket with your fuel pump.

I've got Inline Tube's 3/8" stainless steel fuel lines on a couple of my cars now, never had a problem with them.

Thanks guys, it is what I thought but based on the way they advertise the return lines as though they were a replacement i was not sure.

I have two supplier recommendations, what are the big differences?
