Return Fuel Line? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Do I need a return fuel line? I'm ordering new fuel lines and am confused on whether I need the return line or not. The truck is torn down to the frame and I'm not sure I remember what all I removed... I remember taking off the fuel line and the vapor line, but I don't remember a return line. It's a 1972 C10 with a 307 v8.
Also - I'm going with 3/8" fuel line. I'm not sure if it was 5/16 or 3/8 before. Are there any concerns in case it was 5/16 before?
