I have other questions but I thought I'd better pace myself.

I was told that I don't need a fuel return line but I'm not so sure I agree. I have an Edelbrock Perfomer 600CFM carb, a Holley Blue fuel pump and regulator, as well as a filter and I'm gonna install a shut-off valve (as per Dave's advise on another post that I never would have thought of) and 3/8" lines.

I want to plumb the hard lines before I get my body on so should I run two or is just the supply line required.

Thanks,
Sean
