I have a small block with a 3/8 pump and carb fitting. What year, model and engine should I use to get the right line?

Did any of the small block engines with single feeds have a 3/8 line? How much bending would be needed if I use a big block line?

You will have to go to a parts store and buy piece of fuel line, Bring your fuel pump and carb fittings to match them up. Make a template out of a piece of wire coat hanger to get a general idea for shape and length. The steel line is cheap. After you get it to fit the way you want you can paint it, polish it or like I did by a new piece of Stainless tubing and copy what you just made.
Good luck........

Thanks for the reply. I guess I'll have to go ahead and get a new bender, I don't have much luck with the one I have.
