I've got a question regarding fuel lines. My 69 has a single line. I've installed an electric fuel pump near the tank and was wondering how I would go about adding a return line. Is this a matter of adding a Tee and return line before the carb? Does the return line need to be a smaller line? I'm not sure how the pressure would be held constant a 7 psi without some kind of check valve. Any ideas?
