The return line from the pump to the tank is a whole different issue from a vented tank. I'm curious though, was it an a/c car originally? 2 or 4 bbl? Just trying to figure out application for the return line.
Bob- I don't understand the purpose of the return line. I mean, I get the part that fuel is returned to the tank. But why is it returned to the tank? Did the pump build up excess pressure which could damage a carb? Or blow out the pump? Vapor lock? Can you give me the two minute primer (pardon the pun) on the purpose of the return line.
