I have a stock 1971 Cutlass Supreme, 350 2bbl, automatic, that is recently giving me fits with vapor locking in the past 4 years or so. For this reason it hasn't been driven much at all. I looked into the problem and realize the fuel system must be modified with a return line. My car does not have one presently. Bending a new articulated line looks like it would be a real pain to accomplish. My question is, can use the vapor return line for this purpose? What have you guys done? I already dropped the tank and I will buy a new fuel sender with the second line.
