Have an interesting issue with vapor lock, when I have a full tank of gas car runs great with no issues, as it gets down to just less than a 1/2 a tank I start having vapor lock issues. The problem isn't continuous driving and running the tank down and than having issues, I'll have the car out than put it away take it out again and when after several weekend run and it gets down to the 1/2 tank level the vapor lock issues start. I just installed an insulator gasket and insulated the fuel line and the dual feed lines, it has helped but now the problem starts when it's down to a 1/4 tank. The car has an external electric fuel pump, 1/2 inch braided lines, and a fuel regulator (no return line), would changing the fuel regulator to one with a return line solve the problem?
