I am trying the vapor lock solution that was suggested by Michael Morton a while back. Like him, I had my Q-jet filter housing modified with a return line outlet at the top of the housing. My mechanic drilled, tapped, and soldered in a fitting to attach a return line to the gasoline filler pipe. I then had him tap into the filler pipe and run the line for me. I would have done that part myself but for having wrist surgery about 6 weeks ago making me unable to use my right hand fully.
The theory is the same as using the three port mechanical fuel pump or a three port filter, but it eliminates any deadhead all the way to the carb. Michael said this was the thing that FINALLY cured his vapor lock issue. I'm hoping for the same results, having tried everything else, but in tank pumps.
