Happy Thanksgiving everyone!! Very happy this year for everyone’s advice I have gotten throughout my Coronets restoration. My car is finally running good after battling issues with brakes, transmission linkage and leaks. I also tuned it and at 16 degrees BTDC I have 20 mercury inches of vacuum, idling at about 650 rpm. My issue is that every now and then I have an extended crank before it starts. Initially on the morning it starts great, but then I have to pump it a little to get it started. Not a big issue but it’s getting annoying. I upgraded to an edelbrock four barrel with matching intake and installed a bypass fuel regulator but have not done return line. I am now seeing all signs for vapor lock with the head end setup. Bubbling in the filter and hissing when I remove the gas cap. What is the best routing for a return line? My plan is to come off the pressure regulator with a 1/4” fuel hose an maybe run along the side supply line. I also found a fitting on Amazon that I am thinking about installing onto the fuel sender. That way I can remove the sender and not worry about shavings falling into the tank. What do y’all think? Any recommendations?
