Hello everyone. I've read through the numerous threads on vapor lock, but couldn't find the answers I'm after. Working on a 70 dart swinger 340 car with a 1979 360 in it with edelbrock intake and carb. Car exhibits signs of vaporlock. I'm weighing either an electric fuel pump or a wix fuel filter with the return line connector. Leaning toward the return line and the wix fuel filter. My gas tank doesn't have a return line adapter so I have been looking at a new sending unit that includes the return line connection. Has anyone solved their issue with this approach and if so, which sending unit did you use?
Also, has anyone tried the hot rod sleeves with success? Wondering if this is worth trying first.
Thank you.
