Sorry to Hijack, but I have a related question. I'm running a 440 six pack that does suffer from vapor lock issues. I have an electric blue Holley pump regulated to 6psi.

I was thinking about using the stock fuel line as my return. Since I'm not running a mechanical pump at all, will adding the vapor separator (with .060" hole) help me???
