I used the Carter performance pump, and Hemi vapor separator, and did not have any fuel problems.
The reproduction vapor separator is expensive, I think $50, but it is setup for 3/8" lines. The fuel filters with vapor port I think are 5/16" fuel line, but only cost a few bucks. Really, you could just add a "T" to the fuel line before the carb, and install a restriction in the line that returns to the tank. You just want to maintain a minimum steady flow of fuel through the fuel pump and lines.
