I am willing to do the whole system, just don't know what is involved. From what I can see, my biggest hangup will be the return line.
For a carb setup, the return line should not be needed if the electric pump is mounted aft in a cool location. Pressurized fuel from the aft mounted pump will resist vapor lock in the hot engine compartment... or will re-fill the carb bowl for start after heat soak boils out the fuel.
Your Holly should handle up to 7-9 psi fuel pressure. A self regulated pump in the 5-7 psi range, like the Carter street pump, mounted on a frame rail, should be fine without regulator or return line.
