My 1979 Z-28 Pro-touring car has a Supercharged small Chevy. I run 1/2 inch fuel line part hard line, part braided A/N lines. With a High volume Mechanical pump.You can either / or run an electric ,your choice. I also run a Holley regulator, and a fuel log Filters.I run around 15+ pounds of boost.500+ HP. But I tend over build things That way you are less likely to brake or hurt stuff.. Engines like this tend to be hungry. And they need on the rich side. 3/8 line is n`t enough ,I learned the hard way.There was n`t enough volume.Also included a picture of mine. But you can figure what will best works for your application. Good luck to you,
