I'm seeing the walbro fuel pump and mallroy regulator as popular choices with boosted setups. What size fuel line would this system run? Does it require a return line? And do you run a stock fuel pickup or a custom setup considering the inline fuel pump?

No matter how ugly a turbo or sc looks I think they are flat out amazing to look at once they're strapped to a huge motor! Good work!
