It doesn't have a return, so you'd have to fab up something. Unless your running nitrous, I think a high volumn mechanical pump and maybe a supplemental electric pump will be okay. I'm sure I'll catch heat for saying this, but I've gotten away with some pretty stout naturally aspirated engines running a 5/16" line and I never had fuel starvation problems. My .02 worth.
