I based my supply and return lines on what Aeromotive suggested on their website. They have diagrams for all their pump and regulator combos and for EFI vs carb etc. They recommend the 10 AN supply and 8 AN return.

I figured it would better to be slightly oversized than undersized when it comes to fuel delivery. I was planning on using a fuel cooler on the return side, but wanted to hold off on the controller for now at least. I may go EFI in the future too.

I contacted Americam Autowire and they suggested I have the relay near the electrical supply... ie. not way back by the pump. My trunk is all boxed in with my stereo stuff etc, so thats why I was considering mounting it under the car rather than in it..

I rewired my entire car with an American Autowire universal 18 circuit system so it already has a supply off the fuse box for an electric fuel pump etc.
