Has to have return line, We used an Aeomotive regulator, here's a pic of the PCM harness entering the bay and exits to wheel well behind regulator, fuel lines all route through the regulator, find a good place to splice to the existing fuel lines or run new, the fuel connects to the fuel rail as set on the drivers side.
Ok I'll do the same then. I have nothing so I'm starting from scratch as far as fuel system goes I'm buying Aeromotive tank and every thing else that goes with it all the way up too the rails. I wasn't sure how you would route a return line to a fuel rail that is returnless . Now I see that the "return" line is routed thru the regulator. If I understood it correctly that is. Thanks guys! Learning quite a bit thru this thread!
