how the ls1 fuel pressure regulator is on the fuel rail correct. i didnt thing the rails where interchangable between the ls3 and ls1/6

Do 98 F-bodies run a return style fuel system? My 98 vette does and I run an Aeromotive FPR. I believe it is an A1006 with FAST fuel rails.

Hey guys I did an ls3 swap on a 1999 trans am with what it seemed to have had a returnless ls1 fuel rail with a built in regulator (I just read that my car has the regulator on the tank ? I am confused because there is a fuel cap canister with a return line on my car
My car is dumping fuel out the exhaust (it did that before the swap which lead to ruining my ls1 block within minutes after rebuild) now if I don't have a regulator on the tank them I'm guessing the regulator causing the issue... But if I do have a regulator built in the fuel pump then I have another issue causing my engine to run rich on fuel (fuel pressure stays between58-60 psi and is steady
