It is my understanding that all fuel systems with a return system will have a larger inlet fuel line and a smaller return fuel line. On my 99 SVT I have at least the large inlet and smaller return. Also the return line generally (not always) comes off the fuel rail at the fuel pressure regulator.
Things may have changed, but look for the two different sized lines coming off the fuel rail.
You may have to pull the upper intake plenum from the car to be sure, but that is only 6 bolts, the egr, some hoses and throttle cables or T-body.
