Ideally the return would originate at the fuel rail. On most cars (including all LS1 F-Bodys) the return line has been moved out of the engine compartment to reduce fuel heating and evaporation. LS1 Corvettes had return from the fuel rail in 97 and 98.

I dont think any of them do...But you can just install one if you'd like.

97-98 Corvettes have them at the fuel rails and some trucks. The F-Bodies never had return lines at the rails.
