Does the 07 5.3 Classic (early version) use a return fuel line? When I pulled the engine/transmission I got the harness, fuse box and fuel lines. There was 2 lines, but I am wondering if one is an evap line?

No, a 2007 does not have a return line, the second line is the evap and is hooked to the purge solenoid on top of the intake. You can just take the line off of it and leave the solenoid in to plug the hole since it's closed until you hook power to it, providing it's not bad and stuck open, which I've seen a few times.

Thanks ls1nova71 for he fast answer. Now I can use the Corvette regulator/filter and plumb my 3/8 fuel line.
