So I'm wondering what it it. The gas cap warning kept coming on just before I tore into the truck again and when I pulled heads, I saw this extra hard line just hanging out uncovered. I just capped it for now. Is it a return line for the stock fuel rail? Or is it an evap emissions line? If return, I would need to mount a FPR and return ... right now it's just a dead head.

If your talking about the line that follows parallel to the fuel feed line it's your evap line, goes to the evap purge solenoid.

Wondering what to do with it. Can't really plumb it to the intake manifold due to the turbo setup now and don't wanna be putting pressure into the tank. Also see no connectors for a solenoid, I'm assuming that's at the tank?

I have mine to my intake, no issues here but if your concerned about it just delete it or put it to the inlet of your turbo. Been awhile since I have had a stock layout on the harness but should be off the driver side ignition harness on the motor.
