3 fuel lines WTH?

I'm getting to the fuel side of my swap and I have 3 fuel lines coming out of the engine what is what? I've read about return lines but only one. I have 3 lines that run to intake from rear of jeep. This is a 5.3 supposed to be from 04 suburban but wiring harness has blue and red connectors and get.

One is probably the evap line from the gas tank to the intake.

Oh OK. Makes sense. Should I tee it in with return line? Or do away with it?

EVAP can be removed if you don't have to pass emissions testing. If you keep it, it does not connect to the other lines in any way. It vents the fuel tank vapors to the intake manifold.
