Got a 2000 Silverado, originally had a 4.8L. Doing custom fuel system, removed all the factory fuel lines . Using factory fuel sending unit (except for the pump), but didn't pay attention to which line was which when I took it all apart. The main feed line is obvious, being the largest, and I think the return is the other outer line, assuming the middle line is the evap line. Am I right or is the center line the return?


I'm talking about the ports coming right off the fuel sending unit on top of the tank.
 
That looks just like the sending unit I have. Looks like my guess was correct, thank you, that's exactly what I needed!
