Hello i'm just wondering if anyone knows off hand before I go pulling off lines on the fuel pump from left to right which port is the fuel send/delivery port on my pump there are 3 ports it's a 2000 LS 4x4 4 door with the 4.3. I think one is the send, one is the return and one is the evap. all info is greatly appreciated.

 

Pressure line is 3/8". Return line is 5/16". Vapor line is 1/4" and the connector is noticeably different than the pressure and return lines.
