Can someone with a factory 3rd gen TPI car please help me identify where the OEM fuel lines route to from the factory fuel tank?

I have converted to a carb and had the lines plugged before identifying which line went to what. Behind the rear driver side tire there are four fuel lines coming out of the tank. One should be the fuel supply to the rail, another should be the return from the rail, another should route to the charcoal vapor canister (I am really interested in this line), and the last should connect to an air intake valve right behind the tire (Looks like a mini UFO). A picture would also be really helpful!

Thanks in advance!!
