fuel lines

[31-5window]

Need some help with fuel lines i have a basket case here and don;t know where anything goes. I have what ever you call the thing in the bed by the filler that has three lines coming out of it. there is no steel lines on that side. then up front looks like a vent line where do these lines go?

The thing with the three lines is a "vapor/liquid separator". The two vent lines (one from each side of the tank) go to it, and the third line goes to the front to a vapor canister and then to the carb. Without the separator, liquid fuel can dump from your vent line. This diagram (which I saved from somewhere I can't remember) shows the plumbing. I don't know much else.

Find and purchase a factory service manual, worth it's weight in gold for these old trucks.
