Where does this EVAP Vapor Pipe at Fuel Tank go?

Hi,  I have (hopefully) a simple question about an EVAP system pipe, and any help would be appreciated. I have all other pipes identified (2000 GTP donor for homebuilt-reverse trike) but the smaller one nearest to the sending unit. I believe it comes from the Fill Limiter Vent Valve. Does it tee into the purge pipe to the engine, or is it for fresh air, or what? I've unsuccessfully scoured the internet and two different GM service manuals for the answer. I did find one picture of the line but it ends in dead space with no indication of where it connects to. It's labelled "1" in the picture and referred to as "vapor pipe". It's the second pipe from the top in the other picture. The links to the pics are below.

 

Thanks, 

Aaron
