new here. vacuum line question

[supermanprime]

I have been workin on my friends 2000 valk, it was in an accident and we needed to do an engine swap. i figured out most of the hoses through here, however I am still unsure on the tank vent tube. from what I have read here the line that comes from the #6 carb goes into the thin opening on the petcock right? where does the tube that goes into the rear center underneath the tank go or come from? my friend just digged into it without taking note where the lines came from and went. thank you. the green str goes into the petcock fer fuel, the blue strs into the airbox , the clear one isn't showin  but I know that already. the red ones go into the 2 holes in the chrome bracket(do they just hang there?) the one from #6 carb isn't showing in this pic. i just need to know about the rear vent on the tank, also do the red stars just hang?or do they connect to something, thank you, great boards by the way.

The tank vent line goes behind the center cover.  There is a Tee halfway down the line.  The perpendicular leg doesn't have a tube attached.  It's there in case the lower tube get's plugged.
