Carb fuel/vacuum line question. 81 750C

[Walt]

I'm putting the bike back together after having the carbs out to clean them. One thing I didn't take a reference pic for was the hose that comes off the "T" between carbs 2&3.
Any thoughts?

That is connected to a hose that goes over the air box and the bracket that moves the air box back and forth to remove the carbs has a U shape on the right side of it to keep the hose in place. Other than that it goes nowhere, no plug, just drapes over and down to about the middle of the air box. AKA, the hose to nowhere.

Without an air box I think I would direct the hose up above the carbs then let it point down, maybe under the tank.

Thanks for the help folks!
