What port is this? Kz750

I have been working on an ‘83 KZ750 twin, reconnecting all the open vacuum lines or capping them off. I found this open port between the carbs next to the fuel line input. Where should the line go connected to this?
Thanks.

That's an over flow tube that is supposed to run out between the frame and the swingarm.
You should have two of them.

Looks like a vent to me.

If they are the stock carbs then they are BS 34 carbs and have no overflow system. There are 2 tee ports between the carbs. One of for fuel inlet and the other is for carb bowl venting. This fitting should have a hose connected and run over the swingarm.

It should go up over the carbs and end on top of the airbox. Less chance for critters making a home in there and no negative air pressure to mess with the floats.
