KZ440 carb hookups

I'm in the process of tuning up my 81 KZ440 D2 LTD. When I was removing the gas tank I noticed that there seems to be 2 hoses running towards the petcock. One was hooked up to it, and runs to the middle of the carbs and I assume supplies fuel to both to both of them. The other was disconnected and runs to the right hand carb, and connects to it right before the inlet boot. There is a similar attachment point on the left hand carb, but it has a piece of solid rubber over it.

I can take a picture of it if need be, but I was wondering if someone could tell me what these hoses are supposed to go to, maybe someone has a picture of how all the hoses are supposed to be hooked up to the petcock? Thanks for any help.

Look at your petcock.
It should have 2 nipples,1 for to supply fuel to the carbs and the other to the vacume port.

It does, though before I removed the gas tank the vacuum nipple was not connected to anything. When I put it back together should I hook up the one hose on the right carb to the vacuum nipple and leave the other carb plugged? Or should I get a 3 way connector and hook them both up?
