Need vacuum diagram/help for 2001

I am replacing some of the vacuum lines on my 2001 Astro since one was broken. While removing that one, another one broke, and I discovered a third one which was not attached anywhere. I don't know where this mystery hose should be connected. I looked around and could not find a diagram under the hood. I have a Haynes manual and it does not show a diagram.

I'll try to describe the mystery hose. First of all, there's a line that starts at the left valve cover, and is about 2' long and ends up at a T connection with a check valve in it. This connection is on the passenger side of the engine compartment and can easily be seen/reached from the front/top. The check valve is between this 2' hose and two other hoses, one short, and one long. The long hose was not connected to anything.

Thanks for the help.
