Vacuum line-where does it go?

[btbiii]

I just re-assembled by intake manifold after replacing all of my coolant lines and plastic connectors. I have small diameter vacuum line that I cannot find the home for. It is connected to a tee fitting underneath the intake manifold. It appears to be long enough to go to the throttle body, but the only fitting on the throttle body that would fit this size, has a small length hose with an round block in connection, do not know if this supposed to be there or not. CAN ANYONE HELP? Thanks

Pictures would help.

Just a guess but I think its for the fuel pressure regulator at the end of the rail.

I added the line I found, and the throttle body. If you look at the throttle body it has a short piece of hose on a barb, but it is choked off with an L piece of round stock, like a round allen wrench. Don't know if someone broke this line off before and just blocked off throttle body. Intake was definately off before, as some left off the mounting bracket and did not have the mounting screws on the front and back side.

Take that homebrew rig off the throttle body and plug that line in there. That's where it goes. I'm not sure what it's attached to on the other end, but it's under the lower half of the intake manifold.

It appears to come from a T that comes off a check valve, another piece called a "container". I guess it fell off and some one got creative. When I took the intake manifold off, I found out that the only thing holding it on were the mounting studs to the head. The bottom bracket is MIA and the front and rear screws were not installed.
