Vacuum line missing

My daughter has an "85" Bronco II with a carburated 2.8 V-6. There is a vacuum cluster under the back side of the carb with several lines going to it. There is a vacuum line missing on the bottom of the cluster for a small hose. Does anyone have any idea what might go there? I can't seem to find a vacuum line not connected to anything.

Any help from anyone who has the same settup would be really appreciated.

x2........Dura-spark it and never look back, the computer feedback 2150a carb and its associated vacuum lines are a nightmare. Once dura sparked you will notice power you never thought you 2.8 ever had.

It may be an unused vacuum port. Since you can't see any loose vacuum lines, plug it off for now(it may have had a cap over it that came off at some point).

I ended up having to rebuild the top end anyway. It's at the dealer having the rebuilt carb. tuned. I have done major engine work and 1 complete rebuild on 5 vehicles this summer. I am done working on cars for a while. Thanks for all the help.
