1980 Rod to Air Hose on Front Suspension

[shawn_fountain]

There is a rod going up and down from the center of the front
suspension that is causing air to dump when I do not want the air to
dump, or at least if I mess with that rod air stops dumping. Anyone
know what that rod is for, and if okay for me to just adjust it (up I
think) to stop the air from dumping out. I did have the bus on a
sloping street lifted high on the sidewalk side to make level, but I
have had intermittent large air leaks from the same place for a long
time.

Also, there is a junction of I think 3 air hoses near this spot.
Anyone know where these are going? I appear to only be using 2 of the
3, and the 3rd appears abandoned by a prior owner.
