Got any pictures of it?
EDIT: On second thought, the only vacuum lines that run behind the manifold usually go to it. There should be a big one that attaches to a port on the elbow of the upper intake, then there should be another one that runs to a port underneath the upper intake, after a tee-connection. There should be 3 vacuum ports on the upper:
1) is the PCV, it runs from the PCV screen at the back of the lower, to the port underneath the upper, facing the passenger side of the car.
2) There is a fairly large line running from the vacuum tree to a port on the underneath of the upper, facing towards the rear of the car.
3) runs from the number 2 line on a tee-connection.
Good luck

The vapor purge solenoid will release stored vapors into the intake when conditions are appropriate. On my fox, the hose goes to the front of the upper intake (plenum), but space is tight on the 94-95 intakes right there, so it likely goes elsewhere into the upper (in the back). This is just my conjecture.
The vapor cannister should be in the pass fender if future issues arise.
A stockish motor should pull 15-20" hg of vac at idle. Below ~ 12" can affect the brake booster functionality.
A Miti Vac tool can be useful for finding leaks.
Good luck.

On the SN95s the EVAP canister runs to one of the two vacuum ports located on the underside of the upper intake manifold. The other connection under the intake manifold is the PCV line that runs to a "T" connector with the tube connected to the vacuum port of the lower rear plenum, and then on the throttle body elbow there is a small vacuum tree that has the firewall vacuum hose attached (the big hose), the fuel pressure regualtor, and the EGR vacuum source.
