It is the Air Injection Reactor valve. It controls the air from the air pump .the valve can either dump the air in the exhaust upstream at the exhaust manifolds or down at the cat.Chances are the air pump is gone, as well as the AIR tubes at the manifold. Does it have a cat?

the small hose was for the solenoid that controlled the vacuum. You should try to find a vacuum diagram for it. I dont recall the intimate details, but it has a solenoid to control vacuum, turns on only when engine is warmed up to operating temp, and it could have one to switch the valve from upstream to downstream, or vent to atmosphere as well.If you look at the part closely,it may have some markings on it that can help you figure some of it out.

Those had some sort of check valves if I remember and when they went bad the hot exhaust would get to the plastic valve and melt them

About the only thing needed from the sound of it, would be to bypass the air pump by putting a shorter belt on the engine.If your state doesnt require emission testing, let it go. Otherwise you can get an aftermarket cat, and all the goodies to put the A.I.R. system back together.

I found myself in the same situation. Redo some 30 year old emmision system for what ever thats worth. Or simple plug it and run just as good. If your are trying to keep things stock/original then redo it. Or simply plug it but leave it in place. With weight savings, extra load on the motor, and clearing up clutter so the engine especially around the carb can have cool air flow I have started to remove some things.
