The hose has been cut short, but it really isn't needed. It helps open the stove damper in the snorkle inlet to let in hot air from the stove on the exhaust manifold. It uses carb vacuum to do this, so the hose would have to extend to one of the ports on your carb. Unless you have a vacuum leak, that port has probably already been plugged. You really don't want hot intake air anyway (they did this for emissions and cold-start conditions), since a cooler, denser intake charge delivers better performance. I've been running my '80 without that plumbing for 13 years. If you still have the stove attached via the flex duct, it will pass a visual emissions inspection.
In the picture, the flex duct from the stove is obscured by the fresh air ductwork, but it is there.

Y'all two keep each other out of trouble up there, okay?
