Vacuum can hoses

I have a 1973 F100, when I turn the heat on it only blows on defrost. I know this means I have a leak so I looked and one of the hoses coming out of my vacuum can is just suspended and doesnt plug in anywhere. where does it go?

The vacuum reservoir should have two lines going to it. One should go to the intake manifold, the other passes through the firewall and goes to the HVAC control on the instrument panel.
