Name this part please

This is a broken vacum line that i can hear hissing when I turn off my truck, id like to replace it but i have no idea what it is. It is on the passenger side towards the back, and is located right around what I believe to be some sort of AC component. Any help is appreciated.

Picture's not very good and it would be better if not so close. But since it is just a vacuum line can't you just buy some bulk line from auto parts and replace it?

the part with what looks like a shoe string on it, is a ported vacuum switch, what the hose is broken off of, I don't see in the pic...

Looks like the line that leads into the HVAC controls?

I figure it is probably for the blend door, judging by where it enters the firewall, but the pic sux.

I looked at my parts B-II, and it IS the one-way vacuum switch on the B-II it mounts on the vacuum reservoir to let vacuum build, but mot let it escape. This promotes proper vacuum at all times during engine operation, so that things like the blend door switching to defrost at different throttle positions, does not happen.
