Should vacuum reservoir hold vacuum?

Should the vacuum reservoir hold a vacuum? Sounds kinda stupid, I know. Own a '91 190E 2.6 and I'm trying to restore proper HVAC. Also, where is the darn vacuum resevoir??
I see the line running from the check valve on the left side of car to the right side behind battery and then disappears.

I've got the WHOLE dash off because I thought I had two bad vacuum actuators. Now, after removing the whole dash, I'm thinking they're ok.
The two I thought were bad are dual ported or 2-staged. They're the defrost and recirc./freshair. If I disconnect 1 line at a time they don't hold vacuum but if I disconnect both and put finger on one and evacuate the other, the actuator holds vacuum. Is that right?
