Im not afraid to admit I just don't understand the theory of how the vacuum pump and booster system work in a normal relationship. So thank you for your patience. If I was to take the one and only line coming off my vacuum pump, and plumb in a small closed reservoir, would there be any ill effects on the pump?

I guess what I'm saying is I can see the reservoir filling with vacuum, but at some point, it will be full and as the engine runs will still produce vacuum. Would that reservoir need to have a implement that would allow it to vent at a certain vacuum pressure, or, will the vacuum pump just relieve itself keeping a constant pressure inside the reservoir?

I know Im not explaining this clearly, could one plug the vacuum port off the pump completely and suffer no consequence?
