The vacuum pump, reservoir, and gauge arrived this week. After a trip to Menards for some gas fittings, I was able to test the system as a complete unit before putting into the car. Here is a quick video of the completed contraption. It takes about 2 full minutes for the pump to reach the shutoff point with the reservoir attached. It turns out the pump has an automatic shut off at 10 in Hg so I don't need the additional vacuum switch.
