Other Vacuum sorce
Years ago they did not use vacuum pumps. I can remember the old cubs & stinsons had a cone shapped device on the side of fusalage that created a vacuum source with no moving parts to worry about. I think you can still get them. They would not work on the ground before take off. That would work once you got air born for emergancy use only.
