Been messing around, and today took a $12, 12V tyre pump, and converted it into a vacuum pump.
Pulls and holds 25" Hg, which isn't bad as we've only got 27" or thereabouts to play with (story for another day there).
The piston seal is angled the wrong way, and obviously I haven't run it on something with volume.
But will be useful in my refilling single use camping bottles, and maybe brake bleeding and the pile.
