Returning to thread...
Instead of buy a totally new electric vacuum pump, would converting the belt-driven pump to electric work? Would it be enough to take the belt off and attach an electric motor to it? If so, any ideas as to (1) how powerful the electric motor should be, (2) what rpm is best? I'm thinking that since the engine idles at 750-800rpm, the pump could be spun at no more than 1000rpm and still do its job.

The upside of this is that it could be wired to: (a) work when engine off coasting, and (b) slow down when there is enough vacuum in the system, reducing the load on the electrics.

What matters is where you're going, not how fast.
