Does anybody have an idea on how to make a tiny little vacuum pump on the order

110, but I can rig up a 12 volt supply if necessary.

The reason I say this is that I'm getting ready to pack a fairly large number of
bags with used but serviceable engine parts (valves, pistons, etc.) and I'd like
to put each part in a "baggie" (sandwich bag or equivalent) along with a little
preservative oil, and then suck the baggie down with a football needle stuck
into the top closing mechanism just before sealing.

Thoughts?

If it is just the suck that has to be tiny and not the pump, how about
a toilet paper roll and some duct tape to make an adapter to your shop
vac?
