Tiny vacuum pump

Does anybody have an idea on how to make a tiny little vacuum pump on the order
of an aquarium pump or so that will draw just a few inches of water? Preferably
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?

Because the pump has to fit on a bench that is already overcrowded. If I was
going to use a shopvac, btw, it would be with a pvc waterpipe fitting glued to a
barbed fitting with plastic tubing. I thought of that and then the hassle for
each part of reaching down to turn the vacuum on for each part you want to seal.
