Shown is a used 120VAC Gast (brand) medical pump (pressure or vacuum) set up for vacuum. The first several plastic bottles I tried collapsed, then came the idea of using a dead fire extinguisher bottle. Rubber stopper is generic rubber stopper from hardware store. Drill two 1/4" holes in the stopper and insert the two pieces of "ice maker" hose. I've been vacuuming liquids out of engines, brake fluid reservoirs, transaxles, etc, now for 5 years. I'm on my second rubber stopper. Total cost was under $30.
Hope this helps.
