I was a little surprised to see the prices of these vacuum pumps in excess of $100 so I figured I'd ask for a recommendation so I don't have to waste time and money to get a good oil vacuum pump. Thanks for your recommends. Primary use is for a Yanmar 3GMD
The best ones I've used personally are the OEMTools branded units. The hoses on them are easy to work with, they're durable, and they come in various sizes.
Our engine was fitted with a Banjo replacement sump plug piped to a pump. Oil is removed to discard containers in seconds. Probably about the same cost and a permanent zero storage solution.
