My dirty collection pump,
as inspected by my cat. I buy an air powered pump. These things can pump about as much oil as you can supply them with air. The bus has an air compressor that does a whopping 15.5 cfm at idle. That means I can probably pull 15-20gpm at fast idle, maybe more.

Oops. The dirty filter as mounted
