A system and method for removing liquids from engines, the system including first and second liquid storage tanks that are disposed for serial flow therebetween, a pressure source, and a vacuum source. The first liquid storage tank is continuously connected to the vacuum source, while the second liquid storage tank is alternatively connected to either the vacuum source, during filling, or the pressure source, during draining. Opening and closing the valves is controlled in response to sensed liquid levels in the tanks.
