Abstract
A device for removing oils, fuels and other fluids from reservoirs is disclosed that works in conjunction with engine-powered devices via a vacuum-actuated valve containing a multi-tiered U-groove. The U-groove allows a disconnection of the valve bolt shaft from the threaded end that fits inside the reservoir, trapping and holding the fluid in the reservoir.
