ABSTRACT:
A fluid transfer system includes elongated conduits connected at one end with couplings to a plurality of fluid reservoirs of a machine or engine and at the other end with a control valve for selective quick evacuation. Evacuation is powered by a pump operably connected to the control valve. Another embodiment includes a first pump for the evacuation of an engine oil reservoir and a second pump for the selective evacuation of transmission and hydraulic fluid reservoirs. The control valve and the pumps may be operated remotely through electrical switches on brackets or on a service panel. Associated methods of removing fluids and replacing fluids from a plurality of reservoirs includes coupling the fluid transfer system to the reservoirs.
