  • Patent number: 5056621
    Abstract: A fluid transfer apparatus and method employing an electric pump with one discharge port and one or more suction ports connected to corresponding discharge conduit and suction conduits. By means of a switch, suction can be directed from one suction conduit to the other as required. The operator simply directs the flow of the contaminated oil to a suitable receptacle, energizes the system and provides suction on the oil pan through an oil plug adapter and old oil is removed. New oil is added by switching suction to another suction conduit and directing the discharge port to connection with an oil cap adapter so that new oil can flow through the discharge conduit into a vehicle through an oil cover adapter. Not only oil, but other automotive fluids can be removed and added to the vehicle by means of this invention. As a result, a safe and ecologically respectful and cost efficient means is provided for the transfer of automotive fluids into and out of a vehicle.
