Abstract: A pump for use with containers with differential and transmission oil includes an adjustable collar for attachment to the containers, and a length adjustable casing to facilitate oil removal from the bottoms of the containers. The pump is manually operated and includes a flexible tube for delivery of the oil to a desired location. A bell-shaped adjustable collar facilitates an attachment of the pump to the top of the container, and an overflow line having a sight gauge can be used to determine when no more oil should be pumped to the receiving structure. Small baffles may also be provided interiorly of the pump casing to prevent solid residue and particles from being pumped into the differential or transmission of a vehicle. In a modified embodiment, the baffles comprise thin magnetized plates so as to be particularly effective in capturing ferromagnetic particles.
