  • Patent number: 5879140
    Abstract: An oil pickup device is provided which is adapted to replace the standard oil pump cover plate and pickup tube typically utilized for use with a conventional oil pump for an internal combustion engine. The oil pickup device comprises an oil pump mounting section having a front wall which complimentarily conforms with the mating surfaces of the pump housing to provide an oil seal and for segregating the discharge chamber of the oil pump, and an oil pickup section for extending into the oil contained in the engine supply reservoir formed within a conventional oil pan to provide a continuous supply of oil to the oil pump. The oil pickup device further includes an oil filter or screen positioned between the oil pump mounting section and the oil pickup section for filtering inlet oil to prevent particulate matter, such as dirt or metal shavings, from entering into the oil pump.
