ABSTRACT:
In an oil pump inlet screen assembly adapted to be immersed in an oil pump and comprising a filter screen including a housing and a lift pipe adapted to be inserted at one end into an oil pump opening, the improvement wherein the housing and lift pipe are molded integrally of plastic material, and wherein the screen assembly further comprises a metal eyelet received over the pipe end and adapted to be press-fitted into the pump opening. The eyelet includes coaxial cylindrical portions respectively disposed internally and externally of the pipe end and an external flanged end portion which captures a circumferential rib on the outside of the pipe both to retain the eyelet on the pipe end and to function as a stop to limit press-fit insertion of the pipe end into the pump opening.
