ABSTRACT:
A filter element for use in a pan, such as a oil pan for a vehicle transmission or internal combustion engine, is configured for positioning in the opening of a sump in the pan. In order to position the filter element, an inwardly projecting shoulder is provided on the wall of the sump upon which a shoulder on the frame of the filtering elements rests. Between the two shoulders a resilient seal is positioned and held compressed by a latching arrangement on the filter element. A preferred latching arrangement comprises plurality of detents that project laterally from the filter element frame and seat within indentations in the wall of the sump. Preferably, the filter element has a pleated filter media.
