ABSTRACT:
A filter assembly, filter element and methods are provided. The filter assembly includes a filter base in which a filter element is mounted. The filter element includes a bypass valve carried by the filter element that operates independent of and free of interaction with the filter base. Methods include providing an entirely new bypass valve for the filter assembly by inserting a filter element including a complete bypass valve into the filter base such that bypass valve structures of the filter base are rendered useless or superfluous.
