Abstract: A fuel water separator filter that is configured as a filter-in-filter construction with multiple water separating layers to separate water from the fuel. The fuel water separator filter is configured for use on a suction side of a fuel pump, and includes a neck with a radially outward facing seal that in use seals with the filter housing. The filter housing is formed with an isolated water sump that in use is isolated from water that is stripped from the fuel by the first stage of the outer filter.

Abstract: A filter assembly that comprises a housing, an outer filter element, and an inner filter element. The outer filter element is positionable within the housing and comprises an outer filter media. The inner filter element is positionable within the outer filter element and comprises an inner filter media, a media support structure, an inner top endplate, and an inner bottom endplate. The inner top endplate comprising a top rib that extends continuously around a portion of a top surface of the inner top endplate.

Abstract: A filter cartridge for use within a filter housing of a filter assembly that includes a filter media, a first endplate attached to a first end of the filter media, and a second endplate attached to a second end of the filter media. The second endplate includes a plurality of extensions extending axially away from a surface of the second endplate. The plurality of extensions possess a toothed profile and are sized and positioned so as to engage with at least one rib associated with a portion of the filter housing such that, when at least one of the plurality of extensions is engaged with the at least one rib, a rotation of the portion of the filter housing in a first direction results in a corresponding rotation of the filter cartridge.

Abstract: Various embodiments disclosed herein relate to a filter element having a seal that functions as an anti-drain seal. The seal prevents fluid being filtered (e.g., fuel) from flowing back to a fluid storage tank (e.g., a fuel tank) through a drain in the filter housing when the filter element is in an installed position within the filter housing. The seal and the filter housing allow fluid to flow back to the fluid storage tank when the filter element is being removed from the filter housing (e.g., during a filter change service). The seal is removably coupled to the filter element such that the seal can be reused with replacement filter elements. The seal also functions as an engine integrity protection mechanism. Thus, the seal performs functions as a sealing device, draining device, and engine integrity protection feature.
