Abstract: A filter assembly includes a filter head and a filter cartridge. The filter head includes a filter head coupling surface, a filter head outlet, a filter head inner wall, and a filter head outer wall. The filter head coupling surface defines a filter head opening. The filter head outlet is configured to provide a fluid. The filter head inner wall extends around the filter head outlet. The filter head outer wall extends around the filter head inner wall. The filter head inner wall and the filter head outer wall collectively define a filter head channel. The filter cartridge includes a filter cartridge shell and a filter element. The filter cartridge shell has a filter cartridge coupling surface that is configured to be coupled to the filter head coupling surface. The filter cartridge shell defines a filter cartridge opening.

Abstract: A filter assembly comprises a housing defining an internal volume and comprising an inlet for receiving fuel, a first outlet to allow filtered fuel to exit the internal volume, and a second outlet to allow water separated from the fuel to exit the internal volume. A filter element is disposed within the internal volume for filtering the fuel to provide the filtered fuel and separate the water from the fuel. An outlet assembly is fluidly coupled to the first and second outlets and comprises a first flow path structured to communicate the filtered fuel to the first outlet, and a second flow path fluidly coupled to the internal volume of the housing and to the water reservoir so as to receive the water from the internal volume and communicate the water to the water reservoir. The second flow path is fluidly isolated from the first flow path.

Abstract: A liquid filtration system is provided. The filtration system includes a filter head and a filter cartridge configured to be removably coupled to the filter head. The filter cartridge includes a shell housing and a filter element. The shell housing defines a first housing end, a second housing end, and a housing sidewall extending between the first housing end and the second housing end. The filter element is received within the shell housing and removably coupled to the shell housing. The filter element includes a media pack configured to filter matter from a fluid flowing therethrough and an endcap coupled to an end of the media pack. The endcap comprising a retaining member engaged with the shell housing.

Abstract: A dual stage fuel water separator filter is provided. The filter includes a first stage and a second stage. The first stage includes a first media pack and a first coalescing wrap. The first media pack is coupled to a first upper endcap and a first lower endcap. The first coalescing wrap is coupled proximate to an inner surface of the first media pack and is coupled to both the first upper endcap and the first lower endcap. The second stage is positioned radially within the first stage and includes a second media pack and a second coalescing wrap. The second media pack is coupled to a second upper endcap and a second lower endcap. The second coalescing wrap is coupled proximate to an inner surface of the second media pack and is coupled to both the second upper endcap and the second lower endcap.

Abstract: Various embodiments provide for a filter assembly including a filter head having one or more filter head threads and a filter cartridge. The filter cartridge includes a shell having a shell wall defining an internal volume and a collar disposed around and coupled to the shell, and a filter element. The collar includes one or more collar threads threadably engaged with the one or more filter head threads. The filter element is disposed within the internal volume. The filter element includes filter media and a first endplate coupled to the filter media at a filter media first end. The first endplate includes an endplate end wall and a first spacing member. The first spacing member extends axially away from the endplate end wall such that the first spacing member spaces the shell away from the filter head when the filter element is installed in the shell.
