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 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.
