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.

Abstract: A filter cartridge includes a shell, a connecting ring, an end cap, and an axially directed sealing member. The shell defines an inner cavity and an upper lip disposed along an upper edge of the inner cavity. The upper lip defines a channel. The connecting ring is positioned outside of the inner cavity and is engaged with the channel. The connecting ring includes a threaded region extending along a central axis of the shell. The end cap is engaged with the shell adjacent to the upper lip. The axially directed sealing member is positioned between the shell and the end cap and extends axially outward so as to form an axial seal with a filter head when the filter cartridge is installed on the filter head.

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 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 water drain valve system structured to drain water from a fuel-water separator. The system includes a collection vessel structured to temporarily store water, a liquid level sensor structured to monitor a level of the temporarily stored water, a drainage port extending radially from the collection vessel and having a port inlet and a port outlet, and a valve assembly. The port inlet receives water to be drained from the collection vessel, the water flowing through the drainage port and exiting through the port outlet. The valve assembly is movable between a closed position in which the port outlet is closed, and an open position, in which the port outlet is open, to selectively allow water to be drained from the collection vessel. The valve assembly includes a solenoid coupled to a seal member, the seal member closing the port outlet in the closed position of the valve assembly.
