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.

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 cartridge comprises a filter housing having a filter element disposed therewithin that comprises a filter media, and an end cap coupled to a top end of the filter media. The top end is positionable proximate to a filter head. A filter element outlet conduit extends from an inner rim of the end cap towards the filter head and is extendable into a filter head outlet. An end cap ledge extends radially outwards from an outer periphery of the end cap. A first sealing member is disposed at least partially on the end cap ledge and forms an axial seal with the filter head, and a second sealing member is disposed around the filter element outlet conduit on a radially outward surface thereof, and forms a radial seal with a radially inward surface of the filter head outlet conduit when the filter head is coupled to the filter cartridge.
