Abstract: A filter assembly includes a filter housing, a filter housing lid, a filter cartridge, an endplate, and a seal member. The filter housing defines a first cavity and comprises a return passage in fluid communication with the first cavity. The filter housing lid is selectively coupled to the filter housing and defines a second cavity coextensive with the first cavity. The filter cartridge is positioned within the first cavity. The endplate is coupled to a first end of the filter cartridge. The endplate is configured to interface with the filter housing. The seal member is coupled to the endplate and is configured to be received in the return passage. The endplate is configured to partially separate the filter housing from the filter cartridge.

Abstract: A filter system including a designated filter cartridge having a geometric projection, a flow restriction valve that controls fluid flow out of the filter system, and a priming pump configured to prime the filter. The flow restriction valve includes an opening keyed to the geometric projection such that the geometric projection engages the opening and actuates the flow restriction valve. The flow restriction valve includes at least one fluid flow check valve configured to allow the priming pump to prime the filter system.

Abstract: According to a set of embodiments, the filtration system includes a housing with a fuel inlet and a fuel outlet. A pump is in fluid communication with the fuel outlet. A fuel tank is in fluid communication with the fuel inlet. A thermal recirculation valve includes a thermal recirculation valve inlet and a thermal recirculation valve outlet. The thermal recirculation valve inlet receives heated fuel and the thermal recirculation valve outlet is in fluid communication with the fuel tank. A fluid passage is between the thermal recirculation valve inlet and the thermal recirculation valve outlet. A passage blocking mechanism having a first position and a second position. The passage blocking mechanism is structured to prevent fluid flow through the fluid passage when in the first position. The passage blocking mechanism is structured to allow fluid flow through the fluid passage when in the second position.

Abstract: A filter system including a designated filter cartridge having a geometric projection, a flow restriction valve that controls fluid flow out of a filter system, and a priming pump configured to prime the filter. The flow restriction valve. The flow restriction valve includes at least on fluid flow check valve configured to allow the priming pump to prime the filter system.

Abstract: A filter including a shell with at least one viewing region, a translucent bowl that fits and is installable within the shell, and an attachment mechanism. The bowl is positionable within the shell such that at least a portion of the bowl is visible through the viewing region. The attachment mechanism securely attaches the bowl the shell together and prevents at least one of vertical and rotational movement between the bowl and the shell. The shell and the bowl are not threaded to each other.

Abstract: A filter cartridge including an improved endplate configured to enable a user to remove the filter cartridge from a shell without the use of external tools. The filter cartridge includes a filter media, a first endplate coupled to a first end of the filter media, and a second endplate coupled to a second end of the filter media. The second endplate includes at least one tab formed therein along an outer peripheral surface thereof. Each tab defines a pocket formed therein, via which the user may grasp the endplate and thereby remove the filter cartridge from the shell by hand.
