1. A filter system, comprising:
a filter housing including:
a bowl configured to house a portion of a filter cartridge, the bowl having a first end, a second end, and a groove defining a bearing surface disposed at or adjacent to the first end;
a head configured to mate with the bowl, the head including an inlet to receive a flow of fluid into the filter housing, and an outlet to release the flow of fluid from the filter housing; and
a lever disposed on the head, the lever configured to selectively secure the head to the bowl, the lever configured to rotate between a locked position in which the bowl is prevented from being removed from the head, and an unlocked position in which the bowl is free to be removed from the head;
wherein the lever includes a cam surface configured to contact the bearing surface of the groove on the bowl when in the locked position, and the cam surface is configured to disengage the bearing surface of the groove on the bowl when in the unlocked position, and where rotating the lever upwardly by approximately 90 degrees in a direction toward the head and opposite to the bowl moves the lever into the locked position.
