Abstract: A sump space unit for dewatering fuel in an underground fuel storage tank includes fuel filtration, coalescing, and water separation with water storage. The system includes a) a housing configured to be placed within a fuel delivery sump space above an underground fuel storage tank; b) A particulate media element within the housing; c) A coalescing media element within the housing; d) A water separation media element within the housing; and e) A water/fuel storage area within the housing. In one operational mode the flow is directed through at least one of the particulate media element, the coalescing media element and the water separation media element. In one operational mode the system receives water from the underground storage tank into the housing bypassing each of the particulate media element, the coalescing media element and the water separation media element.

Abstract: A high pressure filter assembly with minimal pressure drop includes a filter assembly with a cylindrical filter element housing having a central inlet at one end and an angled peripheral outlet on an opposite end, and an inside-out flow filter element coupled to the inlet having a lower endcap and an upper endcap assembly and filter media extending between the upper endcap assembly and the lower endcap, and wherein the upper endcap assembly includes an upper end cap and a diverter plate coupled to and spaced from an upper endcap of the upper end cap assembly with at least one vertical strut, wherein the diverter plate is angled in the direction of the angled peripheral outlet in a centerline plane of the peripheral outlet.

Abstract: A filter assembly with an authenticating filter element coupling, formed of the combination of a keyed bushing and locking guide, and replaceable drop-in twist locking filter element therefor. The keyed bushing is coupled a housing of the filter assembly and provides an authenticating mechanism for a replaceable filter element suited for the specific housing wherein the keyed bushing forms ½ of the authenticating coupling for the filter assembly. The locking guide is coupled to an endcap of a filter element and has a sleeve with slots in an end thereof that match keys of the associated keyed bushing on a filter housing. The locking guide forms ½ of the authenticating coupling for the filter assembly.
