A filtration system interconnection structure having a filter manifold including a sump housing and a first correlated magnet located on or connected to a portion of the manifold, and a filter cartridge including a filter media, first and second end caps sealed to the filter media, and a second, paired correlated magnet located on or connected to the filter cartridge housing body. The first and second correlated magnets are interconnected via magnetic communication upon insertion of the filter cartridge into the sump housing, and upon movement of the filter cartridge into an alignment position, the correlated magnet located on or connected to the manifold is permitted to translate as a result of the magnetic communication. The polarity profiles of the paired correlated magnets are aligned such that a repulsion force is created when the filter cartridge is inserted within the manifold sump housing.

A filter for filtering hydraulic fluid in a hydraulically actuated fuel injector. The filter includes a first disc structure and a second disc structure disposed axially spaced apart from the first disc structure. The second disc structure is also disposed parallel to the first disc structure. The filter further includes an intermediate structure extending from the first disc structure to the second disc structure. The intermediate structure includes a first surface and a second surface disposed opposite and parallel to the first surface. The intermediate structure defines a plurality of passages extending from the first surface to the second surface. Each of the plurality of passages is perpendicular to a longitudinal axis of the filter.

A liquid filter cartridge is provided. Preferred seal arrangements are provided, to provide for preferred axial load conditions, with respect to one or more of the end caps of the cartridge. Some cartridge configurations provided include no core structure or outer liner structure therein, to support axial load. Assemblies using the cartridge, and methods of assembly and use, are provided. The liquid filter cartridge can be a serviceable cartridge, or it can be retained permanently in a housing.
