Abstract: A filtration system having an undulated interlocking housing-endplate interface geometry is described. In the filtration system, a filter element endplate and a filter housing component (e.g., a shell housing, a filter mounting head, etc.) meet at an interface. The filter housing component includes an undulating or repeating pattern that meshes with a matching undulating or repeating pattern on the endplate of the filter element. The undulating or repeating pattern prevents the filter element from freely rotating with respect to the filter housing component of the filtration system.

Abstract: A variable efficiency filter media. The variable efficiency filter media is a composite media formed of at least two different types of filter media, such as standard efficiency media and high efficiency media. The variable efficiency filter media has at least two different efficiency levels. The different efficiency levels can be spread across different zones. The filter media types for both the standard and high efficiency media can be spun media, melt blown media, nanofiber media, micro-glass media, cellulose media, carded staple fiber media, and the like. The variable efficiency filter media may be produced by any of an air laid or wet laid process.

Abstract: A fuel filter assembly for filtering a fuel-liquid mixture comprises a filter cartridge and a return tube. The filter cartridge comprises a filter media and a housing. The filter media defines an open central region therein. The housing contains the filter media. The return tube extends into the central region of the filter media. The return tube collects and drains liquid from a bottom inner region of the filter media.

Abstract: A no filter no run (NFNR) fluid filter and fluid filter assembly are provided. The NFNR fluid filter assembly includes a fluid filter, a filter head or filter housing, and a bypass flow path. The by-pass flow path may be sealed off when a compliant filter is installed (a filter without a bypass seal), fluid may flow to the bypass flow path.

Abstract: One embodiment is a filter element including an outer filter media and an inner filter media. The outer filter media is operable to remove particulates present in a flow of fluid and/or coalesce water contained in the flow of fluid. The inner filter media is operable to remove particulates from the flow of fluid, separate water form the flow of fluid, and remove particulates from the flow of fluid. Other embodiments include unique apparatus, devices, systems, and methods relating to fuel filters and filtration. Further embodiments, forms, objects, features, advantages, aspects, and benefits of the present application shall become apparent from the detailed description and figures included herewith.

Abstract: A fuel water separator filter is described that is configured as a filter-in-filter construction with multiple water separating layers to separate water from the fuel. The fuel water separator filter is configured for use on a suction side of a fuel pump, and includes a neck with a radially outward facing seal that in use seals with the filter housing. The filter housing is formed with an isolated water sump that in use is isolated from water that is stripped from the fuel by the first stage of the outer filter. The isolated water sump is formed by a wall within the housing, instead of relying on an outer diameter seal on the filter to form the water sump.
Abstract translation: 描述了一种燃料水分离器过滤器，其构造为具有多个水分离层的过滤器过滤器结构，以将水与燃料分离。 燃料水分离器过滤器构造成用于燃料泵的吸入侧，并且包括具有径向向外的密封件的颈部，所述颈部在使用中与过滤器壳体密封。 过滤器壳体形成有隔离的水槽，其在使用中与通过外部过滤器的第一级从燃料剥离的水隔离。 隔离的水槽由壳体内的壁形成，而不是依靠过滤器上的外径密封件形成水槽。
