A fuel water separator comprises a housing that defines an internal volume that receives a mixture. The fuel water separator further comprises a filter element that is positioned within the internal volume. The filter element comprises a first endplate and a second endplate that is located opposite the first endplate. The filter element further comprises a filter media that is coupled to the first endplate and the second endplate. The filter media is structured to separate a dispersed phase from a continuous phase of the mixture. The filter element further comprises a collection sump that is located below the first and second endplate and structured to receive the dispersed phase. The filter element further comprises a retention barrier disposed above the collection sump. The retention barrier comprises a drain opening structured to discharge the dispersed phase through the retention barrier into the collection sump.

Water retention barrier

A fuel-water separator includes a cartridge assembly and a bowl. The cartridge assembly receives a fuel-water mixture and provides a fuel. The cartridge assembly includes an endplate. The bowl is configured to store water separated from the fuel-water mixture. The bowl is coupled to the endplate. The endplate includes an air vent that receives air from the bowl. The air vent establishes a pressure equilibrium within the bowl and the cartridge assembly.

Fuel-water separator systems and methods

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.

Sealing systems and methods for a filtration system

Various example embodiments relate to a filtration system. The filtration system comprises a housing having a first housing end and a second housing end. The housing defines a central compartment therein. The housing comprises a key slot disposed on the first housing end and a housing key element protruding from the first housing end toward the second housing end. The filtration system further comprises a filter element positioned within the central compartment of the housing. The filter element has a first filter end and a second filter end. The filter element includes filter media and an endplate disposed on the first filter end. The endplate includes a central endplate opening, a key element configured for engagement with the key slot, and an installation guidance element formed along the central endplate opening. The installation guidance element is configured for engagement with the housing key element.

Endplate with guide feature

A filter assembly has a qualified filter element that filters fuel, a filter housing for the qualified filter element and a water-in-fuel sensor that senses presence of water in the filter housing. An electrical resistance of the water-in-fuel sensor changes based upon whether the qualified filter element is installed in the housing. A filter assembly can also have a plurality of magnetic elements disposed on at least one of the filter housing and the qualified filter element. A plurality of wires are disposed on at least the other of the filter housing and the qualified filter element. The control circuit determines that the qualified filter element is installed in the filter housing based on a change in the electrical current in the plurality of wires.

A connection between a fluid filter and a head is described that permits quick connection/disconnection between the two without requiring disconnection of fluid lines from the head. The head includes a lock to connect inlet and outlet fluid lines to a fluid filter using a non-threaded attachment method. The lock that retains the head to the fluid filter is flexible to allow for connection and disconnection. The head has fluid inlet and outlet ports to which fluid lines attach to flow unfiltered fluid into and filtered fluid out of the fluid filter when the head is connected to the fluid filter. The head closes the fluid filter, which has a protrusion with adjacent passageways that guide and separate unfiltered from filtered fluid.

Fluid filter and head with quick connector

A fluid filter includes a filter element having a filtering media disposed between two endplates. One endplate includes an open flow passage that allows a working fluid to flow into or out of the media during operation. The other endplate includes a connection structure. A cover houses the filter element, and has an opening that is an inlet or outlet in fluid communication with the opening of the one endplate. The cover includes another fill opening proximate the other endplate. A cap is connected to the connection structure of the other endplate to close the opening of the cover. The cover is retained between the cap and other endplate. Generally, the attachment configuration between the cap and the other endplate of the filter element helps ensure that the filter element with the correct micron rating is installed in a filtration system.

A valve assembly that is useable with a fuel filter housing to control the flow of fuel through the fuel filter housing. The valve assembly comprises two primary parts that are connected together via a snap connection, and when the valve assembly is installed on the fuel filter housing, means on the fuel filter housing prevent disconnection of the snap connection. One or both of the primary parts of the valve assembly can be provided with a tamper evident feature that will indicate whether someone has tried to remove or disassemble the valve assembly.
