摘要： It has been discovered that the function of a fuel filter monitor can be accomplished without the use of SAP. The present invention provides a fuel filter monitor comprising an ePTFE membrane, a support structure adjacent to said ePTFE membrane wherein the membrane is disposed upstream of the support and said monitor prevents penetration of water to the downstream of said fuel wet monitor, where the water can be in the form of discrete water drops in the fuel, or a bulk water stream which displaces the upstream fuel.

摘要： A filter element may include a first end cap including an end cap barrier including an inner end cap aperture and end cap flow passages configured to provide flow communication between the of interior the filter element and the exterior of the filter element. The filter element may also include a first tubular member having a first end coupled to the first end cap to provide flow communication between the inner end cap aperture and a second end of the first tubular member. The filter element may further include first filter media extending around the first tubular member, an intermediate barrier coupled to a second end of the first tubular member, and second filter media having different filtering characteristics than the first filter media. One of the first filter media and the second filter media may include a coalescing-type media configured to promote separation of a first fluid from a second fluid.

摘要： A filtration assembly filters diesel fuel used by a diesel engine and includes a filter element disposed within a housing. The housing includes an unfiltered fuel inlet and a filtered fuel outlet. The filter element disposed within the housing receives fuel from the fuel inlet. The filter element defines a peripheral wall sealably engaging filter media defining an unfiltered side and a filtered side of the filter element. The unfiltered side is enclosed with an impermeable barrier affixed to the peripheral wall and the filtered side is enclosed with a permeable water diffuser through which filtered fuel passes. A water separator assembly is disposed externally to the filter element receiving filtered fuel from the water diffuser. The water separator assembly includes water separator media preventing water from passing into the separator. The separator assembly interconnects to the filtered fuel outlet providing filtered, dewatered diesel fuel to the diesel engine.

摘要： 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,

摘要： A fuel filter comprises a filter housing, a filter assembly positioned within said filter housing, a fuel inlet adapted to receive fuel into the filter housing, and a fuel outlet. The filter assembly may have a first end cap, a second end cap, and a filter element positioned therebetween. The filter element may comprise a particulate filter component and a water sensing component, the water sensing component having a center tube, a water sensing layer, and a screen. The water sensing layer may wrap around at least a portion of the center tube and be secured in place by the screen. The water sensing layer comprises a gelling and thickening agent, such as methyl hydroxyethyl cellulose. In operation, the fuel filter is configured to direct fuel received at the fuel inlet to the fuel outlet by way of the water sensing component and the particulate filter component.
