Abstract: A filter cartridge that includes a canister configured to hold a filter element. The canister has a canister body with an open end and an end closure. The end closure has a central annular element locating feature, and an annular frame portion circumscribing the central annular element locating feature. The canister body and end closure have cooperating geometry for retaining the end closure to the open end of the canister. The cooperating geometry includes an axial retention mechanism for maintaining an attachment between the canister and the end closure. The axial retention mechanism is configured to maintain the attachment solely via mechanical interference.

Abstract: Filter elements and filter systems are provided. The filter element allows for a reversed flow of fluid through the filter element when flowing from a first port to a second port of a filter head of the filter system. The filter element includes a standpipe in a central cavity of a tube of filter media that is fluidly connected with an exterior of the tube of filter media by a radial flow conduit and an axial flow tube.

Abstract: A filter cartridge has a keyed end cap which is configured and shaped for unlocking an associated valve mechanism that comprises a latch device and a valve. In this manner, when the fuel filter cartridge is placed into a fuel filter housing having such a latch and valve mechanism, the fuel filter cartridge is operable therein to filter fluid and pass the fluid into a standpipe contained within the fuel filter housing. The fuel filter cartridge of this type generally includes pleated filter paper which is disposed between two opposed end caps. The keys may be provided along the bottom end cap.
