The fuel filter () contains a filter element () and an additive tank () in a housing (). The filter element is engaged against the removable cover () of the housing and has a filter medium () extending in an annular manner around an inner space (). An additive release device () extends into this inner space () to distribute liquid additive from the tank () into a fuel circulation circuit for an internal combustion engine. The additive selectively flows into a sealed distribution channel (DC) of the device () depending on an open or closed configuration of an actuator component () associated with the distribution channel. The distribution channel (DC) opens into a fuel channel () of the cover () that has a larger cross-section than the distribution channel (DC).

In a filter cartridge (CC) for a fuel filter, the filter element () and the additive module are connected and typically stacked so as to allow them to be integrally inserted into a filter housing. The substantially annular filter medium () delimits an inner space () into which at least one part () of the attachment end of the additive module can be engaged. The liquid additive is stored in a casing forming a tank () that is placed at a fuel pressure and delimits an internal volume (V) that can be varied so as to maintain an identical pressure between the liquid additive and the fuel at the periphery (V) of the tank (). The additive module has an external connection () with a liquid additive outlet pipe (), said external connection () including sealing means () for automatically closing the outlet pipe in a fluidtight manner when the external connection is in a disengaged state.

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.
