Abstract
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).
