Abstract

A fuel filter has a housing having an intake and an outlet. A filter element is arranged in the housing such that a filtered area is separated seal-tightly from an unfiltered area. A flow passage is provided between the unfiltered area and the filtered area. A porous filter member closes off the flow passage, wherein the porous filter member is arranged seal-tightly on a wall arranged about the flow passage. The filter element has a filter medium and a geodetically upper and a geodetically lower terminal disks arranged at end faces of the filter medium. The filter medium is connected seal-tightly to the terminal disks. The flow passage is arranged in the geodetically upper terminal disk that forms the wall.
