Abstract

The invention concerns a fuel filter 10, in particular for diesel fuels, that comprises a housing 11 and a filter medium 12. The filter medium 12 is arranged by means of a filter medium holder 24 in the housing, wherein the filter medium holder comprises a venting bore 25. Through the venting bore 25 gases that collect in the upper area of the fuel filter can pass from the crude chamber 21 into the clean chamber 22. For avoiding that contaminants can escape through a clean outlet 18 from the fuel filter 10 and damage components downstream, a clean medium 26 is provided that retains such contaminants.
