Abstract
The invention concerns a fuel filter, in particular for diesel fuels, that comprises a housingand a filter medium. The filter mediumis arranged by means of a filter medium holderin the housing, wherein the filter medium holder comprises a venting bore. Through the venting boregases that collect in the upper area of the fuel filter can pass from the crude chamberinto the clean chamber. For avoiding that contaminants can escape through a clean outletfrom the fuel filterand damage components downstream, a clean mediumis provided that retains such contaminants.
