Abstract

A filter element for a fuel filter has first and second end plates and a particle filter medium arranged between the first and second end plates. A bayonet protrusion on the first end plate is designed to engage a bayonet receptacle of the filter housing by rotation of the filter element about a filter element longitudinal axis. An internal sealing element on the second end plate is designed to separate a raw side from a water collecting chamber of the fuel filter. The filter housing has a filter housing body and a cover screwed onto the filter housing body. The filter housing has a bayonet receptacle arranged on its inner side. By rotating the filter element about a filter element longitudinal axis of the filter element, the bayonet protrusion engages the bayonet receptacle of the filter housing when the cover is unscrewed from the filter housing body.
