Beschreibung
Zusammenfassung:	A fuel filter having a filter element for filtering out particles and water from a fuel flowing through the fuel filter and having a water drainage unit for conveying filtered-out water out of the fuel filter, in which the water drainage unit is embodied as a stand-alone unit that may be separated from the filter element as needed. Also a semipermeable membrane that is permeable to water rests flat on a support. Alternatively or in addition, the water drainage unit is provided with a porous element for the evaporation of the separated water. In another embodiment two water-permeable semipermeable and hydrophilic membranes are provided. Finally, the filter element is embodied essentially in the form of a hollow cylinder in which at least part of the water drainage unit may be situated on the interior of the hollow cylinder.
