Abstract

A filter device includes a filter housing and a filter element disposed in the filter housing. The filter element is configured to be penetrated by a fuel flow in a radial direction from a raw end to a pure end of the filter element. A water separator is disposed at the pure end of the filter element and extends in an axial direction of the filter element. The water separator has a hydrophobic and annular diaphragm through which fuel can flow from a radially outward to a radially inward direction.
