A fuel filter has a housing with fuel inlet for fuel to be purified, fuel outlet for purified fuel, and water outlet for water separated from the fuel. A filter element is arranged in the housing and separates seal-tightly fuel inlet from fuel outlet. The filter element has a filter medium formed as a hollow body and flowed through from the interior to the exterior of the filter element or in reverse. A coalescing medium formed as a hollow body is arranged in a flow path of the fuel downstream of the filter medium for separating water from the fuel. The coalescing medium surrounds the filter medium or is arranged in the interior. The coalescing medium has at least one nonwoven layer that coalesces water and has a main orientation of fibers transverse to a main flow path of separated water downstream of the coalescing medium.
