Abstract
A fuel filter insert for a fuel filter is provided with a prefilter element and a main filter element which are arranged one atop the other in an axial direction relative to a longitudinal axis of the fuel filter insert. The main filter element has a water separating unit configured to separate water contained in a fuel to be filtered. The water separating unit has a water discharge channel for water separated from the fuel, wherein the water discharge channel is extending in the axial direction at least partially through the prefilter element. A fuel filter with such a fuel filter insert has a filter housing accommodating the fuel filter insert and the water discharge channel of the fuel filter insert is fluidically connected with a water collecting chamber of the filter housing.
