Estimating the term…
A fuel filter has a filter housing and a fuel filter insert exchangeably arranged in the filter housing and provided with a prefilter element and a main filter element. Prefilter element and main filter element are positioned one behind the other in the filter housing in axial direction of the filter housing. A fuel discharge channel is arranged in the filter housing below the fuel filter insert. In operating position of the fuel filter insert in the filter housing, the raw sides of prefilter element and of main filter element are sealed relative to the fuel discharge channel by seal-tight contact of the fuel filter insert on the filter housing. The raw side of the main filter element, when the fuel filter insert is moved by axial movement away from the operating position, is fluidically connected with the fuel discharge channel via the raw side of the prefilter element.
A fuel filter comprising:
A fuel filter insert for a fuel filter that comprises a filter housing and a fuel discharge channel arranged in the filter housing, the fuel filter insert comprising a prefilter element and a main filter element which are arranged, positioned one behind the other, in an axial direction of a longitudinal axis of the fuel filter insert, wherein the fuel filter insert is configured to be inserted into the filter housing in an operating position such that a raw side of the prefilter element and a raw side of the main filter element are sealed relative to the fuel discharge channel by seal-tight contact of the fuel filter insert on the filter housing, wherein the fuel filter insert is configured such that the raw side of the main filter element, when the fuel filter insert is moved by an axially oriented movement away from the operating position in the filter housing, is fluidically connected with the fuel discharge channel via the raw side of the prefilter element.
