Patent ID: 10773190

Abstract:
A fuel filter insert for a fuel filter has a low-pressure region with prefilter element arranged therein. A high-pressure region arranged fluidically downstream of the low-pressure region has a main filter element arranged therein. Prefilter element and main filter element are arranged one atop the other axially in the fuel filter insert. A wall element projects away from the main filter element in axial direction and extends at least partially through the prefilter element. Low-pressure region and high-pressure region at least over sections thereof are separated from each other by the wall element. A fuel filter is provided with a filter housing in which the fuel filter insert is arranged. The filter housing has a fuel outlet and a fuel inlet for fuel prefiltered by the prefilter element. Fuel inlet and fuel outlet are fluidically positioned between low-pressure region and high-pressure region and a fuel pump is connectable thereto.
