Fuel filter insert having a pre- and a main filter element, and a fuel filter

A fuel filter comprising

• a filter housing;
• and
• a fuel filter insert arranged in an interior of the filter housing, the fuel filter insert including:
• a pre-filter element having an upper and a lower end plate, the end plates arranged on opposing ends of filter medium of the pre-filter element;
• and
• a main filter element having an upper and a lower end plate, the end plates arranged on opposing ends of filter medium of the main filter element;
• wherein the pre-filter element and the main filter elements are arranged one above the other in a direction of a longitudinal axis of the fuel filter insert;
• wherein at least one of the filter elements is through-flowable from the outside to the inside by fuel in a radial direction relative to the longitudinal axis;
• and
• a flow channel for the fuel pre-filtered by the pre-filter element;
• wherein the flow channel is arranged to extend in the axial direction between the pre-filter element and the main filter element;
• and
• wherein the flow channel in the axial direction is directly limited by and the end plates of the pre-filter element and an end plate of the main filter element;
• wherein the fuel filter insert having the two end plates of the pre-filter element limiting the flow channel sealingly abuts against an inner side of the the filter housing;
• wherein a lateral fuel outlet is formed at the filter housing, via which the flow channel is fluidically connectable to a fuel pump to pump the fuel pre-filtered by the pre-filter element via a fuel inlet formed on the side of the filter housing, to the main filter element.
