Abstract
A fuel filter for a fuel supply system of an internal combustion engine may include a filter housing, which may have an untreated-side inlet, a treated-side outlet, and an untreated-side return line. The fuel filter may also include a filter element arranged in the filter housing, and a closure element, which in an operationally ready state of the fuel filter may close off the return line. The fuel filter may include an untreated space and a treated space, and may separate in the filter housing the untreated space communicating with an inlet and the return line from the treated space communicating with the outlet. The fuel filter may further include a pressure sensor configured to measure a pressure build-up in the treated space, wherein the fuel filter may be configured to enable the pressure build-up to reach a predetermined threshold at which the engine may be started.
