Abstract

The invention relates to a fuel filter for an internal combustion engine, comprising a filter housing consisting especially of metal, and a filter element and a pressure-regulating valve located in said filter housing. The aim of the invention is to ensure that no noise originating from the pressure-regulating valve is emitted. To this end, the pressure-regulating valve is mounted in the filter housing in such a way that vibrations are dampened.
