ABSTRACT:
In the case of a fine filter for a fuel feed unit of a motor vehicle, a filter element has at least two sections which surround the fuel feed unit concentrically. In the fitted state of the fine filter, the sections are fastened to the fuel feed unit and to a surge chamber. The filter element has proven particularly cost-effective and enables the use of a particularly small mesh width while requiring little space.
