ABSTRACT:
A heatable fuel filter for a motor vehicle engine is provided wherein an electric heating element is positioned between a filter head and filter box. In order to prevent fuel contained in the filter head and fitler box from being discharged to the surroundings when the filter box is changed, the filter box is provided with an element for collecting and containing this fuel. A lid container provided for the filter box is filled by the heating element when the filter box is attached to the filter head and heating element. When the filter box is removed from the heating element and filter head, the volume previously occupied by the heating element becomes available for collecting and containing residual fuel flow from the filter head and heating element. The lid container preferably has a volume greater than the volume of fuel contained in the filter head and the heating element.
