The invention pertains to a filter designed for the simultaneous filtration and preheating of the fuel for an internal combustion engine. The filter barrel houses an annular filtering element through which the fuel generally circulates in a radial direction. Heating elements are provided in an axial tube of the barrel housing and inside an external annular chamber of that same barrel. Electrical resistors, for example, may be used as heating elements. The invention is designed to eliminate the paraffin flakes which appear in the fuel oil at low temperatures.
