Fuel system for a vehicle with a heat enigine, comprising a hollow body made of plastic, designed to contain or to transport fuel, and means of covering this hollow body by means of a rigid jacket surrounding the hollow body. The covering means form, with the surface of the hollow body, a confined space fitted with a device for flushing by means of air. The air which entrains any emitted vapours is purified before being discharged into the atmosphere or is mixed with the air blown out by the engine. The invention is applicable to a double jacket for a fuel tank made of plastic or to a fuel pipe fitted with a concentric channel.
A Fuel system for a vehicle with a heat engine, comprising a hollow body made of metal or of plastic, designed to contain or to transport fuel, and means of covering this hollow body, in which at least part of the outer surface of the hollow body is surrounded by a rigid jacket, the hollow body and the rigid jacket defining, at least in part, at least one confined space around the hollow body, and according to which the confined space is fitted with a device for flushing by means of a gas intended to be subjected subsequently to a physical or chemical treatment, wherein the confined space is defined, at least in part, by the jacket and by a wall of the vehicle.
