PROBLEM TO BE SOLVED: To solve a problem of improper outflow and scattering at the time of fuel filling, which is a defect of a publicly known system, and to improve recovery of steam. SOLUTION: A plastic fuel safety system comprises a liquid fuel tank which is provided with a filler pipe (10) with a guide section for an oil supply nozzle comprising a sealing device, a float valve (6), which is normally open, for the degassing and venting of the tank, and a breather pipe (19) for transpirating the vapours and for fixing the maximum level of the liquid in the tank. The pipe (19) connects the top part of the tank with an area located downstream of the sealing device (2). A tank for a vehicle is provided with one such safety system. When in a closed position, a filler pipe cap isolates the tank degassing and venting circuits. COPYRIGHT: (C)2008,JPO&INPIT
