ABSTRACT:
A fuel-line tube formed wholly of plastic has ends provided with fittings connecting it to the engine and tank and capable of resisting disconnection from the tube and tank when stressed at less than a predetermined pullout force. This tube has an outside diameter of less than 15 mm and is formed with a corrugated crash-resistant section of a predetermined length which is a maximum of 50% of a precorrugated length and capable of elongation in response to a crash with a tensile force smaller than the pullout force.
