<p>A fuel tank for motor vehicles, provided internally with a fuel feed pipe for connection to a fuel supply system of a motor vehicle engine, includes an inner wall extending between the lower wall and the upper wall of the tank, and surrounding the fuel feed pipe to define a chamber having a smaller capacity than the capacity of the tank and containing the fuel feed pipe. This chamber communicates with the remaining part of the tank through apertures in the inner wall. The tank is constituted by lower and upper plastics half shells which are welded together and have opposing main walls which define the lower wall and the upper wall of the tank respectively. The lower and upper half shells are provided with ribs which project into the tank, the ribs projecting from the opposing main walls being in contact with one another so as to define the inner wall. This inner wall prevents the fuel from all collecting in a peripheral zone of the tank due to longitudinal or transverse accelerations and decelerations of the vehicle during movement, even when the tank is not completely full, thereby ensuring a constant supply of fuel to the engine through the fuel feed pipe.</p> |
