<p>A motor vehicle fuel tank is disclosed, having a fluid pressure thermoformed tank wall comprising a bottom wall and opposed side walls unitary with and extending upwardly from the bottom wall. The fuel tank is characterized in that it has a fuel reservoir unitary with the tank wall and, specifically, formed by convolutions in the bottom wall of the tank. The fuel reservoir comprises two opposed substantially C-shaped ridges extending upwardly into the tank from the plane of the bottom wall, each such ridge extending from a corresponding one of the side walls toward the opposed side wall to a second end, diminishing in height to approximately the plane of the bottom wall at such second end. The two C-shaped ridges cooperate to partially surround a portion of the surface area of the bottom wall of the fuel tank. A channel between each ridge and the end of the other ridge permits fuel to flow into the fuel reservoir even during low fuel conditions.</p> |
