<p>A fuel permeation barrier fuel tank (10) for a vehicle includes a tank shell (12) having a wall formed from a plurality of layers (30,32,34,36,38,40). The layers (30,32,34,36,38,40) include at least an inner layer (30), an outer layer (40) and a fuel permeation barrier layer (34) disposed between the inner layer (30) and the outer layer (40), and a thermoformable layer (36) disposed between the fuel permeation barrier layer (34) and the outer layer (40) to improve permeation resistance of the fuel tank (10). <IMAGE></p> |
