Fuel containment fuel tank

A fuel containment fuel tank (10) for a vehicle includes a tank shell (12) having a wall (18,20,22,24,26,28) 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), a fuel permeation barrier layer (34) disposed between the inner layer (30) and the outer layer (40), and a fuel containment layer (42) disposed adjacent the inner layer (30) to break-away from the inner layer (30) and contain fuel during an impact.
