The hot melt seam sealer (35) also includes a meltable adhesive layer (38) capable of binding with the barrier polymer and a surface of the fuel tank (10). Also, a 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). The layers (30,32,34) include at least an inner layer (30), an outer layer (34), a fuel permeation barrier layer (32) disposed between the inner layer (30) and the outer layer (34), and the hot melt seam sealer (35) is disposed over the outer layer (34) at a seam area of the fuel tank (10).",
