Abstract
A polymeric fuel tank having a first body joined to a second body is constructed having a substantially continuously barrier layer surrounding the tank. The first body has an inner surface terminating at a free edge and a first mating surface adjacent the free edge. A first barrier layer is fixed adjacent the inner surface of the first body. The second body has an inner surface terminating at a free edge and has a second mating surface adjacent to the first mating surface and the free edge of the second body to define a fuel cavity. A second barrier layer is fixed adjacent the inner surface of the second body. At least one weld joint joins the first mating surface to the second mating surface and the first barrier layer to the second barrier layer to provide the continuous barrier layer in the fuel tank.
