This specification describes the requirements for a multilayered vapor fuel carrying line. The construction consists of a heat, hydrocarbon, water, and chloride resistant outer cover of polyamide 12 (PA12) or polyamide 6/12 (PA612), a middle barrier layer of ethylene vinyl alcohol (EVOH), and an inner tube of polyamide 12 (PA12). The adhesion of the middle EVOH layer to the inner and outer layers is achieved by use of an appropriate tie layer.
