These specifications define multilayered fuel and vapor lines comprised of a heat, hydrocarbon, water, and chloride resistant outer cover of polyamide or alloyed polyamide or equivalent material. The cover is well adhered to a low fuel permeability and fuel/alcohol blend resistant inner tube such as conductive or non-conductive fluorinated ethylene propylene (FEP) or equivalent material. This construction is sufficiently flexible for ease of forming, assembly, and routing, and is resistant to kinking.
