Fuel hose
 A fuel hose comprises a single layered or multi-layered tubular rubber body and a thin film resin layer formed on the inner circumferential surface of the innermost layer of the tubular rubber body. The resin layer is formed of a resin such that an amount of permeation of 10% ethanol-mixed gasoline is 2 mg/cm.sup.2 /day (at 60.degree. C.) or less when the thickness of the resin layer is 0.1 mm. A preferred example of such a resin is EVOH with an ethylene content of from 35 to 50 mol % or polybutylene aromatic ester. The fuel hose has necessary flexibility and shows excellent impermeability even to an alcohol-mixed gasoline.
