PROBLEM TO BE SOLVED: To provide a hose for an automobile fuel system which is excellent in low fuel permeability, impact resistance, hydrolytic resistance and interlaminar adhesiveness. SOLUTION: The hose for the automobile fuel system is provided with an annular inner layer 1 for communicating a fuel and a low fuel permeable layer 2 on its outer periphery, and the inner layer 1 and the low fuel permeable layer 2 are laminated under a condition where their interfaces are brought into contact with each other. The inner layer 1 comprises a fluororesin with a functional group and the low fuel permeable layer 2 comprises a polyester resin with a naphthalene ring. COPYRIGHT: (C)2004,JPO |
