PROBLEM TO BE SOLVED: To provide a fuel hose for automobiles excellent in low fuel permeability, impact resistance, hydrolysis resistance and interlaminar adhesion. SOLUTION: The fuel hose for automobiles has an annular inner layer 1 permitting fuel to flow, the low fuel permeability layer 3 formed on the outer periphery of the inner layer and an adhesive layer 2 for bonding the inner layer 1 and the low fuel permeability layer 3. The inner layer 1 is constituted of a fluororesin and the adhesive layer 2 is constituted of a resin having an epoxy group and the low fuel permeability layer 3 is constituted of a polyester resin having a naphthalene ring.
