摘要: There is provided a hose for fuel piping which has an inner layer portion having a single layer of a thermoplastic resin having a low fuel permeability, the inner layer portion has a thickness of at least 0.3 mm at a maximum thickness portion, and an outer layer portion of a thermoplastic elastomer. The inner layer portion is laminated to the outer layer portion by a bond strength of 0.6 kgf/cm or less. In a modification, the inner layer portion of a thermoplastic resin having a low fuel permeability can be coated with a thermoplastic resin.
