PROBLEM TO BE SOLVED: To provide a fuel hose having superior calcium chloride resistance, achieving both of fuel low permeability and pulsation reduction performance, and having a superior interlayer adhesion property.SOLUTION: A fuel hose includes an inner layer 1 composed of a specific resin such as polyamide 9T, an intermediate layer 2 disposed while kept into contact with an outer peripheral face of the inner layer 1 and composed of a component (B), and an outer layer 3 disposed while kept into contact with an outer peripheral face of the intermediate layer 2 and composed of a component (C), and the layers are interlayer-bonded to each other. (B) is a polyamide ternary copolymer prepared by copolymerization of (b1), (b2) and (b3). (b1) is polyamide 6, (b2) is at least one of polyamide 66 and polyamide 610, and (b3) is polyamide 12. (C) is an aliphatic polyamide resin (excluding polyamide 6 and polyamide 66).SELECTED DRAWING: Figure 1 |
