A fuel hose which is less permeable to automotive fuels and excellent in low temperature property, hydrolysis resistance, weather resistance and ozone resistance. The fuel hose comprises an inner layer which contacts a fuel being transported, a fuel-permeation-resistant layer provided on an outer peripheral surface of the inner layer and an outer layer provided on an outer peripheral surface of the fuel-permeation-resistant layer, the inner layer being formed by the following (A), the fuel-permeation-resistant layer being formed by the following (B), and the outer layer being formed by the following (C): n(A) an alloy of elastomer components or a polyester resin softened by copolymerization; n(B) at least one polyester resin of polybutylene naphthalate (PBN) and polybutylene terephthalate (PBT); n(C) a polymer having flexural modulus of 350 to 650MPa obtained by blending at least one selected from the group consisting of polymer particles each having a core-shell structure, ethylene acrylic elastomer (AEM) and a styrene-isobutylene block copolymer into polybutylene terephthalate (PBT). |
