Abstract

A fuel hose is provided, which includes an inner tube including a rubber layer and a rubber layer, a resin layer provided around an outer periphery of the inner tube and comprising a thermoplastic resin as a major component, and an outer tube provided around an outer periphery of the resin layer and including a reinforcement thread layer and a rubber layer. The inner tube of the fuel hose has a dynamic loss (Tan δ) of 0.3 to 1.2. The fuel hose has an outer diameter change ratio of not greater than 10% and a volume change ratio of not less than 15% when the internal pressure of the hose is increased by 1 MPa. The fuel hose is less costly, and has a fuel permeation resistance (fuel barrier property) as well as a pulsation suppressing property.
