ABSTRACT:
A fuel hose for an automotive vehicle has an end section to which a connection-partner member is to be fitted. The fuel hose comprises an innermost layer formed of rubber or synthetic resin. The innermost layer has an inner surface defining an opening through which fuel flows and has an end section corresponding to the end section of the fuel hose. An outer layer is formed outside the innermost layer and formed of a material lower in fuel permeability coefficient than the innermost layer. Additionally, an end covering material is formed covering a surface region of the innermost layer which surface region includes the inner surface at a part extending from a sealing position to an end face of the innermost layer and the end face of the innermost layer. The end covering material is lower in fuel permeability coefficient than the innermost layer.
