Method of producing fuel hose and fuel hose obtained thereby
A method of producing a fuel hose having superior adhesive reliability with superior initial adhesive strength between a tubular fluororesin inner layer and a thermoplastic resin outer layer and with restrained deterioration in adhesive strength after heat aging and immersion into fuel under severe conditions such as an inside of an engine compartment. The method includes plasma treatment on a peripheral surface of the tubular fluororesin inner layer, at least one treatment of water treatment and silane coupling agent treatment on the plasma treated surface and formation of the thermoplastic resin outer layer on the treated peripheral surface.
