Fuel hose and method of producing thereof
 A fuel hose comprising an outer rubber layer wherein polysulfide is crosslinked so that polysulfide bonding density is not less than 4.times.10.sup.-5 mol/cm.sup.3 and an epoxy compound having epoxy equivalent at not more than 300 is contained, and an inner polyamide resin layer which is laminated on the inside face of the outer rubber layer and bonded thereon by heat treatment. Since the polyamide resin powder is melted by the heat treatment and the polysulfide bonding decomposes so that the resultant residue after decomposition combines with polyamide molecules, resulting in a direct and strong bonding of the outer rubber layer and the inner polyamide resin layer. Moreover, since the special epoxy compound is mixed therein, it is possible to set up the heat treatment condition at a rather mild one.
