ABSTRACT:
An automotive fuel hose comprising a two-ply rubber tube covered with a reinforcing fiber layer and further with a protective rubber layer. The two-ply rubber tube is constituted of a very thin inner layer of a fluorine rubber resistant to fuel, even to sour gasoline, and an outer layer of a synthetic rubber, such as epichlorohydrin rubber or ethylene-acrylic rubber, which is less resistant to sour gasoline but is superior in cold resistance. Both the inner and outer layers are formed by extrusion, preferably simultaneously.
