ABSTRACT:
A fuel transporting hose used in a fuel pipe system is disclosed. The hose includes: an inner layer made of a fluorine-contained resin; an intermediate layer made of a synthetic resin other than the fluorine-contained resin and formed on the inner layer; and an outer layer made of a rubber material and formed on the intermediate layer. The inner layer may have electrical conductivity. Also disclosed is a resin tube in a fuel pipe system, which has at least an inner layer made of a fluorine-contained resin, and an outer layer made of a polyamide or polyester resin. In producing the resin tube, an outer surface of the inner layer which contacts the outer layer is subjected to a surface treatment for improving the adhesive strength between the inner and outer layers, and the inner and outer layers formed in lamination are subjected to a heat treatment at a temperature in a range of 150.degree. C. to a melting point of the outer layer.
