A fuel pipe having excellent gasoline barrier properties, stress crack resistance, dimensional stability, and impact resistance is provided. A fuel pipe comprising a multilayer structure having a layer made of a modified ethylene-vinyl alcohol copolymer (C) and a layer made of a resin (F) other than (C), wherein the modified ethylene- The vinyl alcohol copolymer (C) is obtained by modifying an unmodified ethylene-vinyl alcohol copolymer (A) with an epoxy compound (B) having a double bond. The modification amount by (B) is 0.1 to 10 mol% with respect to the monomer unit of the ethylene-vinyl alcohol copolymer (A), and at least a part of the modified ethylene-vinyl alcohol copolymer (C). Is crosslinked, the gel fraction thereof is 3% by mass or more, and the thickness of the layer made of the modified ethylene-vinyl alcohol copolymer (C) is 5 to 4000 μm. It is a postal piping.
