<P>PROBLEM TO BE SOLVED: To provide a fuel tube having a polyamide resin layer superior in fuel impermeability, superior in melting moldability with a wide moldable temperature width, and superior in low water absorptivity, chemical resistance and hydrolysis resistance. Ž<P>SOLUTION: This fuel tube is characterized by including a polyamide resin layer in which a dicarboxylic acid component is composed of oxalic acid, and a diamine component is composed of 1,9-nonane diamine and 2-methyl-1,8-octane diamine, and the mole ratio of 1,9-nonane diamine and 2-methyl-1,8-octane diamine is 1:99 to 99:1.
