PURPOSE: Provided is a fuel tube composed of plastic inner, central and outer layers, which is incorruptible and can be produced simply with low cost. CONSTITUTION: The tube comprises an inner layer(10) composed of 90-95% of conductive PA6(polyamide) and 5-10% of carbon black, an outer layer(11) composed of 35-55% of PA6 and 45-65% of PP, and a central layer(12) made of PA6 for bonding the outer layer and the inner layer. The outer, the inner and the central layers are formed in one body by extruding the layers.
