Corrugated pipe of a fuel line

The pipe (1) has a pliable shaft comprising a shaft portion (3), a shaft crest and a shaft trough. The shaft portion includes a region (4), and the shaft comprises large diameter in the region. Ends of the region and another region (5) of plain ended pipe portions (6, 10) are formed with variable internal diameters. The regions are spaced with each other. Wall thickness of the regions is equal to wall thickness of the shaft portion. The pipe portions are arranged with a cylindrical section. A fuel line connects an outlet of a fuel pump with an engine of a motor vehicle.
