The invention relates to a method for producing a multi-chamber tank (1) for fuels of motor vehicles, said tank comprising at least one internally coated first (2) and at least one internally coated second chamber (3). The method comprises the following steps: making a first metal tank segment (4) available, said segment containing the first chamber (2) and an externally protruding peripheral collar (8), rotolining the first tank segment (4) to internally coat the first chamber (2) with a plastic material (13), and connecting a second metal tank segment (5) to the peripheral collar (8) to form the second chamber (3) between the second tank segment (5), the peripheral collar (8) and the exterior (7) of the second tank segment (4), the first tank segment (4) being retained by its peripheral collar (8) during rotolining.
