The disclosure relates to a fuel tank including a tank wall which has at least two wall sections opposite one another and a stiffening device situated between the two opposite wall sections. The disclosure further relates to a method for manufacturing such a fuel tank. According to the invention, it is provided that the stiffening device includes at least one connecting strut, each end of which has a profile section, which engages with one complementary profile section each on the two opposite wall sections of the container wall in a tension-resistant manner in such a way that the connecting strut absorbs compressive forces acting on the container wall. The method according to the disclosure for manufacturing a fuel tank including a stiffening device of the aforementioned type is characterized by the following steps: shaping the tank from a thermoplastic material in a blow mold, at least two coupling sections being created on opposite wall sections and an opening being created in one of the wall sections; removing the container from the blow mold; manual or mechanical insertion of at least one connecting strut via the opening into an interior of the container, the ends of at least one connecting strut each including a profile section, which may be coupled to one of the coupling sections of the wall sections in a tension-resistant manner; and manual or mechanical coupling of the profile sections of the connecting strut to the coupling sections of the wall sections.
