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.

A blow molded thermoplastic fuel tank with built-in fuel system components inside of the tank on separate and spaced apart internal brackets reduces the detrimental effects of thermoplastic swell to ensure fuel volume capacity is maximized, and appropriate clearances with the fuel tank wall are maintained. An internal configuration with separate spaced apart brackets provides more design freedom in the shape and configuration of the tank while enabling the tank shape to be thinner overall and fit within tighter spaces. The separate brackets also act as baffles to prevent sloshing noises of liquid fuel in the tank.

A fuel tank for a motor vehicle, a method for producing the fuel tank, and a single-track motor vehicle including the fuel tank, where the fuel tank includes at least two parts that are joined together where the parts delimit a receiving chamber for receiving a fuel. At least one of the two parts is produced by a co-injection moulding process.

The present 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, and a method for manufacturing such a fuel tank. According to the present disclosure, 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.
