The invention relates to a fuel tank for vehicle outer end lying along the spare wheel

Motor vehicles in which the spare wheel and the inclined plane moved downwards, which is formed by the t tank below the trunk floor in the back- 45 floor of the fuel tank; the danger 'are arranged on the other tank in the longitudinal und.der that the fuel tank is damaged, this tung t furthest toward the vehicle transverse center lies down.
