The invention discloses a vehicle-body loading type vehicle whole fuel tank structure. The whole fuel tank comprises horizontal beams, vertical beams and a fuel tank, wherein the horizontal beams are connected between the two vertical beams, outer side plates vertically downwards extending are arranged on the outer sides of the vertical beams, the fuel tank is arranged between the two vertical beams, and the two sides of the fuel tank are welded and fixed with the outer side plates. A sewage tank is mounted in the fuel tank, a cover plate of the fuel tank covers a cover plate of the sewage tank, the size of the opening of a fuel hole is larger than that of a fuel leakage hole, and the cover plates of the fuel tank and the sewage tank are welded and fixed along the edge of the fuel hole. The outer side plates of the vertical beams are used as the main vertical plate of the fuel tank, and welded with the outer wall of the fuel tank, and thus the rigidity of the whole fuel tank is increased. The welded fuel tank is welded with the vertical beams, the horizontal beams and a reinforced horizontal beam to form a whole body, and thus the whole fuel tank is formed, the bearing capability of the fuel tank is increased, the rigidity of the middle structure is increased, and under the requirement of the same load, the weight of the vehicle body is obviously reduced and the requirement of light-weight design of the vehicle body is satisfied.
