The invention belongs to the technical field of automobile parts and provides a fuel tank ventilation structure. The fuel tank ventilation structure comprises a ventilation pipe with one end which is communicated with a fuel tank, wherein the ventilation pipe is located at a top of the fuel tank; the fuel tank ventilation structure further comprises a mounting bracket for mounting the fuel tank, wherein a filter chamber is arranged on the mounting bracket, the filter chamber is arranged outside the fuel tank, an air inlet end, far away from the fuel tank, of the ventilation pipe stretches into the filter chamber, and the filter chamber is communicated with the fuel tank through the ventilation pipe. The purpose of the invention is to provide a fuel ventilation structure. By additionally arranging the filter chamber, air outside the fuel tank enters the fuel tank after being filtered by the filter chamber, pollutants such as dust are reduced, the cleanness of air entering the fuel tank is guaranteed, the fuel is prevented from being polluted, the combustion efficiency of the fuel is improved and the normal working of the vehicle is guaranteed.
