The invention relates to the field of sealing structures, in particular to a novel pump opening sealing structure of a fuel tank, which comprises an oil pump flange mounted at a fuel pump opening of the fuel tank, and an L-shaped sealing ring is arranged between the fuel pump opening of the fuel tank and the oil pump flange. The L-shaped sealing ring comprises a vertical sealing part attached to the inner wall of the fuel tank and a horizontal sealing part attached to the outer top wall of the fuel tank, and a locking ring used for pressing the fuel pump flange to the fuel pump opening of the fuel tank is arranged on the circumferential face of the fuel pump opening of the fuel tank. The sealing structure at the fuel pump opening has the advantages of simplicity in processing and assembling and better sealing effect.
