A fuel tank ventilation assembly comprises a ventilation member main body. The ventilation member main body comprises a ventilation member cover and a ventilation assembly, the ventilation assembly is mounted at the bottom of the ventilation member main body, and the bottom of the ventilation member main body superposes the ventilation assembly. U-shaped ventilation grooves are distributed at two sides of the medial axis of the ventilation assembly, and a vent (3) and a vent (2) are respectively disposed at the upper end of the lower end of each U-shaped ventilation grooves. The center of the bottom of the ventilation assembly is provided with a vent (4), the vent (4) is provided with a piston, one end of the piston is connected with a spring, one end of the spring is fixed to a spring base, one side of the spring seat is provided with a gas dashpot, the gas dashpot communicates with a ventilation groove, and the bottom of the ventilation groove is provided with a vent (1). The ventilating sensitivity and the reliability of a fuel tank can be raised by disposing the U-shaped ventilation grooves, a technical issue that a plastic fuel tank will be shriveled under high negative pressure can be solved, the fuel tank can be effectively protected, and the service life of the fuel tank can be prolonged.
