The invention relates to a passenger car fuel tank lifting assembly device, which comprises a fuel tank, a fuel tank bracket for installing the fuel tank, a lifting hanger, a pulley, a pulling rope and a fuel tank lifting mechanism for lifting the fuel tank up and down. The fuel tank bracket is detachably connected to the body frame. The bottom of the lift hanger is connected to the fuel tank bracket. The pulley is installed on the body frame above the fuel tank bracket and the lifting hanger. The fuel tank lifting mechanism includes a rotating shaft, a rotating shaft mounting seat and a rotating handle for rotating the rotating shaft; the rotating shaft is in rotation with the rotating shaft mounting seat; and the rotating handle is detachably mounted on the end of the rotating shaft. One end of the pulling rope is connected with the top of the lifting hanger, and the other end is connected with the middle part of the rotating shaft after walking around the pulley. The assembly device can eliminate the deficiencies of the existing fuel tank installation structure, and has the characteristics of simple and efficient assembly operation, low production cost, elegant appearance, low labor intensity and the like.
