A high-position anti-inclining fuel tank comprises fixed supporting legs, ventilation holes, an oil return opening, an oil filler, an oil inlet and an oil tank body. The high-position anti-inclining fuel tank is structurally characterized in that the fixed supporting legs are symmetrically and respectively connected to the front side face and the rear side face of the oil tank body, the oil filler is formed in one side of the top of the oil tank body, the ventilation holes are further formed in the top, close to the oil filler, of the oil tank body, the oil return opening is formed in the top of the oil tank body on the front side of the oil filler, and the oil inlet is further formed in the lowermost position of the lower bottom face of the oil tank body. The inclined included angle between the oil filler and the upper surface of the oil tank body is an acute angle. The lower bottom face of the oil tank body is in a step shape. The designed high-position anti-inclining fuel tank achieves the fact that when power station equipment works overhead and is irregularly inclined along with a bearing tool according to the wind direction, fuel oil in the fuel tank can be effectively supplied to a power station always until the fuel oil in the fuel tank is used up, and meanwhile the additional valve of products can be improved.
