The invention relates to an automobile plastic fuel tank which is formed by connecting an upper tank body with a lower tank body. The automobile plastic fuel tank is characterized in that upper discontinuous compartment structures are arranged in the middle of the upper tank body in the length direction, and lower discontinuous compartment structures are arranged in the middle of the lower tank body in the length direction; the upper compartment structures are correspondingly in adhesive connection with the lower compartment structures in a staggered mode in order to improve the strength and stiffness of the fuel tank; lower gaps are formed between the lower ends of the upper compartment structures and the tank wall of the lower tank body, and upper gaps are formed between the upper ends of the lower compartment structures and the tank wall of the upper tank body. The automobile plastic fuel tank is good in pressure resistance, strong in deformation resistance, capable of being normally used on the condition that higher pressure is borne, and capable of restraining the generation of gasoline vapor.
