The invention provides a range-extending vehicle fuel system and a control method, and belongs to the technical field of electronic control of range-extending vehicle fuel systems. According to the range extending vehicle fuel system and the control method, after the air pressure sensing device detects that the air pressure in the fuel tank is lower than the limit value, the fuel tank cover can be manually unscrewed, and the problems that in the prior art, a fuel system is complex in control logic and high in production cost are solved. The range extending vehicle fuel system comprises a fuel tank and a fuel steam absorbing device which are communicated through an isolating valve, the isolating valve is controlled by an electronic controller on a vehicle to be opened and closed, a fuel tank opening for refueling is formed in the fuel tank, a fuel tank cover is arranged at the fuel tank opening, the fuel tank cover is provided with an air pressure sensing device, and the air pressure sensing device is connected with the isolating valve. And after the air pressure sensing device detects that the air pressure in the oil tank is lower than a limit value, the oil tank cover can be manually opened.
