The invention belongs to the technical field of automobiles, and discloses a fuel supply system and a vehicle. The fuel oil supply system comprises a main oil supply mechanism, an auxiliary oil supply mechanism, a diesel filter and a degassing switching mechanism. The main oil supply mechanism comprises a large oil tank and a small oil tank which are communicated with each other, the small oil tank is provided with an oil supply port and an oil return port which are respectively communicated with the engine, and a heating assembly is arranged in the small oil tank; the auxiliary oil supply mechanism comprises an auxiliary oil tank communicated with the oil conveying pipe; an inlet of the diesel filter is communicated with the small oil tank, and an outlet of the diesel filter is communicated with the engine; the degassing switching mechanism is connected among the large oil tank, the diesel filter, the small oil tank and the oil conveying pipe and has a first state, and the large oil tank is communicated with the diesel filter; in the second state, the diesel filter communicates with the oil-conveying pipe; in the third state, the oil conveying pipe communicates with the small oil tank, and the diesel filter communicates with the degassing switching mechanism. The fuel oil supply system meets the long-mileage running requirement of the vehicle, and meanwhile the problem that the vehicle is difficult to start in a low-temperature environment is solved.
