The invention discloses a fuel supply system for a special vehicle. The fuel supply system comprises a left fuel tank, a right front fuel tank, a right rear fuel tank, a small fuel tank and a reversing valve. The left oil tank is not higher than the right front oil tank and the right rear oil tank, the left oil tank, the right front oil tank and the right rear oil tank are all higher than the small oil tank, and the bottoms of the right front oil tank and the right rear oil tank are communicated through oil pipes; the bottoms of the left and right front oil tanks are respectively connected with the bottom of the small oil tank through pipelines; diesel pumps are mounted at the bottoms of the small oil tanks; an outlet of the diesel pump is connected with an engine oil inlet through an oil pipe; an oil supply switch is arranged on the oil pipe; an engine oil return opening is connected with an oil inlet of a reversing valve through an oil pipe, and two oil outlets of the reversing valve are connected with the tops of the left oil tank and the right front oil tank respectively. The oil supply device is simple in structure, continuous oil supply by inclining forwards and backwards by 32 degrees and inclining leftwards and rightwards by 20 degrees is achieved, and fuel oil can be effectively prevented from overflowing.
