The invention relates to the technical field of engineering machinery, and provides a fuel oil system and engineering machinery, the fuel oil system comprises a fuel oil tank, a platform and a crawling ladder, the fuel oil tank is provided with a fuel oil filling port and an exhaust hole, the exhaust hole is provided with a first one-way valve which is conducted from inside to outside, and a buoy is arranged in the fuel oil tank; the quick refueling assembly is used for being communicated with a fuel filling port and used for filling fuel into the fuel tank, when the liquid level in the fuel tank reaches the preset liquid level, the buoy blocks the first one-way valve, and the quick refueling assembly stops; the platform is arranged on the side of the fuel tank and used for bearing operators. The crawling ladder is rotationally connected with the platform, and the crawling ladder is used for switching between a first position and a second position; when the crawling ladder is located at the first position, th
