The invention discloses a fuel oil filling pipe assembly. The fuel oil filling pipe assembly comprises an oil filling pipe in the specific space curved moving direction and a gas outlet pipe in the specific space curved moving direction, wherein the gas outlet end of the gas outlet pipe is communicated with the oil filling end of the oil filling pipe. An anti-spill sleeve capable of preventing fuel oil from overflowing when an oil gun fills oil is arranged in the oil filling end of the oil filling pipe in an interference fit mode. The oil filling end of the oil filling pipe is provided with an oil filling cavity capable of containing the oil gun for filling oil, wherein the oil filling cavity is expanded and formed through the flaring process; an inner circle sealing bevel which becomes larger gradually and is in sealing fit with a fuel tank cap and an arc-shaped surface which turns over outwards in an arc shape and can be matched with the fuel tank cap in a limiting mode are formed on the inner wall of a port of the oil filling cavity in sequence. An internal thread which is in threaded connection with the fuel tank cap is integrally formed on the inner wall of the oil filling tank through the rolling process and located below the inner circle sealing bevel. The anti-spill sleeve is fixedly mounted in the oil filling cavity and located below the internal thread. The fuel oil filling pipe assembly is concise in structure, smooth in oil filling, good in sealing performance, high in safety coefficient and capable of meeting the requirement of a current automobile market for oil filling.
