PROBLEM TO BE SOLVED: To provide a fuel feed device wherein in order that a mixture of a fuel and an emulsifying agent is stored beforehand in a fuel tank of a Diesel engine car or the like which uses emulsion fuel, the fuel feed device is mounted to an oil feed nozzle, and the fuel is fed, while the emulsifying agent is mixed into the fuel through an emulsifying agent feed nozzle, which is mounted to the oil feed nozzle, when oil is fed, so as to coact with the oil feed nozzle. SOLUTION: The fuel feed device has a fuel storage tank 6 and an emulsifying agent storage tank 18. An emulsifying agent feed nozzle 13 is mounted integrally to an oil feed nozzle 11, and the nozzle 11 is operatively connected to a pump 4 for feeding fuel to the nozzle 11 and a motor 3 to operate a motor 15 on the side of the emulsifying agent. If a trigger 24 is pulled to feed oil, the flow of fuel in a delivery pipe 7 is sensed, and rotation of the motor 15 is increased by a controller 10 so that a check valve 33 is opened by the delivery pressure of the fuel and hence the emulsifying agent is added to the fuel. The fuel and the agent are mixed at a mixer. If the flow of fuel in the pipe 7 stops, the motor 15 is stopped.
