PROBLEM TO BE SOLVED: To provide a fuel supply device enabling to use vegetable oil as fuel without converting diesel engine by solving a problem in a conventional technology how viscosity of vegetable oil is reduced. SOLUTION: In this fuel supply device, the engine 6 is started with using light oil as fuel and cooling water 7 of which temperature is elevated due to a secondary effect of temperature rise of the engine is used. Elevated temperature cooling water 7 is always circulated outside of a plurality of pipes 9 between an upper stream side of a filter 14 and a fuel tank 11 provided with a rear part heating device. 100% vegetable oil flows in an inside pipe. Viscosity of vegetable oil in the pipe and the fuel tank can be easily reduced without an electric heater and mixing up fuels. COPYRIGHT: (C)2004,JPO
