PURPOSE: A fuel preheating system of a diesel vehicle using a fuel combustion heater system is provided to improve the flowing effect of fuel and to remove the paraffin generated in the diesel fuel in low temperature by heating the diesel fuel of the fuel filter by using a fuel combustion heater. CONSTITUTION: A fuel preheating system of a diesel vehicle using a fuel combustion heater system is composed of an engine(10), a fuel combustion heater(20), a fuel tank(30), an air conditioning system(40), a heater core(41), a fuel filter(100), and a coolant circulation pipe(200). The coolant circulation pipe is wound on the outer circumference of the fuel filter. An inlet of the coolant circulation pipe is connected to a coolant outlet of the fuel combustion heater. An outlet of the coolant circulation pipe is connected to the heater core of the air conditioning system. The heated coolant heats the fuel of the fuel filter by passing the coolant circulation pipe of the fuel filter. The coolant is heated by the fuel combustion heater.
