PURPOSE: A fuel leakage warning device of a fuel line is provided to warn a driver of fuel leakage when fuel leaks out by breakage of the fuel line while fuel is supplied from a fuel pump to an injector along the fuel line. CONSTITUTION: A fuel leakage warning device of a fuel line(20) comprises a turbulence producer(40) formed to a starting part of the fuel line of a side connected to a fuel tank(21); ultrasonic transmitters(31) formed to the rear of the turbulence producer and to the end of the fuel line to which an injector(22) is connected, to send ultrasonic waves; ultrasonic receivers(33,34) installed to directions corresponding to the ultrasonic transmitters, to receive ultrasonic waves produced from the ultrasonic transmitters; an electronic control unit(50) comparing and analyzing the frequency of the turbulence received together with ultrasonic waves via the ultrasonic receivers and deciding whether fuel leaks out of the fuel line; and a warning unit(54) warning a driver of the decided result of the electronic control unit.
