PURPOSE: An auxiliary fuel feeding device of a vehicle is provided to prevent a vehicle from turning off by feeding fuel from an auxiliary fuel tank to a main fuel tank in an emergency situation. CONSTITUTION: An auxiliary fuel feeding device contains an auxiliary fuel tank(10) and the auxiliary fuel tank is connected to a main fuel tank(1) through a fuel pipe(11). The main fuel tank is connected to a sub-fuel tank(14) through a U-shaped pipe(13). The U-shaped tank is filled with mercury(15) and a float(16) interlocks with the surface movement of the mercury. A magnet(17) is installed in the upper end of the float and a coil(18) corresponding to the magnet is installed on the outer circumference of the magnet. Thus, the magnet of the float is lifted according to the pressure difference between the main fuel tank and the sub-fuel tank to change impedance from the coil. The change value of the impedance is transmitted to a control unit and the control unit drives a fuel pump(12) of the auxiliary fuel tank.
