An LPG(Liquefied Petroleum Gas) fuel feeding apparatus is provided to eliminate the necessity of a vaporizer and vaporize LPG fuel regardless of weather condition. An LPG fuel feeding apparatus includes an ultrasonic generator, a filter unit(31), a solenoid valve(32), a regulator(60), a mixer(40), and fuel supply lines(21,22,23). The ultrasonic generator is arranged in a fuel tank(10), and adjusts the vaporization of LPG fuel by using ultrasonic waves. The filter unit filters off foreign substances from LPG fuel. The solenoid valve controls supply of LPG fuel. The regulator received LPG fuel from the solenoid valve, and regulates pressure of the fuel. The mixer receives LPG fuel from the regulator, mixes the fuel and air, and supplies an air-fuel mixture to an engine(50). The fuel supply lines are connected to the fuel tank, the filter unit, the solenoid valve, the regulator, and the mixer.
