Zusammenfassung:	The present invention relates to an LPG direct injecting system directly injecting LPG to a combustion chamber of an engine. According to an embodiment of the present invention, the LPG direct injecting system comprises: an engine receiving fluid LPG in a combustion engine; an injector arranged to directly inject the LPG to the combustion chamber of the engine; a high pressure fuel pump supplying the high pressure LPG to the injector; a fuel tank in which the LPG supplied to the engine is stored; a low pressure fuel pump which is mounted in the fuel tank and which supplies the LPG stored in the fuel tank to the high pressure fuel pump; a regulator device which receives remaining LPG from the high pressure fuel pump, stably controls the pressure of the received remaining LPG, and transfers the predetermined pressure LPG to the fuel tank; a fuel supplying line which connects the low pressure fuel pump and the high pressure fuel pump so as to supply the LPG stored in the fuel tank to the engine; and a fuel return line returning, to the fuel tank, the LPG remaining after pumped in the high pressure fuel pump.
