<p>The present invention relates to a liquefied petroleum fuel-injection feeding system for feeding liquefied petroleum gas fuel to an engine, which can comprises a fuel tank filled with liquefied petroleum gas, a pump device arranged at the inner part of the fuel tank and used for feeding liquefied petroleum gas fuel to an engine, and an outer filter arranged at the outer part of the fuel tank and used for filtering foreign matters when the liquefied petroleum gas fuel is adsorbed into the pump device. Therefore, the outer filter can be changed without opening the fuel tank. In addition, when the outer filter is changed, a first valve and a second valve are closed so that the fuel in the container can not be discharged to the outer part. In addition, a suction pipeline is inserted into a prefilter, thereby reducing the suction resistance. Furthermore, the suction pipeline is separated, and the separated parts are connected by flexible tubes, thereby preventing the vibration and noise generated by the pump from being transferred to the fuel tank.</p> |
