A vacuum fluid transfer system transfers a fluid by having inside of a main pipe line (10) vacuum and using a pressure difference. The system includes a portion where the main pipe line (10) is horizontally arranged, and is provided with an automatic suction valve (17) and a terminal automatic suction valve (16) for introducing atmosphere into the main pipe line (10) from the outside of the main pipe line (10) when a degree of vacuum inside the main pipe line (10) is reduced to a prescribed value or lower. |
