PURPOSE: An LNG fuel supply system is provided to keep LNG levers of different tanks uniformly by a time relay valve and to supply the LNG steadily. CONSTITUTION: An LNG fuel supply system comprises a second LNG tank(105), a connection line(10), a charging line(20), a vent line(40), a series line(30) and a supply line(50). The second LNG tank separates from a first LNG tank(100). The connection line interlinks the first LNG tank and the second LNG tank. A time relay valve(140) is arranged in middle of the connection line One side of the charging line is connected to the fuel supply part and the other side is connected to the first LNG tank. One side of the vent line is connected to the second LNG tank and the other side is opened. The series line interlinks the first LNG tank and the second LNG tank. The supply line is branched from one side of the connection line and supplies LNG to the engine. The time relay valve is opened for the fixed hour. The amount of LNG filled in the first and second LNG tanks uniformly kept.
