Disclosed is a fuel gas supply system. The fuel gas supply system according to the present invention includes: a storage tank storing liquefied gas and evaporation gas generated therefrom; a first supply line provided with a first compression unit and extending from the storage tank to a customer; a re-liquefaction line branching from the first supply line and supplied with and re-liquefying some of a fluid pressurized by the first compression unit; a gas-liquid separator supplied with the fluid through the re-liquefaction line and separating the fluid into flash gas and a liquid component; a second supply line supplying some of the flash gas to the customer from the gas-liquid separator; a re-supply line supplying some of the flash gas to the first supply line from the gas-liquid separator; a heat exchanger performing heat exchange between the first supply line and the re-liquefaction line; a flow rate adjustment valve provided on the second supply line and controlled based on the pressure value of the storage tank; and a pressure adjustment valve provided on the re-supply line and controlled based on the pressure value of the gas-liquid separator.
