摘要： PROBLEM TO BE SOLVED: To provide a fuel supply system capable of simplifying a fuel return pipe while positively preventing vapor lock by constituting to prevent vapor discharged from a pump chamber, from being sucked again into the pump chamber from a fuel inlet.
SOLUTION: A vapor discharge passage 11 led out of the pump chamber 10b of a fuel pump 10 through a vapor jet 10a communicates with the upper part of a fuel tank 2. The vapor produced in the pump chamber 10b in the operation of the fuel pump is thereby pushed out to the vapor discharge passage 11 via the vapor jet 10a and discharged to the upper part of the fuel tank 2 distant from the fuel inlet 10c. Consequently, the vapor is not sucked again into the pump chamber 10b from the fuel inlet 10c, so that the occurrence of vapor lock in the pump chamber 10b can be suppressed to prevent a lowering of pump efficiency.

摘要： PROBLEM TO BE SOLVED: To provide a fuel supply system suppressing discharge of liquefied gas fuel existing in the piping of a fuel supply system into the atmosphere at the time of maintenance.
SOLUTION: Inert gas is introduced from a service port 17 into a supply piping 7 with a liquid phase operating valve 9 closed. Thereby, LPG (liquefied petroleum gas) existing in the supply piping 7, a delivery pipe 4 and a return piping 8 is pushed to flow toward a fuel tank 5 side by inert gas, and recovered into the tank 5. After recovering LPG into the fuel tank 5, the supply piping 7, delivery pipe 4 and return piping 8 are detached for maintenance. Thereby, at this time, discharge of LPG into the atmosphere is suppressed.
