PROBLEM TO BE SOLVED: To provide a fuel supply system capable of effectively inhibiting a siphon phenomenon from greatly reducing the amount of fuel in a reservoir cup so as to reduce the startability of an internal combustion engine.SOLUTION: A fuel supply system includes: a reservoir cup 28 arranged in a fuel tank 21; a feed pump 22 arranged in the reservoir cup 28; a fuel supply passage P1 for guiding fuel discharged from the fuel pump 22 along a supply direction; a return passage P2 for recycling part of the fuel discharged from the feed pump 22 into the fuel tank 21; and a solenoid flow control valve 24 having an inflow port 24a for allowing the fuel passing through the return passage P2 to flow into the reservoir cup 28, and capable of controlling the amount of the fuel to flow into the reservoir cup 28. The inflow port 24a of the solenoid flow control valve 24 is arranged on the high liquid level side of the reservoir cup 28 within a liquid level variation range of the fuel reserved in the reservoir cup 28. |
