Abstract: The spilled fuel collection system is configured for use with the fuel vent of a vessel. The fuel vent is designed to release gas and fuel during an event selected from the group consisting of: a) a build-up of gas pressure within the fuel tank; and, b) overfilling the fuel tank with fuel. The spilled fuel collection system is an accessory that captures fuel and fuel vapors that escape through the fuel vent of a vessel during the fueling process. The spilled fuel collection system comprises a transportable fuel container, a hose, and a quick connect fitting. The transportable fuel container captures the fuel and vapor that escape through the fuel vent. The hose transports the escaped fuel and vapor from the fuel vent into the transportable fuel container. The quick connect fitting secures the hose to the fuel vent.
