Abstract: A fuel spillage containment device is disclosed which is user-friendly and may be mounted to the hull of a boat beneath the fuel vent of the boat for collecting fuel spillage during refueling in a single handed operation. The device may be released and removed from the boat in the same single handed operation in a reliable manner that assures that fuel spillage is prevented from the collector of the device even when nearly full of fuel. The device includes a frame which carries spaced suction cups for affixation to the hull having a release mechanism for releasing the suction cups. The frame is affixed to the collector in a balanced configuration with respect to operation of said handle and release mechanism by means of flexible connector arms which may be bent to a desired position to assure the collector is properly mounted beneath the fuel vent for collecting fuel spillage.
