The Oberg Fuel Line Safety Valve is your first line of defense against a siphon fire in the event of an accident. This revolutionary, technically advanced in-line valve opens from the vacuum created by the fuel pump. There is no flow restriction whatsoever. When the engine stops the valve closes instantly stopping the flow of fuel. In the event that the fuel pump is knocked off or the fuel line is severed, the valve will close preventing siphoning from the fuel cell. This also prevents fire from seeking the fuel cell through the severed line. Your safety is the #1 priority.
