The fuel tank overturning valves are essential in case of the car overturning or in the event of a collision, as the valve is able to cut off the flow of fuel.
The Roll over Valve is made of high quality aluminum, it has a ball bearing inside the valve that allows the fuel to pass without any restriction. However, if the tank is turned upside down, the ball bearing falls on top of the valve, effectively cutting off the output.
