• The rollover valve cannot be removed as it is built into the fuel tank.
• The rollover valve consists of a float, and spring.
• The rollover valve utilizes a combination of float weight, spring force, and buoyancy. When the float is sunk in the fuel, the float (valve) closes to block the sealing surface of the passage.
