ROLLOVER VALVE CONSTRUCTION/OPERATION
CHU011642720S02
• The rollover valves are welded in two locations in the evaporative gas path on the top of the fuel tank and
cannot be removed/installed.
• The rollover valve mainly consists of a float and spring.
• When the float is saturated with fuel, the float (valve) closes to shut the sealing surface of the path due to the
weight of the float, spring force, and flotation relationship.
