  Except U.S.A. and CANADA specs.

  

• The rollover valve consists of a float (valve), O-ring, and spring.

  

Operation

• Because the float (valve) is normally open, evaporative gas in the fuel tank is introduced to the charcoal canister.

• When the float (valve) is immersed in the fuel during sudden cornering or vehicle rollover, the passage is blocked by spring force and the ascending force of the float (valve).
