FUEL SHUT-OFF VALVE CONSTRUCTION/OPERATION [L8, LF, L3]
id0116a4150700
• During refueling or due to fuel sloshing, the float is flooded with fuel and the floating force causes the valve to close. Also, during vehicle rollover, the valve closes due to balance between the float gravity and spring.
• The float rises during refueling, locks after refueling is completed, and is returned to its original position due to the evaporative emissions flowing from the bypass valve. Due to this, the evaporative emissions in the fuel tank can be released through the charcoal canister.
