FUEL SHUT-OFF VALVE CONSTRUCTION/OPERATION [LF]
E5U011642990N02
• The fuel shut-off valve is built into the fuel tank.
• The fuel shut-off valve mainly consists of a valve, float, spring, and by-pass valve.
• 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.
