• The nonreturn valve is built into the fuel-filler pipe of the fuel tank.
• The nonreturn valve cannot be removed because it is integrated with the fuel tank. Replace the fuel tank if the nonreturn valve requires replacement.
• Under normal conditions, this valve is closed as shown by the dotted line. When refueling, it opens to the position shown by the solid line due to the flow of fuel. When refueling is finished, the valve returns to the normal valve position due to spring force.
