• The nonreturn valve cannot be removed because it is fixed to the fuel-filler pipe in the fuel tank.

• 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.
