NONRETURN VALVE INSPECTION

1. Remove the fuel-filler pipe. (See FUEL TANK REMOVAL/INSTALLATION.)

2. Move the valve and verify that the valve opens to 90°.

• If it does not open, replace the fuel-filler pipe.

3. Verify that the nonreturn valve returns to the normal position by spring force.

• If it does not return, replace the fuel-filler pipe.
