Fuel Tank One Way Valve: Testing and Inspection

NONRETURN VALVE INSPECTION

1. Remove the nonreturn valve. (See FUEL TANK REMOVAL/INSTALLATION.)




2. Verify that the nonreturn valve opens up to 90 ° when it is pushed from the fuel-filler pipe side, and it returns to the normal position by the spring force.
- If the nonreturn valve does not open up to 90 ° or does not return to the normal position, replace the nonreturn valve.
