NONRETURN VALVE INSPECTION

1. Remove the fuel pump. (See FUEL PUMP UNIT REMOVAL/INSTALLATION.)

Note

• The nonreturn valve cannot be removed as it is built into the fuel tank.

• The nonreturn valve is normally closed due to spring force.

2. Verify that the nonreturn valve opens/closes from the fuel pump installation hole.

• If it does not open/close or return to the normal position, replace the fuel tank.
