NONRETURN VALVE

NONRETURN VALVE INSPECTION

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

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 through the fuel pump installation hole.

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