id0114z2803600

1.  Remove the fuel pump. (See FUEL PUMP UNIT REMOVAL/INSTALLATION [13B-MSP].)

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 through the fuel pump installation hole.

•  If it does not open/close or return to the normal position, replace the fuel tank. (See FUEL TANK REMOVAL/INSTALLATION [13B-MSP].)
