Disassembly and Assembly

DISASSEMBLY 

1. Disconnect the harness connectors from fuel level sensor unit and fuel temperature sensor.
   NOTE: Hold connector with your fingers, because there is no tab for releasing stopper. Pull it out straight downward.
2. Release the two clips and remove the fuel temperature sensor from the pump assembly.
3. Press in the pawl of fuel level sensor mounting surface.
   CAUTION:

   Be careful not to damage anything.

4. With the pawl disengaged, remove fuel level sensor by sliding it down.
   CAUTION:

   • Be careful not to damage fuel level sensor unit.

   • Do not disassemble fuel filter and fuel pump assembly.

ASSEMBLY 

1. Check for damage of fuel level sensor unit installation position on the side of fuel filter and pump assembly.
2. Slide fuel level sensor unit until it aligns to installation groove, then insert it until it stops.
   • After inserting, apply force in reverse direction (removal direction) to ensure it cannot be pulled out.
3. Press the fuel temperature sensor into the two clips to install it.
4. Connect fuel level sensor unit and fuel temperature sensor harness connectors.

INSPECTION AFTER INSTALLATION 

Use the following procedure to check for fuel leaks.

1. Place ignition to "ON" position (with engine stopped), then check connections for leaks by applying fuel pressure to fuel piping.
2. Start engine and let it idle and check there are no fuel leaks at the fuel system connections.
