      *a Marked Part

      HINT: 

      • Be sure to use SST (claws) as shown in the illustration.
      • Engage SST (claws) securely with the fuel pump gauge retainer ribs to secure SST.
    2. While securely pressing SST (claws) against the fuel pump gauge retainer ribs, tighten the 4 bolts.
    3. Install SST (handle).
    4. Lightly press down on SST to prevent it from separating from the fuel pump gauge retainer.

      While pressing SST, rotate the handle slowly to loosen the fuel pump gauge retainer.

      NOTE:
      • Do not use any tools other than those specified in this operation.

        Damage to the fuel pump gauge retainer or fuel tank may result.

      • Do not press down on SST excessively as this may make the fuel pump gauge retainer hard to rotate and may damage components.
      • Make sure to rotate SST (handle) horizontally. If SST (handle) is rotated at an angle, SST may come off.
      • Do not spin SST too fast or use an impact wrench as this may result in damage to components.
      • If SST comes off of the fuel pump gauge retainer, loosen SST (bolts) and reinstall SST.
    5. Remove the fuel pump gauge retainer.
    6. Disengage the clamp and separate the fuel tank vent hose sub-assembly from the fuel tank return tube.
