      2. While firmly pressing the SST (claws) into the insertion points in the fuel pump gauge retainer, tighten the SST (bolts).
      3. Install SST (handle).
      4. Lightly press down on SST to prevent it from separating from the fuel pump gauge retainer. While pressing down on SST, rotate SST (handle) slowly to loosen the fuel pump gauge retainer.
        • SST: 09808-0107109808-14030 
          1. 09808-01010
          2. 09808-01020

        • Do not use any tools other than specified in this operation as this may result in damage to the fuel pump gauge retainer or the fuel tank assembly.
        • 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 it 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.
