        NOTE:
        • Remove any foreign matter on the fuel tube joint before performing this work.
        • Do not scratch or allow any foreign matter to get on the parts when disconnecting them as the fuel tube connector has O-rings that seal the pipe (fuel pipe).
        • Be sure to disconnect the fuel tube joint by hand.
        • Do not bend, twist, pinch or kink the nylon tube.
        • Cover the disconnected fuel tube joint with a plastic bag to prevent damage and contamination.

      *e Insertion Point - -
      1. Remove the fuel pump gauge retainer.

        1. Temporarily install SST (plate) and SST (claw) to the fuel pump gauge retainer.

        • SST: 09808-01072 
        • SST: 09808-14031 
          1. 09808-01030
          2. 09808-01090

        HINT: 

        Securely insert the ends of SST (claw) into the insertion points in the fuel pump gauge retainer.

        2. While firmly pressing SST (claw) into the insertion points in the fuel pump gauge retainer, tighten SST (bolt).

        3. Install SST (handle) to SST (plate).

        • SST: 09808-14031 
          1. 09808-01010

        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.

        NOTE:
        • Do not use any tools other than specified as this may result in damage to the fuel pump gauge retainer or fuel tank sub-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 (bolt) and reinstall SST.
