      NOTE:
      • Be careful not to bend the arm of the fuel sender gauge assembly.
      • Make sure the horizontal angle of the fuel suction plate sub-assembly is less than 90°.
      • To avoid applying excessive force to the tip of the fuel sender gauge assembly, tilt the No. 1 fuel sub-tank diagonally and insert it into the fuel tank assembly as shown in the illustration.

        *a Insertion Point
        *b SST (Plate)
        *c SST (Claw)
        *d SST (Bolt)

        HINT: 

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

      3. While firmly pressing SST (claw) into the insertion points in the fuel pump gauge retainer, tighten SST (bolt).
      4. Install SST (handle) to SST (plate).

        *a Triangle Mark (Fuel Pump Gauge Retainer)
        *b Triangle Mark (Fuel Tank Assembly)
        *c SST (Handle)
        *d SST (Plate)
        *e SST (Claw)
        *f SST (Bolt)
        Front Side
        • SST: 09808-14031 
          1. 09808-01010
          2. 09808-01030
          3. 09808-01090
        • SST: 09808-01071 
      5. Using SST, rotate the fuel pump gauge retainer so that the triangle mark on the fuel pump gauge retainer is aligned with the triangle mark on the fuel tank assembly to install the fuel suction tube with pump and gauge assembly to the fuel tank assembly.
        NOTE:
        • Do not use any tools other than specified as this may result in damage to the fuel pump gauge retainer or 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 (bolt) and reinstall SST.
        • Make sure that the fuel suction tube set gasket does not come off.
    2. Engage the claw to install the No. 1 fuel tube clamp.
  3. CONNECT FUEL TANK MAIN TUBE SUB-ASSEMBLY 
    1. Push the fuel tube joint onto the plug of the fuel suction plate sub-assembly, then install the tube joint clip.
