   *1	Fuel Sender Gauge Assembly	*2	Fuel Sub-tank Sub-assembly
   *a	Protrusion	*b	Notch

   1. Set the fuel suction tube with pump and gauge assembly to the fuel tank assembly.
      NOTE:

      • Be careful not to bend the arm of the fuel sender gauge assembly.
      • To avoid applying excessive force to the tip of the fuel sender gauge assembly, tilt the fuel sub-tank sub-assembly diagonally and insert it into the fuel tank assembly as shown in the illustration.
   2. Align the protrusions of the fuel suction tube with pump and gauge assembly with the notches in the fuel tank assembly.

   *c	SST (Claw)	*d	SST (Handle)
   *e	Insertion Point	*f	Triangle Mark (Fuel Pump Gauge Retainer)
   *g	Triangle Mark (Fuel Tank Assembly)	-	-

   1. Install the fuel pump gauge retainer.

      1. While pressing down on the fuel suction tube with pump and gauge assembly, temporarily install the fuel pump gauge retainer.

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

      • SST: 09808-01071 
      • 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.

      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).

      • SST: 09808-14031 
        1. 09808-01010

      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.

   1. Push the fuel tube joint onto the plug of the fuel suction plate sub-assembly, then install the tube joint clip.
      NOTE:

      • Check that there are no scratches or foreign matter around the connecting parts of the fuel tube joint and plug before performing this work.
      • Check that the fuel tube joint is securely inserted to the end.
      • Check that the tube joint clip is on the collar of the fuel tube joint.
      • After installing the tube joint clip, check that the fuel tank main tube sub-assembly is securely connected by pulling on it.

   1. Install the fuel tank cover to the fuel tank assembly.

      HINT: 

      Because the fuel tank cover is larger than the service hole, install it while bending it.

   2. Lightly pull the 3 protrusions in the illustration and check that the fuel tank cover is securely installed to the fuel tank assembly.
