2. INSTALL FUEL PUMP GAUGE RETAINER

(a) 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: 09808-14031 09808-01030 09808-01050 SST: 09808-01071 HINT: Securely insert the ends of SST (claw) into the insertion points in the fuel pump gauge retainer.

(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.

NOTICE:

• 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.

(b) Engage the claw to install the No. 1 fuel tube clamp.

3. CONNECT FUEL TANK MAIN TUBE SUB-ASSEMBLY
