- Make sure to correctly assemble the fuel return vent tube sub-assembly as shown in the illustration. If assembled incorrectly, the fuel sender gauge assembly (No. 2 fuel sender gauge assembly) may catch on the fuel return vent tube resulting in incorrect operation of the fuel sender gauge assembly (No. 2 fuel sender gauge assembly) and an incorrect value being displayed on the fuel gauge.
- When connecting the fuel tube connector, do not excessively pull on the fuel return vent tube sub-assembly.
(c) Insert the fuel suction tube with pump and gauge assembly to the fuel tank assembly as shown in the illustration.
NOTICE:
- 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. INSTALL FUEL PUMP GAUGE RETAINER
(a) Install the fuel pump gauge retainer.
(1) While pressing down on the fuel suction with pump and gauge tube 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 09808-01090 SST: 09808-01071 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).

| *b | SST (Plate) |
| *c | SST (Bolt) |
| *d | Triangle Mark (Fuel Pump Gauge Retainer) |
| *e | Triangle Mark (Fuel Tank Assembly) |
| *f | SST (Claw) |
| *g | Insertion Point |
| *h | Extension Bar |
 | Front Side of Vehicle |
SST: 09808-14031
09808-01010
09808-01030
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 with pump and gauge tube 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) Attach the claw and install the No. 1 fuel tube clamp to the fuel pump gauge retainer.
3. INSTALL NO. 1 FUEL TUBE CLAMP
(a) Engage the claw and install the No. 1 fuel tube clamp to the fuel pump gauge retainer.
4. CONNECT FUEL TANK MAIN TUBE SUB-ASSEMBLY
(a) Push the fuel tube joint of the fuel tank main tube sub-assembly, and install the tube joint clip.
| *1 | Plate Sub-assembly | *2 | Tube Joint Clip |
| *3 | Fuel Tank Main Tube Sub-assembly | - | - |
| *a | O-ring | *b | Correct |
| *c | Incorrect | *d | Fuel Tube Joint |
 | Insert |
 | Insert |
NOTICE:
- 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.
5. CONNECT CHARCOAL CANISTER OUTLET HOSE
(a) Connect the charcoal canister outlet hose to the fuel suction with pump and gauge tube assembly.
6. CONNECT FUEL TANK EVAP TUBE SUB-ASSEMBLY
(a) Connect the fuel tank evap tube sub-assembly to the fuel suction with pump and gauge tube assembly.

7. CONNECT NO. 1 FUEL EVAPORATION TUBE SUB-ASSEMBLY
| (a) Connect the No. 1 fuel evaporation tube sub-assembly to the fuel suction with pump and gauge tube assembly, and slide the clamp to secure the tube. |
|
8. INSTALL REAR FLOOR SERVICE HOLE COVER (for LH Side)
(a) Remove any remaining butyl tape from the rear floor service hole cover and body.
(b) Connect the 2 connectors to the fuel suction with pump and gauge tube assembly.
(c) Install the rear floor service hole cover with new butyl tape.
NOTICE:
Securely install the rear floor service hole cover.

Fuel-Filler Lid and Cap
WARNING
When removing the fuel-filler cap, loosen the cap slightly and wait for any hissing to stop, then remove it
Fuel spray is dangerous. Fuel can burn skin and eyes and cause illness if ingested. Fuel spray is released when there is pressure in the fuel tank and the fuel-filler cap is removed too quickly.
