CAUTION:
-
Never perform work on fuel system components near any possible ignition sources.

- Vaporized fuel could ignite, resulting in a serious accident.
-
Do not perform work on fuel system components without first disconnecting the cable from the negative (-) auxiliary battery terminal.

- Sparks could cause vaporized fuel to ignite, resulting in a serious accident.
NOTICE:
- After the power switch is turned off, the radio receiver assembly records various types of memory and settings. As a result, after turning the power switch off, make sure to wait at least 85 seconds before disconnecting the cable from the negative (-) auxiliary battery terminal. (for Audio and Visual System)
- After the power switch is turned off, the radio receiver assembly records various types of memory and settings. As a result, after turning the power switch off, make sure to wait at least 85 seconds before disconnecting the cable from the negative (-) auxiliary battery terminal. (for Navigation System)
PROCEDURE
1. PRECAUTION
NOTICE:
After turning the power switch off, waiting time may be required before disconnecting the cable from the negative (-) auxiliary battery terminal. Therefore, make sure to read the disconnecting the cable from the negative (-) auxiliary battery terminal notices before proceeding with work.

5. REMOVE REAR FLOOR SERVICE HOLE COVER
| (a) Using a clip remover with its tip wrapped with protective tape, remove the rear floor service hole cover and butyl tape. |
|
| (b) Disconnect the 2 fuel suction tube with pump and gauge assembly connectors and fuel tank pressure sensor (vapor pressure sensor) connector. |

7. DISCONNECT FUEL TANK VENT HOSE SUB-ASSEMBLY
| (a) Disconnect the fuel tank vent hose sub-assembly from the fuel suction tube with pump and gauge assembly. Click here |
|
8. DISCONNECT FUEL TANK MAIN TUBE SUB-ASSEMBLY
(a) Remove the tube joint clip, and pull off the fuel tube joint of the fuel tank main tube sub-assembly.
| *1 | Fuel Suction Plate Sub-assembly |
| *2 | Tube Joint Clip |
| *3 | Fuel Tank Main Tube Sub-assembly |
| *a | Fuel Tube Joint |
| *b | O-ring |
| *c | Nylon Tube |

NOTICE:
- 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.
- If the fuel tube joint and fuel suction plate sub-assembly are stuck, push and pull to release them.
9. REMOVE FUEL PUMP GAUGE RETAINER
| (a) Disengage the claw to remove the No. 1 fuel tube clamp. |
|
(b) Remove the fuel pump gauge retainer.
| (1) 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. |
|
(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 09808-01010 SST: 09808-01071 |
|
(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.
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.
(5) While pressing down on the fuel suction tube with pump and gauge assembly, remove the fuel pump gauge retainer.
10. REMOVE FUEL SUCTION TUBE WITH PUMP AND GAUGE ASSEMBLY
| (a) Raise the fuel suction tube with pump and gauge assembly. |
|
(b) Set the part (A) of the fuel suction tube with pump and gauge assembly against the fuel tank assembly, and remove the fuel suction tube with pump and gauge assembly from the fuel tank assembly as shown in the illustration.
NOTICE:
Be careful not to bend the arm of the fuel sender gauge assembly.
| (c) Remove the fuel suction tube set gasket from the fuel tank assembly. |
