Lexus ES: Installation
INSTALLATION
PROCEDURE
1. INSTALL FUEL SUCTION TUBE WITH PUMP AND GAUGE ASSEMBLY
(a) Install a new fuel suction tube set gasket to the fuel tank assembly.
| (b) Insert the fuel suction tube with pump and gauge assembly to the fuel tank assembly as shown in the illustration. |
|
| (c) Set the part (A) of the fuel suction tube with pump and gauge assembly against the fuel tank assembly, and install 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. |
|
(d) Align the protrusions of the fuel suction tube with pump and gauge assembly with the notches in the fuel tank assembly.

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 09808-01090 SST: 09808-01071 HINT: Securely insert the ends of SST (claw) into the insertion points in the fuel pump gauge retainer. |

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.
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
(a) Push the fuel tube joint onto the plug of the fuel suction plate sub-assembly, then install the tube joint clip.

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.
4. CONNECT FUEL TANK VENT HOSE SUB-ASSEMBLY
(a) Connect the fuel tank vent hose sub-assembly to the fuel suction tube with pump and gauge assembly.
