6. Disconnect the fuel level sensor unit, fuel filter and fuel pump
assembly harness connector (C), EVAP hose quick connector
(A), and the fuel feed hose quick connector (B) from the fuel
level sensor unit, fuel filter, and fuel pump assembly.
Remove the quick connector as follows:
• Hold the sides of the connector, push in tabs and pull out the
tube.
• If the connector and the tube are stuck together, push and pull several times until they start to move. Then disconnect them
by pulling.
CAUTION:
• The tube can be removed when the tabs are completely
depressed. Do not twist it more than necessary.
• Do not use any tools to remove the quick connector.
• Keep the resin tube away from heat. Be especially careful
when welding near the tube.
• Prevent acid liquid such as battery electroly te, etc. from getting on the resin tube.
• Do not bend or twist the tube during installation and removal.
• Only when the tube is replaced, remove the remaining retainer on the tube or fuel level sensor,
fuel filter, and fuel pump assembly.
• When the tube or fuel level sen sor, fuel filter, and fuel pump assembly is replaced, also replace
the retainer with a new one (green colored retainer).
• To keep the connecting portio n clean and to avoid dam-
age and foreign materials, cover them completely with
plastic bags or something similar.
7. Remove the lock ring using a socket drive handle and Tool (A). CAUTION:
Discard the lock ring if damaged or distorted.

8. Remove the fuel level sensor, fuel filter, and fuel pump assembly
(A). Remove and discard the O-ring.
CAUTION:
• Do not bend the float arm during removal.
• Discard the O-ring. Do not reuse O-ring.
INSPECTION AFTER REMOVAL
Inspect the fuel level sensor, fuel filter, and fuel pump assembly for any defects and foreign materials. Replace
as necessary.
INSTALLATION
Installation is in the reverse order of removal.
• Install the fuel level sensor, fuel filter, and fuel pump assembly with the fuel feed hose (B) facing the left side of the vehicle as shown.
Use a new O-ring.
CAUTION:
Do not reuse O-ring.
• Connect the quick connector as follows:
- Check the connection for damage or any foreign materials.
- Align the connector with the tube, then insert the connector straight into the tube until a click is heard.
• After the tube is connected, make sure the connection is secure by performing the following checks:
- Pull the tube and the connector to make sure they are securely
connected.

INSPECTION AFTER INSTALLATION
Use the following procedure to check for fuel leaks.
1. Turn ignition switch “ON” (with engine stopped), t hen check connections for fuel leaks by applying fuel
pressure to fuel piping.
2. Start engine, raise idle, and verify there are no fuel leaks at the fuel system connections.

REMOVAL
WARNING:
Read “General Precautions” before wo rking on the fuel system. Refer to FL-2, "General Precaution"
.
NOTE:
When removing components such as hoses, tubes/lines, etc. , cap or plug openings to prevent fluid from spill-
ing.
1. Disconnect the battery negative terminal. Refer to PG-73, "Removal and Installation (Battery)"
.
2. Check the fuel level with the vehicle on a level surface. If the fuel gauge indicates more than the level as shown (1/2 full), drain
the fuel from the fuel tank until the fuel gauge indicates a level at
or below as shown (1/2 full).
• In case the fuel pump does not operate, use the following pro- cedure.
a. Insert fuel tubing of less than 25 mm (0.98 in) diameter into the fuel filler tube through the fuel f iller opening to drain fuel from the
fuel filler tube.
b. Disconnect the fuel filler hose from the fuel filler tube.
c. Insert fuel tubing into the fuel tank through the fuel filler hose to drain fuel from the fuel tank.

• As a guide, if the fuel tank is full the fuel leve
l reaches or is less than the level on the fuel gauge as
shown, when approximately 34 (9 US gal, 7 1/2 Imp gal) of fuel is drained from a full fuel tank.
3. Open the fuel filler cap to release the pressure inside the fuel tank.
4. Release fuel pressure from fuel line. Refer to EC-182, "Work Procedure"
(QR25DE), EC-687, "Work Pro-
cedure" (VQ35DE).
5. Remove rear seat cushion. Refer to SE-36, "Removal and Installation - Seat Assembly"
.
