WARNING:
Read “General Precautions” when working on the fuel system. Refer to FL-3, "
General Precautions" .
1. Check fuel level on fuel gauge. If fuel gauge indicates more than the level as shown in the figure (full or almost full), drain fuel
from fuel tank until fuel gauge indicates level as shown in the fig-
ure or below.
NOTE:
Because fuel will be spilled when removing main and sub fuel
level sensor units for the top of the fuel is above the main and
sub fuel level sensor units installation surface.

As a guide, fuel level becomes the position as shown in the
figure or below when approximately 20 (5-1/4 US gal, 4-3/8
Imp gal) of fuel are drained from fuel tank.

In a case that fuel pump does not operate, perform the follow-
ing procedure.
a. Insert hose of less than 25 mm (0.98 in) in diameter into fuel filler tube through fuel filler opening to draw fuel from fuel filler tube.
b. Disconnect fuel filler hose from fuel filler tube. Refer to FL-10, "
FUEL TANK" .
c. Insert fuel tube into fuel tank through fuel filler hose to draw fuel from fuel tank.
2. Release the fuel pressure from the fuel lines. Refer to EC-99, "
FUEL PRESSURE RELEASE" (VQ35DE)
or EC-789, "
FUEL PRESSURE RELEASE" (VK45DE).
3. Open fuel filler lid.

4. Open filler cap and release the pressure inside fuel tank.
5. Remove rear seat cushion. Refer to SE-106, "
REAR SEAT" .
6. Peel off floor carpet, then remove inspection hole cover for main and sub fuel level sensor units by turning clips clockwise by 90
degrees.
7. Disconnect harness connector and fuel feed tube.
Disconnect quick connector as follows:

Hold the sides of connector, push in tabs and pull out tube.

If quick connector sticks to tube of main fuel level sensor unit,
push and pull quick connector several times until they start to
move.Then disconnect them by pulling.

CAUTION:

Quick connector can be disconnected when the tabs
are completely depressed. Do not twist it more than
necessary.

Do not use any tools to disconnected quick connector.

Keep resin tube away from heat. Be especially careful
when welding near the resin tube.

Prevent acid liquid such as battery electrolyte, etc.
from getting on resin tube.

Do not bend or twist resin tube during installation and
disconnection.

Do not remove the remaining retainer on hard tube (or
the equivalent) except when resin tube or retainer is
replaced.

When resin tube or hard tube (or the equivalent) is
replaced, also replace retainer with new one.

To keep the connecting portion clean and to avoid
damage and foreign materials, cover them completely
with plastic bags or something similar.
8. Remove main fuel level sensor unit, fuel filter and fuel pump assembly, and sub fuel level sensor unit as follows:
CAUTION:

Do not bend float arm during removal.

Avoid impacts such as falling when handling components.
a. Removal of main fuel level sensor unit, fuel filter and fuel pump assembly:
i. Remove retainer.
ii. Raise main fuel level sensor unit, fuel filter and fuel pump assembly, and using snap ring pliers, remove fuel hose connec-
tor.
CAUTION:
Be careful not to damage fuel hose connector by expanding
them excessively.
b. Removal of sub fuel level sensor unit:
i. Remove retainer.
ii. Raise and release sub fuel level sensor unit to remove.
INSTALLATION
Note to the following, and install in the reverse order of removal. Retainer color: White

Main and Sub Fuel Level Sensor Unit

When installing fuel hose connector insert them fully until a click
sound of full stopper engagement is heard.

Face main and sub fuel level sensor units as shown in the fig-
ure, and install them with the knock pin on back aligned with pin
hole on fuel tank.

Install retainer so that its notch becomes parallel with the notch
on fuel tank.

Tighten retainer mounting bolts evenly.
Quick Connector
Connect quick connector as follows:
1. Check the connection for damage or any foreign materials.
2. Align the connector with the tube, then insert the connector straight into the tube until a click sound is heard.
3. After connecting, make sure that the connection is secure by following method.

Pull the tube and the connector to make sure they are
securely connected.

Visually confirm that the two retainer tabs are connected to
the connector.
INSPECTION AFTER INSTALLATION
Use the following procedure to check for fuel leaks.

1. Turn ignition switch “ON” (with engine stopped), then check connections for leaks by applying fuel pres-
sure to fuel piping.
2. Start engine and let it idle and make sure there are no fuel leaks at the fuel system connections.
Disassembly and AssemblyABS005Z0
CAUTION:
Sub fuel level sensor unit cannot be disassembled and should be replaced as a unit.
DISASSEMBLY
Remove fuel level sensor unit as follows.
1. Disconnect harness connector.

Hold connector by fingers and pull it out, because there is no
stopper release tab.
2. Using suitable tool, pull up tabs points as shown in the figure (two points) to release the lock.
CAUTION:
Be careful not to damage it.
3. After fixing tabs are disengaged, slide fuel level sensor unit out in direction shown by the arrow.
CAUTION:
Do not disassemble fuel filter and fuel pump assembly.
