Revision: 2006 December 2006 FX35/FX45
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.

Disassembly and AssemblyNBS005S3
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.

On-Vehicle Inspection and ServiceNES000I3
Make sure the mounting conditions (looseness, back lash) of each component and component conditions
(wear, damage) are normal.
INSPECTION LOWER BALL JOINT END PLAY
1. Set front wheels in a straight-ahead position. Do not depress brake pedal.
2. Place an iron bar or similar tool between transverse link and steering knuckle.
3. Measure axial end play by prying it up and down.
CAUTION:
Be careful not to damage ball joint boot.
STRUT INSPECTION

Check strut for oil leakage, damage and replace if there are. Refer to FSU-11, "COIL SPRING AND
STRUT" .
Wheel Alignment InspectionNES000I4
DESCRIPTION

Measure wheel alignment under unladen conditions.
NOTE:
Unladen conditions mean that fuel, engine coolant, and lubricant are full. Spare tire, jack, hand tools and
mats are designated positions.
PRELIMINARY CHECK

Check tires for improper air pressure and wear.

Check road wheels for runout.

Check wheel bearing axial end play.

Check ball joint axial end play of compression rod, upper link, and steering knuckle

Check shock absorber operation.

Check each mounting part of axle and suspension for looseness and deformation.

Check each link, rod and member for cracks, deformation and other damage.

Check vehicle posture.
GENERAL INFORMATION AND RECOMMENDATIONS

A four-wheel thrust alignment should be performed.
–This type of alignment is recommended for any NISSAN/INFINITI vehicle.
–The four-wheel “thrust” process helps ensure that the vehicle is properly aligned and the steering wheel is
centered.
–The alignment rack itself should be capable of accepting any NISSAN/INFINITI vehicle.
–The rack should be checked to ensure that it is level.

Make sure the machine is properly calibrated.
–Your alignment equipment should be regularly calibrated in order to give correct information.
–Check with the manufacturer of your specific equipment for their recommended Service/Calibration
Schedule. Axial end play : 0 mm (0 in)
