Checking Fuel LinesNBS005R8
Inspect fuel lines, fuel filler cap and fuel tank for improper attach-
ment, leaks, cracks, damage, loose connections, chafing or deterio-
ration.
If necessary, repair or replace damaged parts.
General PrecautionsNBS005R9
WAR NING :
When replacing fuel line parts, be sure to observe the following.
Put a “CAUTION: FLAMMABLE” sign in the workshop.
Be sure to work in a well ventilated area and furnish workshop with a CO2 fire extinguisher.
Do not smoke while servicing fuel system. Keep open flames and sparks away from the work area.
CAUTION:
Use gasoline required by the regulations for octane number. Refer to GI-6, "Precautions for Fuel
(Unleaded Premium Gasoline Required)" .
Before removing fuel line parts, perform out the following procedures:
–Put drained fuel in an explosion-proof container and put the lid on securely. Keep the container in
safe area.
–Release fuel pressure from the fuel lines. Refer to EC-98, "FUEL PRESSURE RELEASE" (VQ35DE)
or EC-809, "
FUEL PRESSURE RELEASE" (VK45DE).
–Disconnect the battery cable from the negative terminal.
Always replace O-ring and clamps with new ones.
Do not kink or twist tubes when they are being installed.
Do not tighten hose clamps excessively to avoid damaging hoses.
After connecting fuel tube quick connectors, make sure
quick connectors are secure.
Ensure that connector and resin tube do not contact any
adjacent parts.
After installing tubes, make sure there is no fuel leakage at
connections in the following steps.
–Apply fuel pressure to fuel lines with turning ignition switch
“ON” (with engine stopped). Then check for fuel leaks at
connections.
–Start engine and rev it up and check for fuel leaks at con-
nections.
Use only a genuine NISSAN fuel filler cap as a replacement.
If an incorrect fuel filler cap is used, the “MIL” may come
on.
For servicing “Evaporative Emission System” parts, refer to
EC-39, "
EVAPORATIVE EMISSION SYSTEM" (VQ35DE) or
EC-749, "
EVAPORATIVE EMISSION SYSTEM" (VK45DE).
For servicing“On Board Refueling Vapor Recovery (ORVR)”
parts, refer to EC-46, "
ON BOARD REFUELING VAPOR
RECOVERY (ORVR)" (VQ35DE) or EC-756, "ON BOARD
REFUELING VAPOR RECOVERY (ORVR)" (VK45DE).

WAR NING :
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-98, "
FUEL PRESSURE RELEASE" (VQ35DE)
or EC-809, "
FUEL PRESSURE RELEASE" (VK45DE).

Fuel hose
When installing fuel hose connector insert them fully until a click
sound of full stopper engagement is heard.
Main and Sub Fuel Level Sensor Unit
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 AssemblyNBS005RD
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:

CautionNES000I6
When installing rubber bushings, the final tightening must be carried out under unladen conditions with
tires on ground. Oil might shorten the life of rubber bushings. Be sure to wipe off any spilled oil.
–Unladen conditions mean that fuel, engine coolant and lubricant are full. Spare tire, jack, hand tools and
mats are in designated positions.
After servicing suspension parts, be sure to check wheel alignment.
Self-lock nuts are not reusable. Always use new ones when installing. Since new self-lock nuts are pre-
oiled, tighten as they are.

On-Vehicle Inspection and ServiceNES000IA
Make sure the mounting conditions (looseness, back lash) of each component and component conditions
(wear, damage) are normal.
INSPECTION OF 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. Do not damage the installation position by applying
excessive force.
SHOCK ABSORBER INSPECTION
Check for oil leakage, damage and breakage of installation positions.
Wheel Alignment InspectionNES000IB
DESCRIPTION
Measure wheel alignment under unladen conditions.
NOTE:
“Unladen conditions” means that fuel, engine coolant, and lubricant are full. Spare tire, jack, hand tools and
mats are in designated positions.
PRELIMINARY CHECK
Check the following:
1. Tires for improper air pressure and wear.
2. Road wheels for runout. Refer to WT-6, "
ROAD WHEEL" .
3. Wheel bearing axial end play. Refer to FAX-5, "
WHEEL BEARING INSPECTION" .
4. Transverse link ball joint axial end play. Refer to FSU-14, "
INSPECTION AFTER REMOVAL" .
5. Shock absorber operation.
6. Each mounting part of axle and suspension for looseness and deformation.
7. Each of suspension member, shock absorber, upper link and transverse link for cracks, deformation and
other damage.
8. Vehicle height (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)
