To keep the quick connector clean and to avoid damage
and contamination from foreign materials, cover the
quick connector with plastic bags or suitable material as
shown.      

13. Lower the fuel tank using a suitable lift jack and remove the fuel tank.

14. Disconnect the EVAP hose from the fuel pump and remove the EVAP hose from the molded clip in the top

of the fuel tank.

15. Remove the lock ring using Tool.

16. Remove the fuel level sensor, fuel filter, and fuel pump assem-

bly.

CAUTION:

●

Do not bend the float arm during removal.

●

Avoid impacts such as dropping when handling the com-
ponents.

INSTALLATION

Installation is in the reverse order of removal.

●

Connect the quick connector as follows:

–

Check the connection for any damage or foreign materials.

–

Align the connector with the pipe, then insert the connector straight into the pipe until a click is heard.

–

After connecting the quick connector, make sure that the con-
nection is secure by checking as follows:

–

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

–

Visually inspect the connector to make sure the two retainer tabs
are securely connected.

CAUTION:

●

Do not bend the float arm during installation.

●

Avoid impacts such as dropping when handling the compo-
nents.

INSPECTION AFTER INSTALLATION

1.

Turn the ignition switch ON but do not start engine, then check the fuel pipe and hose connections for
leaks while applying fuel pressure.

2.

Start the engine and rev it above idle, then check that there are no fuel leaks at any of the fuel pipe and
hose connections.

PRECAUTIONS

PRECAUTIONS

PFP:00001

Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT 
BELT PRE-TENSIONER”

EES002BN

The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS
system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front
air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the SRS and SB section of this Service Man-
ual.

WARNING:

●

To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death
in the event of a collision which would result in air bag inflation, all maintenance must be per-
formed by an authorized NISSAN/INFINITI dealer.

●

Improper maintenance, including incorrect removal and installation of the SRS, can lead to per-
sonal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air
Bag Module, see the SRS section.

●

Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or
harness connectors.

Precautions

EES0022O

●

When installing the rubber bushings, the final tightening must be done under unladen condition and with
the tires on level ground. Oil will shorten the life of the rubber bushings, so wipe off any spilled oil immedi-
ately.

●

Unladen condition means the fuel tank, engine coolant and lubricants are at the full specification. The
spare tire, jack, hand tools, and mats are in their designated positions.

●

After installing suspension components, check the wheel alignment.

●

Lock nuts are not reusable. Always use new lock nuts for installation. New lock nuts are pre-oiled, do not
apply any additional lubrication.

ON-VEHICLE SERVICE

PFP:00000

Front Suspension Parts

EES0022T

Check front suspension parts for excessive play, cracks, wear and
other damage.

●

Shake each front wheel to check for excessive play. If looseness
is noted:

–

inspect wheel bearing end play. Refer to 

FAX-5, "WHEEL

BEARING INSPECTION"

 .

–

check ball joint end play. Refer to 

FSU-15, "Inspection"

 .

●

Make sure that the cotter pin is inserted in drive shaft end (4WD
only).

●

Retighten all nuts and bolts to the specified torque.

●

Check shock absorber for oil leakage and other damage.

●

Check suspension ball joint for grease leakage and ball joint
dust cover for cracks and other damage.

Front Wheel Alignment

EES0022U

PRELIMINARY INSPECTION

WARNING:

Always adjust the alignment with the vehicle on a flat surface.

NOTE:
If alignment is out of specification, inspect and replace any damaged or worn rear suspension parts before
making any adjustments.

1.

Check and adjust the wheel alignment with the vehicle under unladen conditions. “Unladen conditions”
means that the fuel, coolant, and lubricant are full; and that the spare tire, jack, hand tools and mats are in
their designated positions.

2.

Check the tires for incorrect air pressure and excessive wear.

3.

Check the wheels for run out and damage. Refer to 

WT-5, "Inspection"

 .

4.

Check the wheel bearing axial end play. Refer to 

FAX-5, "WHEEL BEARING INSPECTION"

 .

5.

Check the shock absorbers for leaks or damage.

6.

Check each mounting point of the suspension components for any excessive looseness or damage.

7.

Check each link, arm, and the suspension member for any damage.

8.

Check the vehicle height. Refer to 

FSU-21, "Wheelarch Height (Unladen*

1

 )"

 .

GENERAL INFORMATION AND RECOMMENDATIONS

1.

A Four-Wheel Thrust Alignment should be performed.

●

This type of alignment is recommended for any NISSAN vehicle.

●

The four-wheel “thrust” process helps ensure that the vehicle is properly aligned and the steering wheel
is centered.

●

The alignment machine itself should be capable of accepting any NISSAN vehicle.

●

The alignment machine should be checked to ensure that it is level.

2.

Make sure the alignment machine is properly calibrated.
