Checking Fuel LinesBBS005AE
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 PrecautionsBBS005AF
WARNING:
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.

Put drained fuel in an explosion-proof container and put the lid on securely. Keep the container in
safe area.
CAUTION:

Use gasoline required by the regulations for octane number. Refer to GI-6, "Precautions for Fuel" .

Before removing fuel line parts, perform the following procedures:
–Release fuel pressure from the fuel lines. Refer to EC-49, "FUEL PRESSURE RELEASE"
(QR20DE), or EC-392, "FUEL PRESSURE RELEASE" (VQ23DE and VQ35DE).
–Disconnect the battery cable from negative terminal.

Always replace clamps with new ones.

Do not kink or twist tubes when they are being installed.

Perform work on level place.

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-27, "
EVAPORATIVE EMISSION SYSTEM" (QR20DE), or
EC-366, "
EVAPORATIVE EMISSION SYSTEM" (VQ23DE
and VQ35DE).

INSTALLATION
Note the following, and install in the reverse order of removal.
Fuel Level Sensor Unit, Fuel Filter and Fuel Pump Assembly
1. Install seal packing to fuel tank without any twist.
2. Align “B” with “A” as shown in the figure. Install fuel level sensor
unit, fuel filter and fuel pump assembly to fuel tank.
CAUTION:
Do not bend float arm during installing.
3. Tighten lock ring with lock ring wrench (commercial service tool).
CAUTION:
Install lock ring horizontally.
Quick Connector
Connect quick connector of fuel feed hose 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.

Visually confirm that the two tabs are connected to the connector.

Pull the tube and the connector to make sure they are
securely connected.
Inspection Hole Cover
1. Install inspection hole cover with front mark (arrow) facing front of vehicle.
2. Lock clips by turning counter-clockwise.
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 rev it up and make sure there are no fuel leaks at the fuel system connections.

7. Disconnect fuel filler hose and vent hose at the position shown
in the figure.
8. Disconnect EVAP hose at EVAP canister side.
9. Support the lower part of fuel tank with transmission jack.
CAUTION:

Support right and left part of flat bottom plate with pass-
ing board.

Because the height of right and left bottom plate is differ-
ent, horizontally support them with wood plate and things
like that.

Support the position that fuel tank mounting bands do
not engage.
10. Remove fuel tank mounting bands.
11. Supporting with hands, descend transmission jack carefully, and remove fuel tank.
CAUTION:

Make sure that all connection points have been disconnected.

Confirm there is no interference with vehicle.
12. Remove fuel filler tube, if necessary.
INSTALLATION
Note to the following, and install in the reverse order of removal.

Surely clamp fuel hoses and insert hose to the length below.

Be sure hose clamp is not placed on swelled area of fuel tube.

Tighten fuel hose clamp so that the distance between its lugs becomes to the following.

Before fixing fuel tank, temporarily install fuel filler tube.
CAUTION:
Use genuine fuel filler tube mounting bolts or equivalent. Make sure to tighten them to the speci-
fied torque.

To connect quick connector, refer to FL-7, "Quick Connector" .
INSPECTION AFTER INSTALLATION
Use the following procedure to check for fuel leaks.
1. Turn ignition switch “ON” (with engine stopped), and check connections for leakage by applying fuel pres-
sure to fuel piping.
2. Start engine and rev it up and make sure there are no fuel leaks at the fuel system tube and hose connec-
tions.

PRECAUTIONS

PRECAUTIONSPFP:00001
CautionBES0003G

When installing rubber bushings, final tightening must be performed under unladen conditions with tires
on ground. Oil will 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. A spare tire, a jack, hand tools
and mats are in designated positions.

After servicing suspension parts, be sure to check wheel alignment.

Self-lock nut are not reusable. Always use new ones when installing. Since new self-lock nuts are pre-
oiled, tighten as they are.

On-Vehicle Inspection BES0003K
Make sure that the mounting conditions (looseness, back lash) of each component and component status
(wear, damage) are normal.
INSPECTION OF TRANSVERSE LINK BALL JOINT END PLAY
1. Set front wheels in a straight-ahead position. Do not depress brake pedal.
2. Measure axial end play by placing an iron pry bar or a similar item between suspension arm and strut
assembly and prying up and down.
CAUTION:
Be careful not to damage ball joint boot. Do not damage the installation position by applying
excessive force.
STRUT INSPECTION
Check for oil leakage, damage, and breakage of installation positions.
Wheel Alignment InspectionBES0003L
DESCRIPTION
Measure wheel alignment under unladen conditions.
NOTE:
“Unladen” conditions mean that fuel, engine coolant, and lubricant are full. A spare tire, a jack, hand tools and
mats are in designated positions.
PRELIMINARY CHECK
1. Check Tires for improper air pressure and wear.
2. Check Road wheels for runout. Refer to WT-3, "
ROAD WHEEL" .
3. Check Wheel bearing axial end play. Refer to FAX-5, "
WHEEL BEARING INSPECTION" .
4. Check Transverse link ball joint axial end play. Refer to FSU-14, "
INSPECTION AFTER REMOVAL" .
5. Check Strut operation.
6. Check Each mounting point of axle and suspension for looseness and deformation.
7. Check Each link, rod, and member for cracks, deformation and other damage.
8. Check Vehicle height (posture).
INSPECTION OF CAMBER, CASTER AND KINGPIN INCLINATION ANGLES.

Camber, caster, kingpin inclination angles cannot be adjusted.

Before inspection, mount wheels onto turning radius gauge. Mount rear wheels onto a stand that has
same height so vehicle will remain horizontal.
Using a CCK Gauge
Install CCK gauge attachment [SST:KV991040S0] with the following procedure on wheel, then measure wheel
alignment.
1. Remove three wheel nuts, and install the guide bolts to hub
bolts.
2. Screw adapter into the plate until it contacts the plate tightly.
3. Screw center plate into the plate.
4. Insert plate on guide bolt. Put spring in, and then evenly screw
both guide bolt nuts. When fastening guide bolt nuts, do not
completely compress the spring.Axial end play : 0 mm (0 in)
