WARNING:
Be sure to read “General Precautions” before working on the fuel system. Refer to FL-3, "
General Pre-
cautions" .
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 fuel level sensor unit
for the top of fuel is above the fuel level sensor unit installation
surface.

As a guide, fuel level becomes the position as shown in the
figure or below when approximately 10 (2-1/4 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-8, "
FUEL TANK" .
c. Insert hose 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-49, "
FUEL PRESSURE RELEASE" (QR20DE
), or EC-392, "
FUEL PRESSURE RELEASE" (VQ23DE and VQ35DE).
3. Open fuel filler lid.
4. Open fuel filler cap and release the pressure inside fuel tank.
5. Remove rear seat cushion. Refer to SE-112, "
REAR SEAT" .

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.

Replace same color retainer as before replacing.

To keep the connecting portion clean and to avoid
damage and foreign materials, cover them completely
with plastic bags or something similar.
8. Using fuel tank lock ring wrench (commercial service tool),
remove lock ring.
9. Remove fuel level sensor unit, fuel filter and fuel pump assem-
bly.
CAUTION:

Do not bend float arm during removal.

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.

PRECAUTIONSPFP:00001
DescriptionBAS0006Z
Observe the following precautions to ensure safe and proper servicing. These precautions are not
described in each individual section.
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
BAS00070
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. Information necessary to service the system safely is included in the SRS and SB section of
this Service Manual.
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 for NATS (NISSAN ANTI-THEFT SYSTEM)BAS00071
NATS will immobilize the engine if someone tries to start it without the registered key of NATS.
Both of the originally supplied ignition key IDs have been NATS registered.
The security indicator is located on the instrument panel. The indicator blinks when the immobilizer system is
functioning.
Therefore, NATS warns outsiders that the vehicle is equipped with the anti-theft system.

When NATS detects trouble, the security indicator lamp lights up while ignition switch is in "ON" position.
This lighting up indicates that the anti-theft is not functioning, so prompt service is required.

When servicing NATS (trouble diagnoses, system initialization and additional registration of other NATS
ignition key IDs), CONSULT-II hardware and CONSULT-II NATS software is necessary.
Regarding the procedures of NATS initialization and NATS ignition key ID registration, refer to CONSULT-
II operation manual, NATS.
Therefore, CONSULT-II NATS software (program card and operation manual) must be kept strictly con-
fidential to maintain the integrity of the anti-theft function.

When servicing NATS (trouble diagnoses, system initialization and additional registration of other NATS
ignition key IDs), it may be necessary to re-register original key identification. Therefore, be sure to
receive all keys from vehicle owner. A maximum of four or five key IDs can be registered into NATS.

When failing to start the engine first time using the key of NATS, start as follows.
1. Leave the ignition key in "ON" position for approximately 5 seconds.
2. Turn ignition key to "OFF" or "LOCK" position and wait approximately 5 seconds.
3. Repeat step 1 and 2 again.
4. Restart the engine while keeping the key separate from any others on key-chain.
