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

FUEL SYSTEM

FUEL SYSTEM Checking Fuel Lines 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 Precautions WARNING:
When replacing fuel line parts, be sure to observe the following.
Put a “CAUTION: FLAMMABLE” sign in the work area.
Be sure to work in a well ventilated area and have a CO2 fire extinguisher.
Do not smoke while working on the 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-5, “Precautions for Fuel
(Unleaded Regular Gasoline Recommended)” .
Before removing fuel line parts, perform the following procedures:
Release fuel pressure from the fuel lines. Refer to EC-81, “FUEL PRESSURE RELEASE” .
Disconnect the battery ground cable.
Always replace O-rings and clamps with new ones.
Do not kink or twist tubes when they are being installed.
Perform work on level surface.
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 by turning ignition switch ON (without starting the engine). Then check for fuel leaks at the fuel tube connections.
Start engine and rev it up and check for fuel leaks at connections.
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-31, “EVAPORATIVE EMISSION SYSTEM” .
For servicing “On Board Refueling Vapor Recovery (ORVR)” parts, refer to EC-38, “ON BOARD REFUELING VAPOR RECOVERY (ORVR)” .

Removal and Installation REMOVAL

WARNING: Be sure to read “General Precautions” before working on the fuel system. Refer to FL-4, “General Pre- cautions”1. Check fuel level with the vehicle on a level surface. If the fuel gauge indicates more than the level as shown (7/8 full), drain fuel from the fuel tank until the fuel gauge indicates level as shown (7/8 full).

NOTE:
Fuel will be spilled when removing fuel pump assembly if fuel level is above the fuel pump assembly installation surface.
As a guide, fuel level is at the level as shown or below when approximately 12 (3 1/8 US gal, 2 5/8 Imp gal) of fuel is drained from a full fuel tank.
In case fuel pump does not operate, perform the following procedure.
a. Insert fuel tubing of less than 25 mm (0.98 in) in diameter into fuel filler tube through fuel filler opening to drain fuel from fuel filler tube.
b. Disconnect fuel filler hose from fuel filler tube. Refer to FL-9, “FUEL TANK” .
c. Insert fuel tubing into fuel tank through fuel filler hose to drain fuel from fuel tank.
2. Open fuel door and unscrew the fuel filler cap to release the pressure inside the fuel tank.
3. Release the fuel pressure from the fuel lines. Refer to EC-81, “FUEL PRESSURE RELEASE” .
4. Remove rear seat bottom. Refer to SE-14, “REAR SEAT” .
5. Turn the four retainers 90° in a clockwise direction and remove the fuel pump inspection hole cover.

6. Disconnect electrical connector (A) and fuel feed hose quick connector (B). Fuel feed hose (1) Vehicle front
Disconnect the quick connector using the following procedure. Hold the sides of the connector, push in tabs and pull out the tube. If quick connector and tube on fuel pump assembly are stuck, push and pull several times until they move. Disconnect them by pulling.
CAUTION: The tube can be removed when the tabs are completely depressed. Do not twist it more than necessary. Do not use any tools to remove the quick connector. Keep resin tube away from heat. Be especially careful when welding near the resin tube. Prevent acid liquid such as battery electrolyte, from getting on resin tube. Do not bend or twist resin tube during installation and removal. To keep the connecting portion clean, free of foreign materials and to avoid damage, cover them completely with plastic bags or something similar. Do not insert plug to prevent damage to O-ring in quick connector.
7. Remove the lock ring using Tool as shown. Tool number : KV991J0090 (J-46214)

8. Remove fuel level sensor unit, fuel filter and fuel pump assembly (1).
CAUTION:
Do not bend float arm during removal.
Do not allow foreign materials to fall into fuel tank. Use a lint free cloth when handling compo- nents.
Avoid impacts such as dropping when handling components.
