FUEL SYSTEM
Checking Fuel LineINFOID:0000000001722976
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 PrecautionINFOID:0000000001722977
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 CO
2 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-45, "
Precaution for Fuel
(Unleaded Regular Gasoline Recommended)".
 Before removing fuel line parts, perform the following procedures:
- Release fuel pressure from the fuel lines if necessary. Refer to EC-379, "
Inspection" (HR16DE with
Euro-OBD), EC-681, "
Inspection" (HR16DE without Euro-OBD), EC-1035, "Inspection" (MR18DE).
- 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-379, "
Inspection" (HR16DE with
Euro-OBD), EC-683, "
Inspection" (HR16DE without Euro-OBD), EC-1037, "Inspection" (MR18DE).

FUEL TANK
 Install fuel filler hose (2) to fuel filler tube (1), paying attention to
install mark. Marking faces rightward.
 Insert filler hose to the length below.
 When installing clamp, do not allow clamp to contact the bulge
(bump) part of the tube.
 Tighten the clamp of filler hose so that the remaining length of the
screw becomes the following.
EVAP Hose
1. Check connections for damage or foreign material.
2. Align the matching side connection part with the center of shaft,
and insert connector straight until it clicks.
3. After connecting, pull out quick connector and centralized under-
floor piping by hand. Make sure connections are secure.
Installation of Fuel Tank Mounting Strap
 Install them in the proper position by referring to the identification stamp mark “R” and “L1” on the end.
INSPECTION AFTER INSTALLATION
Use the following procedure to check for fuel leaks.
1. Turn ignition switch “ON” (without starting the engine), to check the connections for fuel leaks with the
electric fuel pump applying pressure to the fuel piping.
2. Start the engine and let it idle to check that there are no fuel leaks at the fuel system connections. : 35mm (1.38 in)

9. Support center of fuel tank (1) with transmission jack (A).
CAUTION:
Securely support the fuel tank with a suitable tool (B).
10. Remove fuel tank mounting straps.
11. Lower transmission jack carefully to remove fuel tank while sup-
porting it by hand. Perform the following works at the same time.
 Pull out vent hose from through hole of vehicle.
 Avoid interference with tank by pulling parking brake cable by
hand.
CAUTION:
Fuel tank may be in an unstable position because of the
shape of fuel tank bottom. Be sure to support tank securely.
INSTALLATION
Installation is in the reverse order of removal.
EVAP Hose
1. Check connections for damage or foreign material.
2. Align the mating side connection part with the center of shaft,
and insert connector straight until it clicks.
3. After connecting, pull out quick connector by hand. Make sure
connections are secure.
Installation of Vent Hose
 Push vent hose into through hole of vehicle.
 Insert vent hose into vent rubber hose, and secure it with clamp.
Installation of Fuel Tank Mounting Strap

Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000001716875
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 SR 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 performed by
an authorized NISSAN/INFINITI dealer.
 Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal
injury caused by unintentional activation of the system. For removal of Spiral Cable and Air Bag
Module, see the SR 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 har-
ness connectors.
Precaution for Procedure without Cowl Top CoverINFOID:0000000001716876
When performing the procedure after removing cowl top cover, cover
the lower end of windshield.
CautionsINFOID:0000000001716877
 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.
