Checking Fuel LinesNBS004IG
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 PrecautionsNBS004IH
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.
CAUTION:
Use gasoline required by the regulations for octane number. Refer to GI-6, "Precautions for Fuel
(Unleaded Premium Gasoline Recommended)" .
Before removing fuel line parts, carry out the following procedures:
–Put drained fuel in an explosion-proof container and put the lid on securely. Keep the container in
safe area.
–Release fuel pressure from the fuel lines. Refer to EC-85, "FUEL PRESSURE RELEASE" (VQ35DE)
or EC-747, "
FUEL PRESSURE RELEASE" (VK45DE).
–Disconnect negative battery terminal.
Always replace O-ring and clamps with new ones.
Do not kink or twist tubes when they are being installed.
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-38, "
EVAPORATIVE EMISSION SYSTEM" (VQ35DE) or
EC-700, "
EVAPORATIVE EMISSION SYSTEM" (VK45DE).
For servicing“On Board Refueling Vapor Recovery (ORVR)”
parts, refer to EC-45, "
ON BOARD REFUELING VAPOR
RECOVERY (ORVR)" (VQ35DE) or EC-707, "ON BOARD
REFUELING VAPOR RECOVERY (ORVR)" (VK45DE).

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 let it idle and make sure there are no fuel leaks at the fuel system connections.
ComponentsNBS004IJ
Disassembly and AssemblyNBS005S3
CAUTION:
Sub fuel level sensor unit cannot be disassembled and should be replaced as a unit.
DISASSEMBLY
Remove fuel level sensor unit as follows.
1. Disconnect harness connector.
Hold connector by fingers and pull it out, because there is no
stopper release tab.
2. Using suitable tool, pull up tabs points as shown in the figure (two points) to release the lock.
CAUTION:
Be careful not to damage it.
3. After fixing tabs are disengaged, slide fuel level sensor unit out in direction shown by the arrow.
CAUTION:
Do not disassemble fuel filter and fuel pump assembly.

10. Disconnect fuel filler hose, vent hose and EVAP hoses at fuel
tank side.
11. Support the lower part of fuel tank with transmission jack. CAUTION:
Support the position that fuel tank mounting bands do not
engage.
12. Remove fuel tank mounting bands.
13. 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.
14. Remove fuel filler tube protector and fuel filler tube, if necessary.
INSTALLATION
Note 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.
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
Revision: 2006 July 2007 FX35/FX45
PRECAUTIONSPFP:00001
CautionNES000FK
When installing rubber bushings, final tightening must be carried out 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. Spare tire, jack, hand tools and
mats are in designated positions.
After servicing suspension parts, be sure to check wheel alignment.
Caulking nuts are not reusable. Always use new ones when installing. Since new caulking nuts are pre-
oiled, tighten as they are.
Avoid burden to front cross bar.
