Disconnect electrical connector (A) and fuel feed hose quick connec-
tor (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.
6. Remove center exhaust tube. Refer to EX-3, "
EXHAUST SYSTEM" .
7. Remove exhaust heat shields.
8. Disconnect parking brake cables (1) from the lower surface of
fuel tank and axle and position the parking brake cables (1) out
of the way.

12. Support center of fuel tank (1) with transmission jack (A).
CAUTION:
Securely support the fuel tank with a suitable tool (B).
13. Remove fuel tank bands (RH and LH).
14. Lower transmission jack carefully to remove fuel tank while sup-
porting it 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 Canister
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.
Pull the tube and the connector to make sure they are securely connected.
Fuel Tank Band
Install them in the proper position by referring to the identification stamp mark “R” and “L” on the end.
Fuel Filler Hose
Insert fuel filler hose to the length below.
Be sure hose clamp is not placed on swelled area of fuel filler tube.
EVAP Hose
1. Check connections for damage or foreign material.
2. Align the matching quick connector (A) with the center of EVAP
hose (1), and insert quick connector (A) straight until it clicks.
3. After connecting, pull on quick connector (A) and EVAP hose (1)
by hand. Make sure connections are secure.
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.

Revision: June 20062007 Versa
To prevent serious burns:
Avoid contact with hot metal parts.
Do not remove the radiator cap when the engine is hot.
Dispose of or recycle drained oil or the solvent used for cleaning
parts in an appropriate manner.
Do not attempt to top off the fuel tank after the fuel pump nozzle
shuts off automatically.
Continued refueling may cause fuel overflow, resulting in fuel
spray and possibly a fire.
Clean all disassembled parts in the designated liquid or solvent
prior to inspection or assembly.
Replace oil seals, gaskets, packings, O-rings, locking washers, cotter pins, self-locking nuts, etc. with new
ones.
Replace inner and outer races of tapered roller bearings and needle bearings as a set.
Arrange the disassembled parts in accordance with their assembled locations and sequence.
Do not touch the terminals of electrical components which use microcomputers (such as ECM).
Static electricity may damage internal electronic components.
After disconnecting vacuum or air hoses, attach a tag to indicate the proper connection.
Use only the fluids and lubricants specified in this manual.
Use approved bonding agent, sealants or their equivalents when required.
Use hand tools, power tools (disassembly only) and recom-
mended special tools where specified for safe and efficient ser-
vice repairs.
When repairing the fuel, oil, water, vacuum or exhaust systems,
check all affected lines for leaks.
Before servicing the vehicle:
Protect fenders, upholstery and carpeting with appropriate cov-
ers.
Take caution that keys, buckles or buttons do not scratch paint.
WA RN ING:
To prevent ECM from storing the diagnostic trouble codes, do not carelessly disconnect the harness
connectors which are related to the engine control system and TCM (transmission control module)
system. The connectors should be disconnected only when working according to the WORK FLOW of
TROUBLE DIAGNOSES in EC and AT sections.
Precautions for Three Way CatalystEAS001ZB
If a large amount of unburned fuel flows into the catalyst, the catalyst temperature will be excessively high. To
prevent this, follow the instructions.
Use unleaded gasoline only. Leaded gasoline will seriously damage the three way catalyst.
When checking for ignition spark or measuring engine compression, make tests quickly and only when
necessary.
SGI233
PBIC0190E
SGI234
GI-6
PRECAUTIONS
Revision: June 20062007 Versa
Do not run engine when the fuel tank level is low, otherwise the engine may misfire, causing damage to
the catalyst.
Do not place the vehicle on flammable material. Keep flammable material off the exhaust pipe and the three
way catalyst.
Precautions for Fuel (Unleaded Regular Gasoline Recommended)EAS00209
Use unleaded regular gasoline with an octane rating of at least 87 AKI (Anti-Knock Index) number (Research
octane number 91).
CAUTION:
Do not use leaded gasoline. Using leaded gasoline will damage the three way catalyst. Using a fuel
other than that specified could adversely affect the emission control devices and systems, and could
also affect the warranty coverage validity.
Precautions for Multiport Fuel Injection System or Engine Control SystemEAS001ZD
Before connecting or disconnecting any harness connector for
the multiport fuel injection system or ECM:
Turn ignition switch to “OFF” position.
Disconnect negative battery terminal.
Otherwise, there may be damage to ECM.
Before disconnecting pressurized fuel line from fuel pump to
injectors, be sure to release fuel pressure.
Be careful not to jar components such as ECM and mass air
flow sensor.
Precautions for HosesEAS001ZE
HOSE REMOVAL AND INSTALLATION
To prevent damage to rubber hose, do not pry off rubber hose
with tapered tool or screwdriver.
To reinstall the rubber hose securely, make sure that hose inser-
tion length and orientation is correct. (If tube is equipped with
hose stopper, insert rubber hose into tube until it butts up
against hose stopper.)
