WARNING:
When replacing fuel line parts, be sure to observe the following:
IDisplay a ªCAUTION:INFLAMMABLEº sign in workshop.
IBe sure to furnish workshop with a CO
2fire extinguisher service.
IDo not smoke while servicing fuel system. Keep open flames and sparks away from work area.
IBe sure to disconnect battery ground cable before conducting operations.
IPour drained fuel into an explosion-proof container, then ensure container lid is installed securely.
CAUTION:
IFor ECM models, release fuel pressure from fuel line. Refer to EC section (ªFuel Pressure Releaseº,
ªBASIC SERVICE PROCEDUREº).
IDo not disconnect any fuel line unless absolutely necessary.
IPlug hose and pipe openings to prevent entry of dust or dirt.
IAlways replace top lid seal and hose clamps with new ones.
IDo not kink or twist hoses and tubes during installation.
IDo not tighten hose clamps excessively because this could cause damage to the hose.
IEnsure fuel check valve is installed in the correct orientation.
IRefer to EC section (ªFUEL CHECK VALVEº, ªEVAPORATIVE EMISSION SYSTEMº).
IAfter installation, run engine and check for fuel leaks at connections.

REMOVAL
Petrol engine
1. Release fuel pressure from fuel line.
Refer to EC section (ªFuel Pressure Releaseº, ªBASIC SER-
VICE PROCEDUREº).
2. Remove inspection hole cover located under the luggage com-
partment carpet.
3. Remove fuel filler lid.
4. Disconnect fuel outlet, return tube and connectors.
CAUTION:
Mark the fuel tubes to ensure correct position during installa-
tion.
5. Remove the fuel gauge assembly and disconnect tubes and
connector.

6. Remove fuel pump with fuel tank chamber assy as follows:
a. Push the locking clip upwards and slide the pump chamber
assy towards the rear of the vehicle.
b. Lift the pump chamber assy from the bracket.
c. Carefully remove the pump chamber assy and top plate from
the tank.
7. Take off the fuel pump chamber lid by opening out the 4 clips.
Remove the fuel pump from the fuel pump chamber.
INSTALLATION
Installation is reverse procedure of removal.
CAUTION:
IAlways use a new top plate seal.
ITighten to specified torque.
Diesel engine
1. Remove inspection hole cover located under the luggage com-
partment carpet.
2. Disconnect fuel feed and return tubes and connector.
3. Remove the screws by which the fuel gauge is mounted to the
fuel tank.

Precautions for Multiport Fuel Injection System
or Engine Control System
1. Before connecting or disconnecting any harness connector for
the multiport fuel injection system or ECM (Engine Control
Module):
Turn ignition switch to ªOFFº position.
Disconnect negative battery terminal.
Otherwise, there may be damage to ECM.
2. Before disconnecting pressurized fuel line from fuel pump to
injectors, be sure to release fuel pressure to eliminate danger.
3. Be careful not to jar components such as control unit and air
flow meter.
Precautions for Catalyst
If a large amount of unburned fuel enters the converter, the con-
verter temperature will rise to excessively high values. To prevent
this, follow the procedure below:
1. Use unleaded gasoline only. Leaded gasoline will seriously
damage the catalytic converter.
2. When checking for ignition spark or measuring engine
compression, perform tests quickly and only when necessary.
3. Do not run engine when the fuel tank level is low, as a result
the engine may misfire causing damage to the converter.
4. Do not place the vehicle on inflammable material. Keep inflam-
mable material off the exhaust pipe.
Precautions for Turbocharger
The turbocharger turbine revolves at extremely high speeds and
becomes very hot. Therefore, it is essential to maintain a clean
supply of oil flowing through the turbocharger and to follow all
required maintenance instructions and operating procedures.
For proper operation of the system, follow the procedure below:
1. Always use the recommended oil. Follow the instructions for
proper time to change the oil and proper oil level.
2. Avoid accelerating engine to a high rpm immediately after start-
ing.
3. If engine had been operating at high rpm for an extended period
of time, let it idle for a few minutes prior to shutting it off.
