3. Fuel Tank Cushion

Pay attention to installation positions of fuel tank
cushions (arrow). Incorrect installation will damage the
fuel tank or fuel pipe due to friction between fuel tank and
body.

Installation

1. Install the fuel level sensor.

a. Install the fuel level sensor into the fuel tank.

b. Align mark (1) on the fuel level sensor and mark (2) on

the fuel tank.

c. Install 5 fixing bolts (arrow) to the fuel level sensor.



(Tightening torque: 13 ± 2 N·m)

2. Other installation procedures are in the reverse order of removal.

CAUTION

 DO NOT break the float when installing the fuel level sensor.

RT21080251

CAUTION

 Fuel lines and ventilation pipes must be reinstalled to the original positions on fuel tank. Otherwise the

friction caused by body vibration will damage fuel lines and lead to fuel leakage.

 Before connecting hose, check if there is any damage or foreign matter on hose or joint.
 During installation, push in fuel pipe connector until a click sound is heard, then check that fuel pipe joint

clip is on the collar of fuel pipe joint. After installing the pipe joint clip, check that fuel pipe joint cannot be
pulled out. Be careful not to damage the joint. If the clip is damaged, replace it.

 Turn ignition switch ON (without starting engine) to apply fuel pressure to fuel supply system, and then

check connections for leakage.

Fuel Rail Injector Assembly

Removal

1. Release fuel pressure in fuel supply system (

See page 08-10

2. Turn off all the electrical equipment and ignition switch.
3. Disconnect the negative battery cable.
4. Remove the engine trim cover assembly (

See page 10-10

5. Remove the fuel rail injector assembly.

a. Disconnect the connectors (arrow) of 4 injectors

separately.

b. Move away the engine wire harness clips from fuel rail.

WARNING

 Before operating fuel supply system, please touch vehicle body to discharge static electricity; failure to

do so will cause a fire, even result in an explosion.

 When operating fuel supply system, work area should be in good ventilation and keep fire sources or

open flames away from the work area, in which the fire extinguisher should be equipped.

 After performing procedures for fuel system pressure release, there still remains some pressure in fuel

line. When disconnecting fuel line, cover the joint with a piece of cloth or equivalent to prevent fuel from
spraying out.

 If fuel leakage occurs when operating fuel supply system, please handle the leaked fuel in time.

CAUTION

 Be sure to wear necessary safety equipment when repairing to prevent accidents.
 Try to prevent body paint surface from being scratched during removal and installation.
 DO NOT damage the disconnected fuel system line or connectors. Cover line joints or connectors with

plastic bags or equivalent, preventing foreign matter from entering.

 Injector is a part of high accuracy, featuring good anti-clogging, anti-pollution and atomization, so be

careful not to damage the injector during removal of fuel rail.

c. Disconnect the coupling joint (1) between delivery

pipe and fuel rail.

d. Loosen and remove 2 fixing bolts (arrow) from fuel

rail.



(Tightening torque: 8 + 3 N·m)

e. Remove the fuel rail and fuel rail injectors.

6. Remove the injector clamps and remove the injectors

(arrow) from fuel rail.

Inspection

1. Disconnect the injector connectors.
2. Measure resistance between 2 terminals (injector side) of

injector with a digital multimeter.

Installation

Installation is in the reverse order of removal.
