Fuel Tank

Removal

Disconnection way for all fuel pipe coupling joints in 
following procedures is shown in the illustration.

1. Release fuel system pressure (

See page 08-10

).

2. Turn off all the electrical equipment and ignition switch.
3. Disconnect the negative battery cable.
4. Open the fuel filler door, rotate the fuel tank cap 

assembly in the direction of arrow as shown in the 
illustration and discharge fuel vapor in fuel tank.

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

 DO NOT damage disconnected fuel system line or connectors. Cover line joints or connectors with 

plastic bags or equivalent, preventing foreign matter from entering.

 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.

5. Disconnect line and wire harness connections on electric fuel pump assembly side.

a. Remove the rear right seat (

See page 46-25

).

b. Using a flat tip screwdriver (1), pry up the electric fuel 

pump assembly protective cap (2).

c. Disconnect the electric fuel pump assembly connector 

(arrow).

d. Disconnect the coupling joint (1) between electric fuel 

pump assembly and inlet pipe I assembly.

e. Disconnect the coupling joint (2) between electric fuel 

pump assembly and inlet and return pipe assembly.

6. Remove the fuel filter assembly (

See page 08-12

).

7. Remove the fuel tank.

a. Loosen the worm clamp (1) and disconnect the 

connection between fuel breather hose and filler tube 
assembly.



(Tightening torque: 3.5 ± 0.5 N·m)

b. Loosen the worm clamp (2) and disconnect the 

connection between fuel filler hose and filler tube 
assembly.

c. Pull out the fuel breather hose from the body 

installation hole.

d. Disconnect the coupling joint (1) between inlet and 

return pipe assembly and inlet pipe II assembly.

e. Move away the fuel vapor pipe III assembly (2) from 

the pipe clamp on fuel tank.

f. Disconnect the coupling joint (arrow) between fuel 

vapor pipe I assembly and fuel vapor pipe of fuel tank.

g. Support the fuel tank with a transmission carrier.

h. Remove 4 fixing bolts (arrow) from fuel tank fixing 

strips and remove the fuel tank fixing strips.



(Tightening torque: 25 ± 3 N·m)

i. Slowly lower the transmission carrier to remove the fuel tank.

8. Remove the fuel pump pressure cap (1), electric fuel 

pump assembly (2) and fuel tank seal ring (3) from fuel 
tank.

9. Remove the fuel level sensor.

a. Remove 5 fixing screws (arrow) from fuel level sensor.



(Tightening torque: 5 ± 1 N·m)

b. Remove the fuel level sensor from fuel tank.

Fuel Tank Accessories Description
1. Fuel Vapor Valve

Function of Fuel Vapor Valve:
When fuel vapor is produced in fuel tank, the vapor will enter charcoal canister through fuel vapor valve (1) 
by fuel vapor pipe (2). When vehicle body bumps or overturns, fuel vapor valve will automatically lock to 
prevent fuel overflow.

2. Fuel Breather Pipe

Function of fuel breather pipe:
When filling fuel tank through fuel filler, fuel vapor will get out of fuel tank through fuel breather pipe (3).
