Removal
Disconnection way for all fuel pipe coupling joints in
following procedures is shown in the illustration.
1. Release fuel system pressure (
).
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.

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).
