Warning
• Fuel vapor is hazardous. It can easily ignite, causing serious injury and damage. Always keep
sparks and flames away from fuel.
• Fuel line spills and leakage are dangerous. Fuel can ignite and cause serious injuries or death and
damage. Fuel can also irritate skin and eyes. To prevent this, always complete the following “Fuel
Line Safety Procedure”.
• A person charged with static electricity could cause a fire or explosion, resulting in death or
serious injury. Before performing work on the fuel system, discharge static electricity by touching
the vehicle body.
Fuel Line Safety Procedure
Note
• Fuel in the fuel system is under high pressure even when the engine is not running.
1. Remove the fuel-filler cap and release the pressure in the fuel tank.
2. Remove the fuel pump relay.
3. Start the engine.
4. After the engine stalls, crank the engine several
times.
5. Turn the ignition switch to the LOCK position.
6. Install the fuel pump relay.

AFTER REPAIR PROCEDURE[L3 WITH TC]
id011439800400
Warning
• Fuel line spills and leakage are dangerous. Fuel can ignite and cause serious injuries or death and
damage. When installing the fuel hose, perform “Fuel Leakage Inspection” described below.
Fuel Leakage Inspection
Warning
• Fuel line spills and leakage are dangerous. Fuel can ignite and cause serious injuries or death and
damage. Always carry out the following procedure with the engine stopped.
• A person charged with static electricity could cause a fire or explosion, resulting in death or
serious injury. Before performing work on the fuel system, discharge static electricity by touching
the vehicle body.
Caution
• Connecting to the wrong check connector terminal may cause a malfunction. Carefully connect
only to the specified terminal.
