Warning

• Fuel vapor is hazardous. It can very easily ignite, causing serious injury and damage. Always keep sparks and flames away from fuel.

• Highly pressurized fuel may spray out if the fuel line is cut. Due to the following dangers occurring with a fuel spray, always complete the “Fuel Line Safety Procedure” to prevent the fuel from spraying.

― Fuel may cause irritation if it comes in contact with skin and eyes.

― If fuel ignites and causes a fire, it may lead to serious injury or death, and damage to property and facilities.

• 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

• Touching the end of the fuel injector by hand or pressing it to an object may cause a malfunction. Be very careful when handling the end of the fuel injector.

• When the fuel distributor is removed, air tightness of the fuel injector will be lost. Always replace the stopper ring, O-ring, back-up ring, spacer, and teflon seal of the fuel injector with new ones.

• Do not remove the fuel pressure sensor from the fuel distributor.
