Home  id0114q9802000

Warning

•  Always keep sparks and flames away from fuel. Fuel can be easily ignited which could cause serious injury or death, and damage to equipment

•  Fuel line spills and leakage from the pressurized fuel system are dangerous. Fuel can ignite and cause serious injury or death, and damage to property and facilities. Fuel can also irritate the skin and eyes. To prevent this, always execute the following line safety procedure.

•  A person charged with static electricity could cause a fire or explosion, resulting in death or serious injury. Before servicing the fuel system, make sure to discharge static electricity by touching a vehicle.

Caution

•  If foreign matter enters the fuel passage, it could cause serious damage to the fuel injection related parts. When removing/installing the fuel injection related parts, pay close attention so that foreign matter does not enter the fuel passage.

Note

•  When the engine is stopped, fuel in the fuel system is pressurized.

Fuel Line Safety Procedure

1.  To prevent fuel spatter and leakage of the fuel system, perform the following procedure:

(1)  Remove the fuel-filler cap to decrease the pressure between the supply pump (low pressure side) and the fuel tank.

(2)  Cover the disconnection area of the fuel hose with a cloth and slowly disconnect it.

(3)  Plug the hose after disconnection.

2.  If any servicing between the supply pump and the fuel injector (high pressure side) is performed, perform the following procedure.

Note

•  The pressure between the supply pump and the fuel injector (high pressure side) can be released by loosening one of the injection pipe nuts.

(1)  Cover the injection pipe nut with a cloth when disconnecting the injection pipe.

(2)  Slowly loosen the injection pipe nut until the fuel pressure is released completely to decrease the pressure between supply pump and the fuel injector (high pressure side).
