Safety Precautions When Working On Fuel Supply System

The fuel lines are under pressure.

Fuel poses a risk of injury to the eyes and skin.

Wear protective eyewear and protective clothing to avoid injury and contact with the skin. Place a cleaning cloth around the connection point before loosening hose connections. Carefully open the connection points to release the pressure.

There is a risk of injury because the fuel is under very high pressure.

• The fuel injection system is separated into a high-pressure section (maximum approximately 120 bar (1740 psi)) and a low-pressure section (4 to 7 bar (58 to 101.5 psi)).
• Before opening high pressure system, fuel pressure must be reduced to a residual pressure of approximately 6 bar (87 psi). Procedure. Refer to HIGH FUEL PRESSURE, REDUCING .
