WARNING:
- Diesel fuel and diesel fuel vapor is flammable. To avoid risk of fire or burns, never smoke or allow sparks or flames (such as pilot lights, electrical switches, or welding equipment) in the work area. Never allow diesel fuel to spill onto a hot exhaust manifold which can cause a fire.
- To avoid the risk of personal injury or fire, drain the diesel fuel into an approved container and safely dispose of in accordance with local environment regulations.
- the fuel system (fuel pump, high-pressure fuel lines, fuel rail, injectors) contain very high-pressure fuel. To avoid the risk of personal injury or fire;
- Do not loosen any fittings while the engine is running.
- wait at least 10 minutes after shutting down the engine before loosening any fittings in the high-pressure fuel system to allow pressure to decrease to a lower level.
- Wear appropriate eye protection and protective equipment as high-pressure fuel spray can penetrate skin.
- Never smoke or allow sparks or flames (such as pilot lights, electrical switches, or welding equipment) in the work area. Do not allow diesel fuel to spill onto a hot exhaust manifold which can cause a fire.
- Inspect the high-pressure fuel rail to rail supply lines for leaks, cracks, damage, loose connection, chafing, or deterioration. if necessary, replace damaged parts. If the high pressure fuel rail to fuel rail supply line has visible red/orange corrosion associated with rust after rinsing debris. replace the component.NOTE: Make sure the fuel line is not rubbing on any other components.
