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.
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 the skin.
- 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.
Fuel can be returned at highly elevated temperatures. Wear safety glasses and protective gloves and clothing when performing this test. Avoid any contact with returned fuel.
To avoid the risk of injury to eyes and skin, when using caustic solutions, solvents, acids, or alkaline materials follow the manufacturer's recommendations for use and wear appropriate eye protection and protective clothing. Some of these materials are also 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. Avoid spilling onto a hot exhaust manifold which can cause a fire.
When using high-pressure water or steam cleaning equipment, to avoid the risk of personal injury from flying debris and hot steam:
- Wear appropriate eye protection and protective clothing including gloves and a face shield.

CAUTION: To avoid possible engine and system damage or performance issues:

Brush away all dirt and debris from the area prior to opening any fuel, air intake, exhaust, cooling, aftertreatment or other engine system.
To avoid contamination, any open engine system ports must be closed immediately with clean care caps or an appropriate covering.
Do not allow any debris to fall into the engine.
Do not allow any chemical cleaners to enter the engine or any open systems during the cleaning process.

Remove intake manifold assembly. Refer to Removal and Installation .
Disconnect the two-button quick-disconnect connector from the high-pressure fuel pump inlet and remove the fuel supply line (1).

NOTE:
- Mark the routing of the fuel supply line to be sure that it is installed in the correct location during assembly.
- Do not bend, pry, or kink the fuel supply line during removal.
- When removing the fuel supply line, cap all fuel openings with Tool.
