Inspection Before Removal

WARNING: This page is about a different car, the 2018 Nissan Titan XD. However, it is still accessible from the selected car via links, so may be relevant.

WARNING:

The fuel system (fuel pump, fuel rail supply line (high-pressure), fuel rail, injectors) contain very high pressure fuel. To avoid the risk of personal injury or fire:
- Do not loosen any fittings while 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.
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 diesel fuel into an approved container and safely dispose of in accordance with local environmental regulations.

Inspect the high-pressure fuel rail supply lines for leaks, cracks, damage, loose connections, chafing, or deterioration. If necessary, replace damaged parts.
NOTE: Make sure the fuel line is not rubbing on any other components.
If the fuel rail supply lines (high pressure) have a visible red/orange corrosion associated with rust after rinsing debris, replace the component.
