Injection pipe/Fuel rail, V6

To remove

Warning

Removal of the fuel rail involves partial dismantling of the car's fuel system. The following points must therefore be observed in connection with this work:

• Make sure a class BE fire extinguisher is close to hand! Consider the risk of sparking, e.g. when breaking circuits, short-circuits etc.

• Absolutely No Smoking!

• Ensure that there is a good exchange of air. If approved ventilation for the extraction of fuel fumes is available, this should be used.

• Wear protective gloves! Prolonged exposure of the hands to fuel can cause irritation to the skin.

• Wear protective goggles.


Important

Be particulary observant regardning cleanliness when working on the fuel system. Loss of function may occur due to very small particles. Prevent dirt and grime from entering the fuel system by cleaning the connections and plugging pipes and lines during disassembly. Use 82 92 948 Plugs, A/C system assembly. Keep components free from contaminants during storage.
