Warning

The work involved in removing the fuel pipe requires working with the vehicle's fuel system. The following points should therefore be heeded in conjunction with these measures:

• Have a class BE fire extinguisher on hand! Be aware of the risk of sparks, i.e. in connection with electric circuits, short-circuiting, etc.

• Absolutely No Smoking!

• Ensure good ventilation! If there is approved ventilation for evacuating fuel fumes then this must be used.

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

• Wear protective goggles.


50. Release any pressure in the fuel system by carefully pressing the service valve needle. Collect any fuel spill. Detach both fuel lines from the fuel rail while gripping the lower nut. Plug the fuel lines. Use 82 92 948 Plugs, A/C system, kit .
