To remove

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.



1. Reduce the fuel pressure by removing fuse no. 4 (Relay centre in the engine bay) while the engine is running. Turn the ignition key to LOCK once the engine has stopped.

2. Fit the fuse again.

3. Remove the upper engine cover.

4. Remove the fuel pipe from the connection (A).


5. Plug the connection on the pipe.
