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.
