Warning

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

• 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.


Important

Be particulary observant regardning cleanliness when working on the fuel system. Loss of function may occur due to very small particles.

It is also important to replace the old plastic screw with a new plastic one. In the event of a possible accident the plastic screw should give way in order to avoid damage to the filler pipe, which is also made of plastic.
