Fuel tank

Warning

Changing the fuel tank involves work on the car's fuel system. The following points must therefore be considered in connection with the work:



• Make provision for good ventilation! If approved ventilation for extracting fuel fumes is available then it must be used.

• Use protective gloves! Prolonged contact with fuel may irritate the skin.

• Keep a class BE fire extinguisher close at hand! Watch out for sparks, e.g. in connection with breaking electric circuits, short-circuits, etc.

• Smoking is absolutely forbidden.
