Warning

Removal of the fuel filter involves partial dismantling of the car's fuel system. The following points must therefore be observed in connection with this work:
•	Make sure a class BE fire extinguisher is close to hand! Consider the risk of sparking, e.g. when breaking circuits, short-circuits etc.
•	Absolutely No Smoking!
•	Ensure that there is a good exchange of air. If approved ventilation for the extraction of fuel fumes is available, this should be used.
•	Wear protective gloves! Prolonged exposure of the hands to fuel can cause irritation to the skin.
•	Wear protective goggles.
