Fuel pressure regulator

Warning

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

• Work only in a well-ventilated area! If approved equipment for the extraction of fuel vapour is available then make sure it is used.

• Wear protective gloves! Prolonged contact with fuel can cause skin irritation.

• Keep a class BE fire extinguisher close by! Be mindful of the danger of sparks caused by short circuits and when connecting and disconnecting leads in electrical circuits.

• Smoking is strictly forbidden.

• Wear protective goggles.
