Checking fuel pressure

Warning

Removal of the fuel pressure regulator is a procedure involving the car's fuel system. It is therefore necessary to observe the following precautions in conjunction with the procedure:

Ensure good ventilation! If there is approved ventilation for extraction of fuel fumes then this must be used.

Wear protective gloves! Prolonged exposure of the hands to fuel can cause irritation of the skin.

Have a fire extinguisher class BE at hand! Be aware of the risk for sparks, i.e. in connection with circuit breaking, short-circuiting, etc.

Absolutely no smoking!

Use protective goggles.
