Bleeding of fuel lines

Bleeding of fuel lines

Warning

Removing the fuel line involves work on the car's fuel system. The following points must therefore be observed when taking any action:

• 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, e.g. in connection with circuit breaking, short-circuiting, etc.

• Absolutely No Smoking!

• Wear protective glasses.



To speed up bleeding the fuel system when air enters, for example while changing a filter or when the fuel lines on the inlet side have been removed, use the method below.


1. Connect 30 31 069 Nipple, bleeding equipment , to 88 19 096 Bleeding equipment or equivalent and start the suction equipment.


2. Remove the end cap and connect the nipple to the service outlet on the fuel pump feed line.

3. Suck until a constant flow of fuel is seen in the suction line to the brake-bleeding tool.

4. Remove the bleed nipple from the service outlet while it is still sucking (to avoid fuel spillage and air entering the system.)

5. Put on the end cap for the service outlet.
