Venting the fuel system
Venting the fuel system using a suc-
tion tool
Tools
Note:
Scania recommends venting the fuel system us-
ing suction tools rather than with a hand pump.
This is a quicker and simpler method, which en-
sures a complete venting.
Environment
Use a suitable container. The fuel collected must
be disposed of as specified in national and inter-
national laws and regulations.
1. Attach a clear plastic hose to the bleed nipple
on the fuel manifold. Start by wiping off the
bleed nipple. Place the end of the plastic hose
in a container that holds at least 3 litres
(1 US gallon).
2. Connect the suction tool.
3. Connect compressed air to the suction tool.
Turn the rotary control to create a vacuum.
4. Open the bleed nipple.
5. Hold the suction tool straight and suction out
the fuel. Once the fuel coming out of the
plastic hose is free of air bubbles, then vent-
ing is complete.
6. Close the bleed nipple. Remove the plastic
hose and suction tool.
7. Start the engine and check that there are no
leaks.
