Fuel Filler Pipe
WARNING: This page is about a different car, the 2003 Saab 9-3. However, it is still accessible from the selected car via links, so may be relevant.
Fuel is filled into the filler pipe and flows through a non-return valve into the tank.
At the top of the filler pipe there is an insert that ensures a good alignment of the fuel nozzle during refueling.
IMPORTANT:
The tank must never be drained by suction through the filler pipe as this will damage the non-return valve!
