Fuel shut off during filling of the fuel tank

VEHICLES CONCERNED

Saab 9-3 SS, SC, CV with diesel engines from MY -03.

BACKGROUND

In some cars, it is hard to fill the fuel tank due to restriction in the fuel tank ventilation hose.

SYMPTOM DESCRIPTION

Too early shut-off or spit back during fuel filling.

ACTION

Check and clean the fuel ventilation hose in the fuel tank as follows:


1. Lower the fuel tank for access.

2. Uncover the rubber protection (1) above the ventilation hose (2) from ventilation blue cover and clean the inside of the pipe.


3. Make a simple tool as shown below. Bend a steel wire 500 mm long (20 inches) in the middle. Locate a piece of cloth (cotton) in the loop (proper size to fit inside the hose). Twist the wires.


4. Insert and move/turn the "tool" through the ventilation hose in to the blue cover until the hose is clean. Use a dry cloth. Do NOT use any liquids, cleaning agents or solvents when cleaning the tube.


5. Locate the rubber cover to correct position above the ventilation hose.
