Photo 8.1A. The fuel tank vent is an early type.
Photo 8.1B. The fuel tank vent is the last type.
2. The chamber consists of three separate cells connected to each other by holes.
3. If you are filling up a full tank, please remember the following.
4. When the fuel reaches the end of the tank vent tube, the dispenser pump will automatically turn off. In this case, the tank will be 95% full. A little more fuel can be added slowly over the next 30 seconds. After this, you should stop adding fuel, because... otherwise there will be no room for it to expand, and as the temperature rises, some of the fuel will be lost through the vent tube.
5. The ventilation chamber also acts as a housing for the fuel shut-off valve. This valve prevents fuel from leaking out of the tank through the ventilation chamber in the event, for example, of a car overturning during an accident.
6. To remove the ventilation chamber, remove the clamps and disconnect the hoses from it.
7. The hose clamps should be loosened with a screwdriver and then thrown away, because they cannot be reused. New clamps will be required during reassembly.
8. To check the operation of the valve, turn the chamber over, pour a little gasoline into the pipe "A" and check that it does not flow out of the pipe "IN" (see fig. 3.8).

9. Install the camera in reverse order. Check that the hoses are connected correctly and secure them with new clamps.
