The ventilation system consists of a central pipe (42/2) with an interruption vessel (42/1) at each end.
The interruption vessels prevent fuel escaping along the vent line. The vent line (91) runs from the central pipe to the vent hose (93).
On vehicles fitted with a gasoline engine, the vent hose (93) runs to the activated charcoal canister. As of approx. 7/98 a vent valve is integrated in the vent line to the activated charcoal canister (without (USA)).
