Abstract
Fuel vapors leaving the fuel tank of a motor vehicle are recovered with a filter cartridge inserted between the tank and the intake manifold of the engine. An atmospheric connection duct of the cartridge can be selectively connected to the intake partial vacuum with a pneumatic distributor. The leaktightness of the device is thereby tested.
