It consists of a 450 mm long tube, 2 mm thick fiber reinforced nylon and a valve
This system prevents the effect of vacuum in the tank during long journeys, thus ensuring an optimal fuel supply from the tank to the carburettor.
The valve allows fresh air to enter the tank, depending on the gasoline level cutoff, and prevents ev. Motorcycle tip over (e.g. fall) a leak of fuel from the filler cap vent hose..
