I may have solved the problem. Apparently the connection to a slight air suction from the intake to the " can " , with the two fuel pipes ,is to prevent any fuel vapour entering the engine bay from the regulater, I think ?. Anyhow it has no effect on engine preformance and may not be fitted to the meriods of 110 engine types. Even if it was defective I would never know unless the car caught fire from petrol fumes. The unit is there to prevent this unlightly event. Typical Mercedes precaution. ......... Sean
