Probably the best way is to take old hoses off and then install new hoses in their place?
One of the cylinder hoses is a molded elbow and you will need to purchase from Rotax part distributor ? Lockwood/LEAF. The remaining cylinder hoses are cut from straight length that can be purchased from local auto part store. I would buy high-grade silicone hose.
