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.
I bought automotive 5/8? heater hose and a molded elbow to replace mine. The specs were something like 350F and 50 psi on them, and I found them online at an auto racing shop.
