It has been reported by one our dealer, the case of 3 planes in his Country, contaminated by water into the fuel circuit. It is clear that most of our customers buy the fuel directly to a common petrol automotive station. Unluky not all the time the fuel bought there is free of water. It could happen for example that their “tank” could be almost empty in the right moment you are purchasing the fuel for your plane and this could cause that some water that normally is on the bottom of the tank will go finally in your plane.
To avoid this high risk we simply suggest to search locally your “fuel funnel”. This cheap and interesting product is manufactured and visible here : http://www.mrfunnel.com/Mr._Funnel/Home.html
