Re: New wing tanks
James this is not a definitive answer, just a sharing of experience. My Skystar S5 is about the same vintage as yours, first flying in 2007. It now has nearly 500 hours, 90% of which has been on 95 or 98 octane Mogas. Much of that had 5% ethanol. The remaining hours were on 100 LL avgas, when I could not obtain mogas. I am in Europe and we have very good quality fuel delivered to our airfield. Only rarely, on trips, have I used fuel from a local garage.Originally Posted by JamesD
After reading of issues with earlier model Kitfox fuel tanks I've decided to do an annual check on the tanks - which were treated with Kreem as part of the build process. At the last inspection we drained them completely, including removing the fuel drains. No dirt or contamination was found. We then used torches to visually check the security of the Kreem. It is in good condition except for some cracks where the baffles join the skin - that right angle join - a known problem area on early Kitfoxes. While a little concerned about the cracks we decided that this was not yet causing any issues e.g. no flaking of the Kreem or leaking. We also decided to continue this annual inspection.
In your case I would proceed but keep a close eye on the security of the Kreem at the baffle joints and, as far as possible, avoid ethanol, but keep in mind that fuel without ethanol might be difficult to obtain in the future.
