pin hole leak speedster fuel tank

[HighWing]

For what it's worth. On one of the Idaho trips - as I recall about 2004 - I noticed about a half dozen small "pimple" like bubbles in the Aerothane on top of the wing just inboard of the fuel filler neck. Uncertain as to their cause, I finally took a razor blade and cut one off. It was filled with fuel. Apparently I had several pin point leaks on the top of the tank. The timing was consistent with California outlawing the MTBE additive and substituting Ethanol. Cause and effect - pretty suspicious. I re-sloshed with the oft maligned Kreem - after removing the factory Kreem with Acetone. For the next three years using California's 10% ethanol reformulated fuel, except on cross country trips, I had no problems with leak issues. The airplane was destroyed in our not so perfect emergency landing near our home ten minutes into our flight to the 2007 factory Fly-in - explanation for the short only three year history.

Pics of the wing support I made to enable wing removal and sloshing with minimal effort. The attachment of the wing tip to the support was a fully mobile gimbal for unlimited movement and the inboard support folded out of the way for manipulation of the wing.

Great idea for the wing removal for sloshing. Thanks for the input
