Alcohol resistant fiberglass wing tanks for Kitfox IV

Back when I started flying at a young age it was beat into our heads by instructors to use the correct fuel. And that Avgas was the best you could get in terms of purity. My dad had a Piper Clipper that had a auto gas STC, but he never put anything but Avgas in the tanks. I guess it's just my upbringing. But then again auto gas was lacking the ethanol we have now. I called a hose and fitting vendor for work this week and asked what hose they had that was gas/ethanol proof and they could not supply me with any products.

And yes, I did run a little avgas in my car as a kid. Due to a Cessna AD, it was free for the taking at the FBO I worked for. I broke a piston in my Hot Rod Olds. But it sure did run great for a while.

I have always run ethanol free MoGas in my mid 90's vintage Model 4 and have had no issues. I ran 100LL to and from OSH this year when I would stop for fuel and it's amazing how fast the lead deposits build up on spark plugs.
