I should have tried this test while I was out there as I'd heard it before, but simply forgot. I'll try to get out there sometime this week and check it out. I didn't think alcohol/water would cause a catastrophic leak either, but was willing to consider it due to lack of any other ideas. But I think Bob is on to something. Todd First step is to determine if you have alcohol. Aside from corn producing states, alcohol as an oxygenator is pretty much limited to large metro areas that aren't making their EPA clean air numbers. You can easily test your source: Get a largish "test tube" and mark it off in 11 graduations. Fill it up to level 10 with the Mogas you want to sample Top it off with one unit of water Shake it vigorously for a longer time than you really feel is necessary. If you now have 9 - 9.5 units of gas and 2 - 1.5 units of water, you have alcohol. I do not believe your problem is alcohol related since it slowly corrodes tanks that are not properly protected - it does NOT dissolve them catastrophically. Hope this helps ...

Fill=20 it up to level 10 with the Mogas you want to sample

Shake it vigorously for a longer time than you really feel = is=20 necessary.
If you now have 9 - 9.5 units of gas and 2 - 1.5 units of = water,=20 you
