He's right about that...once I turn on my left "aux" wing tank, it'll start a siphon that doesn't quit until both tank levels are equalized, which is kind of convenient in my case. Wicks sells a Facet pump called the 40171 that has positive shutofff when the power is disonnected. I just bought one last week for the 8 gallon outboard wing tank I'm building for my KR. In that case I want better control over that particular tank. My It's at http://www.wicksaircraft.com/catalog/product_detail.php/pid=9401~subid=11800/index.html . In other news, I can now report that vinylester resin sucks even more than I remembered. I built my first tanks in my cool basement, but when you use that stuff in a 98 degree hangar, the pot life is measured in terms of a very few minutes. Normal layup procedures have to go out the window, and new super-streamlined ones implemented. I'm sure that's another reason vinylester is a favorite of manufacturers...
