Installed the rear baffle and spar mounting " Z " brackets on both the left and right fuel tank. Tanks are complete except for the drain plug and fuel supply screen/fitting. I plan to test the tanks in about two weeks. Vans recommends waiting at least one week to let the tank seal cure... but with the cool/damp weather, I don't want to take any chances. I will wait at least two weeks before I check for leaks.
