By rubber seal do you mean a gasket? If so, I have that on the inside of the tank. I also used Teflon tape on all my threads to ensure a tighter fit. Maybe I over tightened and am causing the gasket to not sit properly anymore? Now come to think of it, when i removed the bottom bulkheads he didn't have a gasket, just a think round ring that looked translucent.

if there leaking through the threads wrap a little Teflon tape around them that screw them together may help
