Hey Sandy,
My elbow unscrewed pretty easily also. I let a single drop of liquid wrench sit for about 20 mins. Probably didn't even need it as I later noticed it had some Teflon tape on it. I get the mixed metals corrosion issue, but should I change the brass fitting for aluminum or stick w/ the Teflon tape barrier?

Any thoughts on how to assess the pickup tube itself? I have to imagine there is one in place, or my motor wouldn't have been able to suck down 20 gallons or so...Is it possible that the tube was an integral part (welded in place to the fitting nut) of the tank?

Also, are there any tried and true ways to seal the tank cover other than the 4 corner screws; weatherstripping, silicone, what? I'd almost like to form a gasket around it lip of the cover and just just the screws clamp it down...
