I was figuring to use compound buildup, as craigrr shows in the original post in this thread.
To add stability, one could also put threaded bolts through the tank, with a nut on either side of the tank (inside would get a lock-washer). This would keep the bolts from pulling out, and would give much more support to the goop. There is easy access to the inside of the tank, near the opening, so it should be a cinch.
For that matter, you could use 2" bolts, assemble as in previous paragraph, then put a hose clamp around the bolts, holding them tight to the connector. Smear all with goop, and it seems like it should be rock-solid.
