Cannot stop bulkhead leaking!

[duncangweller]

I believe it is a 1 3/4 hole. When I had the tank set up in my old place there was a minor leak around the bulkhead which stopped after a few days. Since I have moved o can't get the thing to stop leaking.

Also, now that I have tried a gasket on both sides I can't get the bloody nut off the outside.......aaaaaaarrrggggghhhhhh!
