Air compressor problem.

[donthekawguy]

I got my new to me compressor today (Champion 80 gallon). While we were unloading it, the air fitting holding the inline driers broke off. The tube that screws into the fitting on the side of the tank is broken off inside the fitting with no threads sticking out so I can't grab on to get it out. The big fitting is also stuck in the tank and I have already broken my adapter trying to get it out. lol I don't think I will be able to get it out with a punch because it's been in there so long. I have spray it with penetrating oil so that might help. Any tool that I can get that will reach in there and grab the pipe to turn it?
