[huhhhhh]

So I need to remove a black tank out of my 2012 Fuzion 405 Toy Hauler.
I have everything disconnected and it seems that Keystoned glued in the inlet and vent pipe to the top of the tank so it wont drop out.

What is the best way to disconnect the tank from these two pipes. I may be able to get a saws all in there for the inlet pipe but the vent pipe may be out of range.

I've seen 1-1/2 and 3 inch rubber tank grommets that I can put in a new tank to run the inlet and vent pipe back into. I think that's the only chance of getting a new tank back into the rig. Can't think of a way to get the pipes glued back in with no space to work in. They must have glued those pipes in before they put the floors in. Can't see any other way there would have been access to do that.
