sending unit stuck in gas tank

Help please. I've done this before and don't know why I'm having trouble this time. I am trying to replace the sending unit in my 1965 GTO fuel tank. The tank is out and empty. I have removed the inner lock ring. I've sprayed PB blaster around the sending unit. I've pulled, pushed, hammered (lightly), twisted. It will not come out. What am I missing? I don't remember this being so difficult before. This is the original unit I believe. Did they glue them in at the factory in 65? Help please?

Are you sure you are trying to remove only the very center of the unit where the fuel hose is connected?
As I recall, the only thing under the center portion is the rubber gasket.
I suppose someone could have had the unit out and installed them with a adhesive of some kind.

Thanks for the reply.
I believe so. I will get back out to the barn this afternoon to check again and maybe take a picture too.

It came out fairly easily this afternoon. I think the PB blaster finally did its work. Thanks for the replies.

It was actually still flexible and I did not find any evidence of glue or other sealant that was holding it in. Just many years of gunk I guess. I expected it would have a brass float so maybe it's not original. I don't know.
