capillary tube

As a part of my dissimilar metals corrosion education I have managed to turn my temperature sending unit on my 1937 120 into a two part piece of junk. I have seen where to send the remains for resurrection but have not yet been able to liberate the bulb that is still stuck in the head.
I've been soaking it in Mouse Milk, PB Blaster, ATF and acetone nothing is working.
Any suggestions? Thank you in advance.
