Wow thanks for all the responses.
Its a 26 gallon tank, 5.5peak hp 1.7 maint with 150psi max. The hose is 9mm 3/8'' hooked up to a husky 275maxpsi impac gun. I hammered it for a good while with no success.
I believe I actually tried that breaker method, I just cowered out after hearing some undesireable noises. I felt like I was going to break something if I racked it foreward much harder. Perhaps I should have just used my man hands and gone through with it. It's all back together now so I will have to try it for another day.
