I had mine off a couple of weeks ago doing my Condition Inspection. I have to tug a bit but it should come off ok. Maybe put a bit of penetrating oil on it.
I like Gordon’s suggestion too. A Phillips head screw will center the point of the puller.
I have found a lot of those type of things have a drop of loctite put on at assembly. I have to remove the valve awhile ago and just a little heat from a blow dryer made a big difference
