Before I screw up-
Can I stick an end of a coat hanger and push from the inlet side to loosen the spring in there?
The plunger thingy is stuck down in there

Probably has a chunk of debris in there, like a piece of o-ring, for instance.

There is nothing preventing the plunger from coming up.
What is behind the plunger?
Is there another O -ring?
Can I stick an end of a coat hanger and push from the inlet side to loosen the spring in there?
Should I take out the old o rings and heat the fitting?

Those parts are all loosey-goosey in there. I suppose the spring might be rusted away. Sure, poke all you want, nothing to really hurt.

Yes you can push the internal brass thing from either side. When it is working properly the internal piece seals the line from leaking. When you plug the two parts together gas can flow through. If you have the right size punch you can drive the entire insides out from the hose side. Once you have it apart you will have an “AHAA” moment! That internal part is actually square. There is a spring a washer and an O ring inside there. The right size O ring are kinda hard to find. I bought some from ebay and they were to big.

don’t be scared get a bigger hammer!

I bought one of those tool back when Frank was making them. If you are going to be doing any work with pressure tanks, that tool is indispensable to have around. It makes an awkward job simple as pie.

Long live American manufacturing!

Just be sure to check that it isn’t leaking before you commit to going out on the water with it. Once those O-rings inside get beat up they don’t generally do the job well anymore. Besides, if they’re old, they’re junk anyway. Hard to beat a $20.00 refurb for those connectors.
