This is my 1st time opening my pool and had everything hooked up, turned on the pump and in a matter of seconds the pressure gauge (previous owner left it in over winter) blew off leaving the brass threads in with the plastic threads of the sand filter. I'm just curious if anything has had this problem before and how'd you get the threads cleamed up without messing them up. Any and all information would be greatly appreciated.

Welcome to TFP!!
If you are saying that the gauge separated from the brass threads that are normally attached to the gauge, and that the threaded portion that is supposed to be on the gauge is still in the filter head, the you need an appropriately sized EZ-out.

Is that the gauge that blew out? I assumed it was a new one. I agree with @JamesW, looks like the threads in the valve are toast.
I am concerned the threads in the filter housing may have been deformed. And while you can clean them up when you put a new gauge in please check if the threads are loose or the same thing can happen. Somehow you overpressured the system or something blocked.
The gauge is a brand new gauge. What happened is the old gauge (not pictured) blew off and it was a hollow thread body attached the gauge. The guy at the local pool store said the gauge looked very old. If you see the picture of where the new gauge is suppose to go, it won't go in. The remnants of the old hollow bolted gauge (not sure how else to word it) are stuck in the threads of the filter and I cannot thread anything else into it. Hopefully that makes sense for more detail of a description.

From the videos I was watching those are used from a broken bolt. In the picture I'm attaching, there is no bolt. Just brass fragments from the old pressure gauge thread stuck in the plastic threads of the filter system.
If I drill them out, then the plastic threads on the filter will be compromised and I'm afraid the new gauge won't screw in at all. If that's the case, I would have to buy a completely new lid for the filter.

I agree. The filter threads look like they should accept a gauge. It doesn't look like a part of a gauge is stuck in the filter threads. Here's a screenshot of similar Hayward filter...
Make sure you have the right size gauge. Try cleaning up the threads. There may be sealant or old tape stuck in threads.
@1poolman1...what do you think?

Is there a certain way to clean up the threads you would recommend?

I stand corrected. It certainly looks like that fitting split in half.

Doesn't it make sense to use an ez-out to remove the brass from the old gauge?Drill America 1/4 in. -18 Carbon Steel NPT Pipe Tap DWTPT1/4 - The Home Depot

Are you suggesting that the tap will push the broken portion into and through the valve?
There doesn't appear to be anything in the threads but a little Teflon tape or sealant residue. The tap will remove that. If turned slowly and removed after every turn or so whatever might be in the threads will fill the taps flutes and can be removed from the tap. Needs to be inserted straight so as to not cut new threads. Won't push anything in. Just go slow.
You have to remember that the filter is some form of fiberglass - not metal. The threaded portion can be deformed easily with tools that are designed for metal threads. If you want to remove the remains of the brass from the threaded port, I would use a pick or similar object to work those brass pieces out. Then I would use a plastic plug to test the threads. The is a pressure vessel, so something caused the threads to give out - the OP has not said but hopefully no one was injured. I would exercise a lot of caution.

Gauge is in the plastic MPV. A tap slowly used will clean and chase the threads.

Right, so you are saying it will push it through? Or are you saying it will cut it up? Thanks for your expertise!
