I cut open the fuel filter I had on my qjet, which was only a month or two old.... inside it was some light gray powder. (The filter had dried out)....

Any idea what it might be? I dont really want to drop the tank to look into it, but I guess I might have to.

 

If it's not causing any fueling issues, I wouldn't worry about it. Just change the filter more often.

 

Does it look like this?

 

I guess so... like light gray talcum powder. And not as much as in your photo.

 

It was a brownish color. Our tank was rusting out. We replaced it.

I would drive it for short time and check the filter again.
