Quick update. Just spent 30 minutes working on the leaking bag and it looks like it's not leaking at all. I filled it up with air and sprayed it down with soap and water and saw no leaks. But looks like it may have been leaking from the PTC fitting that the air line connects too. So that would need to be replaced. That's the only place I would think it would leak. Now that I think about it, I was driving through a construction zone and something may have it the line and yanked on it a little causing the leak.
