There was debris and shavings all around the reg and bonnet, i tried to clean it the best i could. So now with the burst disk blown, do you think i should just replace the disk, or can leftover shavings cause the disks to keep blowing out? If thats the case i will just buy a whole new reg for the tank. So...replace disk or whole reg?
Can you post a pic of the ring gouged into your reg body? That could likely be the issue causing the leak, not necessarily your burst disk. Has this been a constant issue since your bonnet incident or a recent development? If this is a new problem then I would highly suggest you clean your reg and see if that works.
To clean your reg, safely degas your air system and remove the grub screws. Once you remove the screws take your bonnet. Lift your bonnet off slowly and remove all your internals, paying attention to what order everything is in (the shims do not matter though). Clean the inside of the reg body and bonnet out with q-tips or something similar so you are able to reach all the tight areas. Visually inspect the piston oring and the oring below the pin valve opening in the bonnet for nicks and wear and replace them if they are damaged. Wipe everything down with a clean cloth or towel and then relube with some form of paintball grease (Dow33/Sleek/SLick/PE Grease etc) making sure to NEVER USE OIL as your reg could/would explode upon trying to fill it. Once you have relubed everything, put the internals back in the system as they were, tighten the bonnet and tighten the grub screws.
Hope this helps you out man!

Is there any air in your tank? If not, then you are most likely hearing the shuttle valve within the fill nipple. It is a pin with an oring on it that creates the seal when you are done filling your tank that moves semi-freely with no pressure in the tank. If you do have air in the system, I would refer to my advice above on cleaning the reg, but also paying careful attention to what internals you have in your reg and comparing them to the schematic of a new regulator to make sure A) your internals are all there and that B) they are in the proper order.
Hope this helps!
