I was wondering if I could replace the burst disk things in this with the brass kind that you twist in with a wrench. The kind on this is just a disk held in by a hollow grub screw. If y'all know what pressure I should replace the two with(and if I can), please lmk. It's a 68/4500 tank.

Also, when I got the tank, it had a macroline fitting in the right side. There are holes on the bottom and left also, but I don't know if it's possible to put hose there or not. The left hole says "Outlet/Gauge", and the bottom one doesn't say anything(it's the one with the burst disk). Are all of these interchangable?

Finally, this tank needs to be rehydro'd in june of 06 I believe. It's a 3 year tank. If I sent it in to be tested, will it become a 5 year tank automatically? Or will it be a 3 year forever?

Please only tell me answers to these if you know for sure, I don't want to blow this thing up or w/e.....

Thanks.
