with my Mrod in pieces I should be installing it soon. I'll report back. I was attracted to the "no hole needed" in tube aspect so as to keep the gauge. From a few comments I have read, this may be not such a good thing as the reg may pack with air over time and become useless. I don't no much about regs but I figure, I'll install it and see what happens. If it fails over time, maybe I'll give the other available one a try.
