My SWMBO accidentally knocked over my CO2 tank with the regulator attached tonight and it busted the high pressure gauge. I have this Taprite regulator. The high pressure gauge took the hit and it dented the end of the gauge, crumpled the panel that shows the pressure a bit and the needle is stuck. I hooked it up and the regulator appears to work fine, no leaks that I can detect so far. Question is, do I need to replace this thing or will I be ok (other than the fact that I can't get a reading from that gauge)? Both low pressure regulators appear to be fine and after hooking up to a couple of kegs and bleeding pressure they both returned to the set pressure and stayed. Hoping I can get by without having to buy anything else, thoughts?
