So I have a relatively new Kral Puncher Jumbo that I wanted to put a Huma regulator on. I received the regulator yesterday and installed it on the gun per the instructions. I hooked the gun up to my also new compressor and filled it up. As soon as I stopped the compressor the Huma gauge on the regulator not the gun immediately began losing pressure? I figured something was obviously leaking so I grabbed some soapy water mix and sprayed around all of the connections. I could not find a single leak anywhere? I tried this several times de-gassing the gun and refilling it only to have the reg pressure gauge lose pressure immediately after stopping the compressor at 200 BAR? I thought that maybe the gauge was faulty so today I installed a brand new Sekhmet digital gauge on the regulator. I filled the gun and once again the same behavior with the digital gauge. It immediately lost pressure and settled at about 152 BAR without losing any additional pressure? I am at a complete loss as to what is going on here? I can't find any leaks anywhere and believe me I tried a ton. So where is the air going or is there some other strangeness going on that I am not aware of being that this is my first PCP gun? I sent an email to Huma but it is the weekend so I assume nobody is going to get back to me until tomorrow at the earliest. I recorded a video today of what it is doing and uploaded it to my Dropbox the link is below.
