Huma Reg Leak. Need advice

Hey guys,

I have a Huma Reg I purchase from AOA for my P-Rod .22. I installed it per the instructions excluding the pressure gauge. However, it leaks from the pressure gauge hole. I then installed it with the pressure gauge and the gauge only read reservoir pressure and not reg pressure. I had AOA send me another reg and still the same problems. Any ideas? I think the it's something to do with my air cylinder. Any help would be much appreciated.



Thanks guys!
