I have a Cricket original, I have tried to remove the manometer I have the tool to remove it but cannot hang on to the threaded area while turning the tool to remove the gauge, it is stuck. I removed the housing that the gauge is in and those are the threads I am holding. I have replaced the O-rings and am still getting some air out of the barrel. Could that air coming out of the barrel be from another O'ring? Any help is greatly appreciated. Dave
