It's a vacuum gauge with a stopper on the end of it the size of the toilet bowl opening. You flip open the toilet ball valve, stick the stopper in the bottom of the toilet, then turn on the pump to pressurize the system. If pressure holds, then the leak is in the ball valve/bowl seal assembly. If the gauge starts dropping then the leak is at the vacuum generator.Hey Bill, do you mean vacuum gauge? They can be found just about anywhere. Or are you actually pressurizing the system to check for leaks? Shopping and learning, thanks.
