I've got a question and hopefully someone can help me out. I was told by a tech from thematrixcenter.com that i need to hook up an output pressure gauge to my Matrix so I will be able to tell at what pressure the in-line reg. is operating at. Thats all he told me, and I am a little slow so if anyone can tell me how to go about getting an ouput pressure gauge and how to hook it up I would appreciate it. Thanks
