I'm just about done installing my nitrous kit but alittle confuse on how to connect autometer nitrous gauge. What's the big hole for and what's the small hole for on the bottle? Does the autometer line go on to the small hole and the nitrous line go on the big hole? Or does the guage line and nitrous line hook up to the same line? If so what do i need to get to run it off one line??

Your help is greatly appreciated~~
