so I received my hot max needle valve today, and I have a couple of questions. which side is the ''in'' side on the valve ?. its not marked with a flow arrow but im guessing its the female side. also should it be installed right off the regulator or further downstream in the hose?. thanks in advance for any help. I hope this gets my masterbuilt dual fuel under control !.
