Two ways to do it. Remove the needle valve and place the manifold there. I've not worked on an Azoo so I can't tell you if those threads are standard 1/8" NPT or not. If they are this method will work.
Second way is to just open up the current needle valve and run a in-line manifold with additional needle valves on it.
Either way you are going to need a manifold and needle valves.
