I replaced the tube connecting with a male and female quick connect, and I replaced the air-in with a male compressor fitting. After a bit of tweaking I was able to get the spray coming out of all misters without any major leaks. The initial test was done with a bike pump hence the sporadic spray so next I will test it with a consistent air in from a compressor. Overall I am pretty impressed with the spray under low pressure (20 psi) I think if I can run it at 30-40 psi it will be a very nice consistent mist. I am thinking I may run into issues when I try to run anything else but water through this system...only one way to figure out......
