thanks! do you happen to know what hose size and NPT might be needed? I know that's a random question and looking at another skunk2 manifold that has those sizes it says: " Port 4 x 1/8 NPT, 3 x 1/4 NPT and 1 x OEM AIT Port", so I'm thinking of grabbing those 2 sizes and trying to see if I could get something from Lowes/Amazon to do the job
Sorry I forgot to mention I'm also using this https://www.amazon.com/EDGE-INDUSTRIAL-Degree-Elbow-Fitting/dp/B07CQQPG21/ref=mp_s_a_1_4?dchild=1&keywords=1%2F4+barbed+to+1%2F8&qid=1605568402&s=industrial&sr=1-4 so the check valve has to work with this.
