Tim,

pictures always would help. I tried brass in the outlet of the insert, it isn't NPT. I suppose compression. Makes sense if it was going to brakes or something more safety related. I may be able to get a compression / NPT reducer. Really, my biggest issue is I am trying to keep this thing as "correct" as possible. And I know that if I don't have this right, it is going to bug the crap out of me. I would really like to get right part that screws into the manifold for the truck its on.
