Are you looking for the thread size callouts on numbers: 16, 12, 10, and 8? These are the common designations found on the CJ.

Which line did it come from? In the diagram I note a restrictor on the line that goes to the NLG actuator. Is that the one?

It seems that it is lodged between the ducts on either side which look to be riveted in place!

Someone please correct me if that is not so. The following is based on that assumption. The flare angle is the aviation standard of 37 degs. which is also true of all AN and MS hardware for =9Cflare type=9D tube fittings (there is also an MS compression type). If tube/pipe (rather than tube/tube) the pipe thread is universal. On the small 6 mm tube fitting it is 1/8=9D pipe thread. The same as AN, MS and SAE fittings. The tube end thread is metric but, like SAE thread, there are coarse, fine and very fine variants. The Chinese utilized Russian thread standards (why I assume the CJ and Yak are the same in this area). But I believe that Russia (and Eastern Europe?) used a different thread pitch for this purpose than Western Europe. It is possible to mix and match fittings, tubing and =9CB=9D nuts (with varying degree of complexity) utilizing AN and Chinese/Russian in the 6 and 8 mm tube sizes. Not too likely in the 10 and 14 mm sizes. It is quite possible that some Yak/CJ owners have used SAE fittings rather than AN standard assuming they are physically the same due same thread on both ends. Where SAE differs is the tube flare. It is 45 degs. (90 degs in SAE parlance) NOT the aviation standard of 37 degs. Hope that helps a bit.
