It’s a ‘39 216. After cleaning it up, it is a cast brass T. Going into the engine is indeed a male 3/16 pipe thread, going out the top is a male flare 1/8” for the copper line going back into the block via another adapter, probably 1/4” threaded into the block. The horizontal exit out of the T is the female one shown in the pic and the local hydraulic hose and bearing specialty shop guy says it is a double flare 3/16”. This is what I need adapted to my 1/8” pipe thread hose that goes to the bottom of the old time fram filter. He says his modern 3/16 flare is different and will not seal as it bottoms the threads out before sealing. Whew got that? Lol still unsolved. Need to replace this odd T to something adaptable.
