I went round and round ... up and down... sideways and all over the universe to different tooling places around town looking for a BSPT tap as well as online....
Finally - I Bought a 1/8 NPT Tap and used it on that location.... threaded in my new oil line elbow there.... and it worked perfect with no leaks. Was a little "tighter" than it should have been when threading in the elbow but worked !
