I am trying to identify the threads on an EGR (exhaust gas recirculation) fitting to be installed into the exhaust manifold of a 1999 Ford Expedition. The major diameter is 1.05 and the thread appears to be 13 TPI. I can't find any standard to which this fitting adhears to.
Could it be a special SAE thread. I have looked thru SAE J514 REV Jun 1998 and I can't find anything with the 13 TPI. Any help would be greatly appreciated.
