From what I gather, there about three different fuel inlet sizes for QJ. The 68 toro carbs are kinda odd too....so...I think you are looking for 7/8 or 5/8 fitting with either 14 or 18 threads per inch. Just not sure.

The one at the parts store you found is the most popular size, 1" by 20 threads. These should NOT be npt threads, but SAE or to be a little more confusing, its possible an AN fitting could work, but just not sure.

I would suggest you keep looking and don't give up. I would try to get you in contact with a couple of people on the ROP board-Shurkey or Octania but the server is just too dang slow right now, as I think they both probably have an inlet for you.
