My 28 project doesn’t yet have an oil line to the feed pump.

Can anyone tell me the thread form and size of the stub on the base of the tank .. looks around 9/16 in, I’m guessing unf but how many TPI.?

In R&O parts list it is noted as (corrected F.No 28 B 77 S) 9/16-24tpi.

Some repro tanks have a courser thread there, just had to make some fittings for one. Let me know if yours is non-standard, will check what I used.
