Could someone please tell me the correct thread opening sizes of the 90 degree connectors on the top of the fuel pump?

I took it off to rebuild the pump and now cannot find the 90 degree connect that goes from the fuel tank to the top of the fuel pump.

The pump is for a 1928 533 6 cyl and has eight holes on top. I tried a couple different connectors but I may have my FIPs and NPTs crossed...

If you have a picture of the pump with fitting sizes, that would be very helpful.

You may give Scott Henningsen a call out in California. He is who we used to rebuild a customers unit at our shop as well as a new Detroit Lubricator carburetor that he reproduces and he is very helpful.

If you still havent gotten this resolved, our customers 29 Packard will be coming back in before too long and I will snap some pics for you.
