IMHO the metering rods and the Jets combined are the total orifice size.
The hole area minus the rod is is the total area of the orifice.
That being said, bbd Jets are non existent. If you have extras you could drill them.
Keep in mind the OEM fuel sender was not designed for achohol, no idea what it would do to it.
Unknown about the fuel pump, the volume is probably going to be ok, but can it withstand achohol?
Hoses that are new last 5 years will probably be ok.
I had a variable fuel car from 92 and when I needed a replacement fuel pump, I called the manufacturer and was told that all of their currently sold products were achohol safe.
