BC Broncos Hard Fuel Line - what size threads

[OsideDave]

I have had BC Bronco's single hard fuel line carb style kit installed on my 351W Bronco for many years. About 7 years ago I went to a FiTech throttle body EFI and their G Surge tank and now installing Wild Horses M1A1 tank with EFI in tank pump. I'd like to put 6 AN fittings on the BC Bronco's hard feed line. Does anyone know what threads the line ends are? And where to order the adapters? I am guessing they are 1/4NPT and would need 1/4NPT female to 6 AN male adapter. Wanted to have things on hand prior to tear down. Thanks

Assuming no one has a direct answer, do you have any pictures? There are only a couple possibilities and picture(s) would narrow it down.

It doesn't appear to say what they are on BC's current website, however they would appear to be SAE inverted flare tube nuts on the Ø3/8" fuel and Ø5/16" return lines, so best guess would be 9/16-18 and 1/2-20 inverted flare tube nuts. What they were 7 years ago I can't even begin to guess, but some pics certainly wouldn't hurt. FWIW, NPT would not be my first choice for fuel anything.
