exactly. I know you're aware of this but my post was for those who weren't. If they have a 3/8" steel barb and wanted to add some braided line to it to go to the carb for example, by that chart they'd buy #6 and it would be almost impossible to get it on the barb, id too small. #8 would be the correct choice. Just trying to save someone from buying the wrong stuff.
