Alright! I think I have it.
I ordered this piece from Summit:
https://www.summitracing.com/parts/s...690b/overview/
this piece from Jegs:
http://www.jegs.com/i/JEGS-Performan...15946/10002/-1
and Advance Auto has the polyarmor hardline to go from pump to 5/16".
Summit advised that -6AN was 5/8" so I wanted that fitting to be able to connect to 5'16".
Jegs told me the fitting on the Carter pump I have is 1/2"-20 and that is what Advance has on their fuel line.
I should be able to complete the (temporary) pump to carb fuel line Monday or Tuesday!
