FWIW, the '68 parts manual shows only 5/16" for the fuel supply.

What would be correct for this car? 5/16" I'm guessing, also, would there be a return line of any kind?
Thanks What was the factory transmission for this car? 4 speed for automatic? It makes all the difference.

Ive never owned a 1968.
But. Have owned 4 of a 1969 GTXs. All 440 cars . And none have had the 3/8" main line.
All 4 have been 5/16 with the 1/4" return line. 3 of them St Louis built....1 was Lynch road i think I might be wrong but I do not think I have ever seen a 68-70 tank sender with 5/16 and a 1/4 return. As far as I know they were only 3/8 and 1/4.

I can tell you that my 68 Dodge R/T with a 440 and auto-trans had 3/8" fuel line from the factory. Interestingly, A12 (440 Six Pack / BBL) Roadrunners and Super Bees had 5/16" fuel lines, at least that's my experience.

that is correct, because A12 cars are 383 cars with a drivetrain upgrade & the fuel system was NOT modified/changed

Well... Found a pic during the tear down.. but cant post it for some reason.....Looks like 2 lines for sure.. So would you say 3/8" and 1/4" return line with a fuel separator? That sounds right to me.
