280SL metal fuel line sizes

[RandyB]

‘69 280SL with blocked return fuel line. Have removed both rubber hoses on either end and I have tried everything I can think of to clear it with no success. Plan now to replace both the metal fuel supply line as well as the fuel return line. Have searched this forum and elsewhere and cannot find what size these metal lines are. Not confident to simply measure them as there is enough rust/corrosion that precise measurement would be difficult.
