Return fuel hose size?

[lanciamad]

Hi all,
does anyone know off hand what size rubber hose is the return fuel hose off the carb of a 1600?
I know it's smaller than the supply line, I want to say about 5/6mm?
The car is elsewhere and I remember it needed changing when last parked up/ran. Would be useful if I can get some hose before seeing the car next.
Thanks, Marcus

Fairly sure is 6mm.

Managed to get some 5mm on, leak free and back running
