Fuel hose

David Silver spares have fuel hose.
What is the correct inside diameter for a CB77?
Petcock to carbs and crossover from right side to petcock?

8mm on the crossover, 6mm from the petcock to the carbs.

Thanks, but I don't understand the 8mm.
Now that I think of it, perhaps "crossover" was not the correct term. It is the right side feed to the petcock (CB77).
The 3 nipples on the petcock and the one on the right side of the tank measure barely 7mm. at their widest.
I was more wondering if D.S. Spares 5.5mm fuel line was necessary as opposed to 6mm available locally.

Sorry, I read "CA77". My bad.

CB77/72 petrol pipe ID 5MM according to Bill Silvers book and 5mm worked ok for me.
