Hey all, I'm going to do the extended vac line mod for future carb sync jobs and i am trying to get a definitive answer as to the exact ID size of hose to use, can anyone tell me exactly what size hose to buy for this job? as iv'e read soooooo many conflicting threads 'n' answers it's getting confusing. Thanks in advance.

Any further info on the I.D. size peeps? Ideally would like to buy some hose tomorrow if I can get the info on size.

I don't know the answer, sorry. However, there are a few sizes of hose on the carbs, couldn't you try different pieces till you get one that fits and then use this diagram:

to check the size. The sizes are marked in mm.

Another suggestion - if you look at (org member) Tamsen's carb balancing video :https://www.youtube.com/watch?v=N7U5SwoOJto at 1min 56 secs she pulls off the vac tube to the fuel valve (on tank) - you could measure that since it's relatively accessible.
