Carb Sync

[beaker]

I'm going to sync the carbs on my F80TLRY this weekend. I was looking in the manual for the typical or max vaccum pressure in the intake manifold so that I could be sure that my manometer tube is long enough to keep the fluid from rushing up into the intake. Am I missing this in the manual or does anybody have this vacuum pressure off hand from experience? I can convert units if you got it in psi or inHg. Thanks ahead of time.

No I don't recall what the actual vacumn reading is. We just use the bottom carb reading as the base and adjust rest to match it.
