The fuel line splits ant goes to a pair of T's. One feeding the left two carbs and the other feeding the right two. This T is where I am leaking. I have to split the carbs to get to these o-rings. Will I need to Sync them when it's all back together?

Thanks!!!

 

Funny I'm having to replace those same orings on my 91.

You shouldn't have to resync the carbs if you just pull the outter 2 carbs off to replace those orings on the T's
