where can i find a diagram of the vacume routing for a 1990 polaris trailboss? on the carb.

If your talking about all the hoses on the carb then they aren't vacuum lines. They are vent lines. What problem are you having with the machine?

Vent lines? I'm having a problem figuring out where 3 line connect on a 01 Honda 350 4x4ES Rancher. Everything is connected on the carb as far as I can tell. When the engine is running 2 lines seem to be sucking and 1 I can tell. 1 originates from the top of the carb and runs into a T connector and then runs to an undetermined place within 8-10 inches. for the life of me, I cant figure out where they go. Can you offer any guidance ? Thanks

those sound like just vent/overflow lines. you normally only have vacuum lines on a carb if it the motor has a pulse actuated fuel pump on it.
