You can do it like they come stock and run all of them down where they will suck up water and mud or you can fix the design problem as follows.
I run the vent hoses that exit the carb pointing up into the air box and the ones that come out horizontally get run down between the lower shock mount and the linkage dog bones. The float bowl drain gets run down too.
You may need to cut the black band that secures the hoses together so you can run them different directions.
With this modification, the carb can "breath" clean air from the air box even when the lower vent lines are under water.
