Hello i have a question on a polaris 2001 trailblazer 250 2 strokes the lines that are connected to the the "T" on carb where have to be connected
Thank you
Alberto

 

All that the tees and check valves do is confuse people. Chunk both of them if you still have the valve also.Run separate lines on the upper vent(s) zip tie them to the choke or throttle cable and terminate them under the tank. Run another line at the bottom of the carb past the bash plate for the carb overflow/drain line.
I saw plenty of them looking like this one.
