HELP! I took this thing apart weeks ago to repair tranny and can't remeber the hoses! I have a 97 Trailboss 250. I know which one is the gas line and then there is a bigger vent pipe next to where the choke cable goes in. THEN ther are 2 other hoses that are connected together by a Y. One goes goes to bottom of bowl (Vent I assume) and the other goes on side back towards air box connector. Like I said, these 2 are connected by a y connector with a single hose at the end. WHERE DOES THIS HOOK-UP TO OR ARE THEY JUST VENTS?

I don't have a manual that shows how the hoses are routed.

Thanks!

 

they should be vents if there small dia. hoses. maybe the other hose is a return line or vacume line. they may go up towards the handle bars as thats the highest point. just a guess mind you w/out looking lol.

 

They are definitley small diameter with what looks like a filter in the single line where it comes off of the y-connector. The "filter" says "Vaccuum" on one side. I cannot find any other place on the ATV to connect it to. I'm not sure which side should be vacuum or where (if any place) it connects???

 

i had the same set up on a 250 trail boss one went to the vent by the choke cable and the other went to the one by the air screw, on the other hand i got a replacement carb and the choke vent is connected to the float bowl overflow??? now i cannot start the dam thing with either aaaaaargh??!!??!!!
