Fuel & Coolant Breather Hoses

[Joseph Levandoski]

Anyone have an idea what material the breather hoses are made out of for the coolant and fuel tanks? Pulled apart my 'Winder this weekend and found the fuel breather hose was melted by the exhaust manifold. I'm trying to reroute these lines to dump in front of the engine - with the heat damage and melting, the current lines are too short.

I looked on the Arctic Cat and Yamaha parts fiches, but it looks like you can only purchase it by the 50 foot roll - I need maybe 5 feet in total once I'm done.

Not sure why these hoses would be where you show in the pic. They're both supposed to go down the left side (under the coolant tank) behind the aluminum strut in some holders and go under the left side of the engine and end up in the space where the oil filter is (between engine and front bulkhead. There's supposed to be some holders that guide and hold them down there. They'll never live being under the exhaust manifold, AND more importantly there is fuel vapor in the one coming from the gas tank so that could be very dangerous if it melted and caught on fire.

Everything was routed as you described, but instead of dumping out at the belly pan, they made a hard right turn and dumped under the manifold.

I have no idea why they were routed this way from the factory, but I’m glad it was caught beforehand. I have found a new home for them by running them along the front left spar, but I need longer hose as these were damaged.

Yikes, glad you caught it before you had a fire! Good catch. Best hose to use is urethane tubing. It stays soft and pliable well below zero. It's readily available from auto parts stores, fleet & farm stores, lawn & garden shops, or online. I've seen it clear or blue usually.

Yes good catch those hoses are routed wrong.
