I went to the local hardware store for the clear tube. I ran the clear tube through sections of black rubber hose from Auto Zone to protect the vent lines from heat and anything the tires kick up.

Mike do you remember or know the size line you used to run the 1/4" clear through?
I am guessing 3/8",but not sure.

That is a great idea. Thanks!

Ok,
why couldn't you just use the black rubber hose and forget the clear tube?

Doug
Two reasons.

1. I only needed to protect a small section where it was near the header and tire
2. I wanted to use vent lines the same size as the stock one's

As far as the size I matched the factory size for the clear tube and took a section with me to Auto Zone to get the right size. It was about $3 of rubber hose.

Thanks Mike.
I wasn't sure of the reason.
I am redoing mine this Saturday.
I think the vent tubes are 1/4" ID. that I need.
Someone correct me if I am wrong before I buy the wrong tubing.

Best thing you can do is ditch the vent line all together an install Bellows.
Link to a thread discussing them.

You want to get the can am bellows. They are about 5 dollars each.
I used bellows for the front diff but you can't use it for the fuel vent line. Since I needed a vent line for my fuel tank anyway I tied my fuel vent line, engine breather, and rear transmission/diff vent line together and ran it to a small K&N filter at snorkel height.

Another thing you may consider. I added a loop in one section of the vent line to help trap water. You'll get some from condensation.

As far as bellows are concerned..
I am not familiar on how they work.
Where does the heat go since they are sealed?
Sorry if it is a dumb question.

The vent isn't there to let heat out. The aluminum case does a pretty good job of that. Its job is to let the case vent for pressure differences from cold to operating temperature. The bellows allow for that expansion without allow water or dirt in. Think about what happens every time that diff gets hot then cools down. An open vent allows moisture to be pulled in and allow condensation in the case. Thats not good for the fluid or anything else in there. The bellows seals that all up while still allowing for expansion.

UPDATE...

I have ran the hell out of my 50" since installing the bellows.
I could not be happier.
Awesome idea.
Thanks everyone for the advice and part numbers.
