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