i used a factory breather from toyota that has a barb on it. it looks exactly like the stock ones on the axle but has a barb on the end. i ran mine into my gas cap filler. ill try and get pics today for you.

its one of the two breathers i circled. youll be able to know which one it is in person by looking at it.
