I've read this thread with interest, having previously replaced the small ICV breather hose with some difficulty ( but I've been afraid to tackle the long one). Do either of you have any tricks for attaching the shorter hose? When I did mine the second time, when i pulled on the hose to remove it it came out attached to the plastic barb, and I discovered it was much easier to attach the hose to the barb outside the car and then put the barb, with hose attached, into its hole. Thanks.
