It would be the tube in the trunk on the right-side, could use just the vent tubes (five lines) or a whole unit. Someone used to make these but they stopped a while back.
My mechanic say we don't need that venting attachment thing. He just wants to put a filter on the end of the venting line. I have seen a car that wrapped the line from the trunk under the car and in the frame. Thoughts anyone? Many of the replacement gas tanks don't have the four nipples either.
