Bought and fitted a DP carbon tank cap It has a breather hose however and the instructions supplied dont mention where the other end is meant to go. One end attaches to the filler assembly and this creates a 'hole' to the outside There is a black rubber breather on the top of the tank under the fier assembly and I assume the other end of the clear breather tube which vents to the outside of the filler cap is inserted into there? Anyone shed light? 1198 bike Thanks
