    Hi Guys ,
    Just need a quick bit of guidance on the hoses on the fuel tank. A pic of the tank is below.

    As I understand it, there is a drain hose (for fuel overflow around the tank rim) and a Vent hose. As you can see from the pic, these all seem to connect up, which I don't quite understand the reason why. if someone knows, it would be good to know.

    Embarrassing Question time - Just need a bit of reassurance on whether the following is correct : the hose at D (which I think is the drain/overflow) is routed down to the bottom of the engine/frame area, The hose at C is the vent, to install the TenKate hose, the hose is connected around A, and then this is routed away (to the vent bottle) without any of the Tees in the hoses.

    Thanks in advance for any help .

    Just thought I would give an update for anyone having the same question as I did about the fuel tank piping. After asking various people and doing a bit of research I decided to go with the suggestion from one of the technicians at Tenkate in Holland ( the Honda WBSK Team - their shop has very good customer service ).

    I bought a vent hose from TenKate and fitted it to the breather port. The over flow was blocked off and safety wired ( my understanding is that the overflow is in case of tank over-filling, which shouldn't happen on a race bike....).

    Here is a photo of the blocked off over-flow and the vent pipe connected
