Hi Ibster.
No, not at all, you don't even know its there, they really are very simple systems. Its basically two sections, back end and front end and the only thing linking them is a 6mm plastic covered copper pipe (oh,and a wire) ! With the tank being in the spare wheel well, i do have to leave the spare at home and carry a can of tyre repair, which would be good enough to get to a garage if needed.
Pretty much tucked out of the way.
Cheers and nice diesel BTW.
Andy.
