I had one fitted to my curvey, wouldn't recomend it.
As there is not much room under the tank where it was mounted it caused the line to get snaged and eventually split, resulting in a interesting moment as my bike almost caught fire
However that was an in line filter and was quite bulky, I belive the type that allow for a quick split of the hose is smaller so may fit a little better.
Either way the fuel is taken from the tank via a pump so if you disconect the pipe with the engine off all that will come out is a little petrol that is left in the pipe.
