Diesel Descisions

Reading this months Canalboat Magazine about the future of the use of red diesel on boats got me to thinking about what we should do regarding fuel tank layouts in our hull. Bearing in mind we are having a seperate generator fitted should we have this on a seperate tank? surely that would still be okay to run this on red as it is our power supply but you could argue this case for the engine (and I wonder if it does change will boatyards keep stocking it?) Or should we risk the one tank. I reckon the EU will win this one...............Dont they always. So if we go the 2 tank route then we have got to deceide how to split the tank 75/25 or what. Really not sure which way to jump perhaps I'll just contact The Iranians and go for a Nuclear fuel cell bet they won't tax that!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! The glow would be pretty handy in tunnels though.
