AS long as you are talking about just the flexibles between the pipework on the hull and the engine my guess (and it is only a guess) is that will be OK. This is based on a statement by a major British mariniser that the only thing that needed doing on their engines was to fit an electric fuel pump. Personally, at the moment, I would be far more concerned over how often you will have to change the filters because bio-diesel tend to be very "cleaning" and carries all sorts of muck through the fuel system initially. Also take care because it absorbs water, rather than just floating on top of it so it might be an idea to start regular use of a biocide additive to prevent fuel bug problems further down the line. Also keep the tank full throughout the winter. To be honest I think I would try to end up with almost 100% ordinary diesel in the tank by November and start using bio again in March until it is in much greater use and we begin to see the problems or not).
