Biodiesel should have no unprocessed veg oil in it or chemicals added to make it thinner. If you buy any, take a pop bottle 1/4 full of water with you and ask for a sample of thier biodiesel, put the same ammout of biodiesel in the bottle as you have water and give it a good shake, after 1 to 2 min's you should start to get clear water at the bottom. If its white its crap fuel and don't buy it. Also check they make it to the EN standard. Loads of common rail engines are fine on biodiesel but do not use veg oil in them £000's worth of pump damage. Some engines have a problem with the DPF as biodiesel runs cooler then dino and the cleaning cycle dose not clear it correctly. I would not use silicon tube, modern fuel pipe is not rubber based anymore and is fine with biodiesel.
