Guys,
that's not for BIODIESEL, It's for SVO (Straight Vegetable Oil)... If you decide to go SVO, and have a supply you can count on, and don't have warranty to worry about, and want to go without any taxes or fuel surcharges, and want to handle alot of grease/oil including filtering, and be your own supplier.... This is for you!!!
It's quite doable, but certainly no mainstream affair. The Really Good thing about is that you won't be running a chemical plant as you do when you make actual BD. Also, it was pretty much SVO that Diesel was thinking of when he invented the engine we talk about in his honor.
SVO is not for me... but I can't knock it if some people have had great experiences with it as they say they have had.
