Just remembered this it might be handy for veggie virgins
For info on running cars on veg oil
http://www.vegetableoildiesel.co.uk/index.html
More US based in terms of makes and models but there's loads in here too
http://biodiesel.infopop.cc/6/ubb.x?a=cfrm
and there's this
http://www.bio-power.co.uk
but that simplifys the needs of a new engine a little bit too much
and
http://www.dieselveg.com/
Which sells the stuff you'd need for a 2 tank system
and this which has a bucketload of info on injectors and pumps and a link to another database
http://www.doctordiesel.co.uk/
I have too much time on my hands
Wonder if one of the admin could make this a sticky so I don't lose it again
