There are many sources for info/parts to run WVO. I use the Lovecraft single tank system and it works well (15,000 trouble free miles on free fuel!). It is inexpensive and easy to maintain (permanent washable filter). I'm in California, so a single tank system works good for the Benz all year long. Injection line heaters work well with single tank, and are a benefit on a 2 tank in the winter. A 2 tank system is best for cold weather, and you can run hydrogenated as well (NEVER with a single tank). I heard a guy say he could put a stick of butter in his Veg tank, and it would burn it!
