"Well, I’ve made a significant change to my WVO design. My original plan was to have 2 seperate fuel tanks. The first would contain regular petro diesel, and the second tank would have WVO with a heat exchanger (see below). With this plan, the vehicle is started on the diesel, and once the WVO has warmed up to coolant temp, the fuel path is switched to start injecting pure veggie oil. On Sunday I ran some viscosity experiments in the lab, and found that by blending diesel and WVO together, I can pour the mixture into my single existing tank and run it direct. I started with a 25% WVO/ 75% diesel, and found it ran quite nice. [...]"

You can also use kerosene or jet fuel. But this system is a bit suspect. Veg. oil thickens even when mixed and this extra vicosity could lead to extra coking of the injectors and engine. If you find that u have to replace your injectors prematurely then u should switch to a two fuel tank system. A 2nd heated fuel tank thins the veg oil to 10 to 20 centistrokes. Thin enough for most diesel engins. Joshua Tickell publishes a book: "From the Fryer to the Fuel Tank" the information is very good but somewhat dated. Just buy more modern veg oil fuel lines and u should be set. Also Filtering systems have come a long way. You should be able to diy for about 4-500. The book was only 18 dollars. Well worth the investment. Some conversion shops have systems that let u Fill Up behind any restaurant; thats right any restaurant anywhere becomes your fueling station, these installation generally run to around 2000 dollars but are well worth it. I started with a diy job and then moved up with the money I save on fuel. Good Luck.
