Those of you comtemplating running WVO in your diesels should do a google search on the subject. There are numerous websites devoted to this fuel. Unless you live in a year round climate that stays above 50F, you will require a two tank heated WVO system. Here are a few websites for kits and forums.

As has been posted on other threads, filter the WVO to at least 5 microns and check for water. Water will ruin your injectors. I have driven my Ford powerstroke on WVO and can't tell any difference in performance between WVO and diesel.
WVO will power your benz!
