If you are going to run WVO be sure to do it right, do the conversion.
The AndysFord and misnomer speak of are IDI, PowerStrokes are a different animal and much more sensitive to fuel problems. What works for IDI will not necessarily work in a PSD.

If you do not get your truck set up properly you could be looking at a new engine in a little while.
PM FN74 (Vegistroke) he is the forum sponser.

If you dont want to convert the truck then make BD with the WVO.

I have an extensive study done a few years ago on running WVO and the potential problems associated with it. It is too long to post here but I will e-mail it to you if you PM your addy.
