How long after switchin do I have to turn over the return line? What type of milage do you get? Same as diesel? How do I get a custom tank for the wvo? Who should I ask to build it? Confused in TO Ont Canada.

Hi I have a 2005 cummins, I plan on converting to wvo do you have any suggestions for, or do I need an additional lift pump, if so will a holley blue fuel pump work. How do I set up 3port valves and checkvalves also heard should use 6port switch, What is better? Where can I get sock filter style? Do I need that style? what is the best for the money! For prefiltering wvo thanks ,8ball

What type of conversion did you do to your truck or are you running straight waste oil in your fuel tank?

Where did you find a water blocker filter? I havnt heard of these. Thanks, Dan

Curious if you or anyone out there would recommend a kit. I am looking at a Golden Fuel System and would like to know the pros and cons of anything else out there. I am also interesed in possibly doing one myself if I can find out the necessary parts..I just need to know if I need a FASS pump or not or run a 12v aux pump only. Has anyone out there used the Griffin filters in the racor housings, as I would like to know if they work as well as the Racor Aquablocs.

Hello everyone,

My name is Adam West and I work at fossil free fuel. As far as running the newer common rails on veg, there is no problem. They do use quite a bit of fuel so high flow valves are recomended. I have an 05' that I am converting this week and I don't have one worry at all in doing so. The key to any kit is lots of heat, and just to make sure that the work is of a quality job. If it isn't done well the oil might not get hot enough, there could be cross over contamination, there might be air leaks, and the fuel system could just not get enough pressure. I just started working at fossil free fuel a month ago, and I think that they have the best kit available hands down. They make all of there own in tank heat exchangers, filter housings, only use flat plates, and use the best valves possible. All of the materials and some of the best, and most all of our fittings are jic quick disconnect for easy service. The price of a good conversion isn't exactly cheap, but it is a lot less then the cost of rebuilding your engine after a lovecraft system has been installed. I hope that this helps some of the people who are a bit skeptical, and that they will soon be converted to the good side :) . Fossilfreefuel.com is our site, our new site will be up shortly though. Hope everyone has good luck in there conversion's and feel free to call with questions about our kit.
