I HAVE used WVO in my dual diesel/wvo fuel 7.3L F-350 utility truck circa 2006. Truck got wrecked but I’m looking for a 7.3 van for traveling. I saved all the wvo innards from the old truck si I have a head start for the next conversion. (Some newer diesels with computer controls may not “like” wvo, but there is often aftermarket tuning software available to make various adjustments that may work, if needed.)
My wvo fuel system had a separate tank and fuel lines and a multi-port valve for switching back and forth from diesel (or biodiesel) to the wvo. The whole wvo system was heated with coolant from the warm engine. It’s a bit complicated but I got all the bugs worked out. I have photos of the whole setup. It was fun.
