I have a 1995 Ford F-250 Power Stroke with just 200,000 miles and new lift pump. I want to convert it to WVO. Can one of the two tanks be used since it already has the tank switch? I know that the F-250 alos already has a heating system in the bottom of the fuel filter, what more is needed to convert? Can I buy already filterd WVO in my area or do I need to set up my own system? I don't have a lot of start up money so used stuff wuold be great if available. I have worked on my own vehicles, plumbing and electrical every since I was a kid and I have the tools so I have the mechanical ability to do what ever assembly is needed.
