Don't know if anybody here would be interested, but I have a waste vegetable oil conversion kit from Greasecar that was set up in my 85 740 turbo diesel wagon for sale. I pulled it out because I want to run biodiesel instead. It comes with a 15 gallon rectangular fuel tank, fuel filter heater, hoses, switches, wires, add-on fuel gauge, SV100 solenoids, extra fuel filter, and three vegetable oil strainers, all from Greasecar. I don't have any instructions on how to install it but the set up seemed pretty straightforward when I removed it from the car, and Greasecar's website offers lots of help and support. Brand new these kits are $1000+ from Greasecar.
I suppose I could ship it, I'd just have to find a fairly large box. Shipping would cost extra (i.e. not included in the asking price).
I'm located in Appleton, Wisconsin.
Asking $200.
