When I was taking classes at the community college, Marty Hanka came by and gave us an up-close look at his VW TDI diesel he was running on waste veg oil. We heard it run, and we got to check out his setup. He'd replaced his spare tire with a tank for WVO, which had a coil in it that circulated coolant to heat the oil. The car started on conventional diesel, then when the coolant--and the WVO--was warm, the engine could be switched to run on WVO by the flip of a switch, with separate lines, solenoid valves, and connections for the WVO.
The veg oil was NOT mixed with the conventional diesel fuel!
After running on WVO, before shutting down, the system has to be switched back over to diesel before shutdown...again, with the flip of a switch. That way, the WVO doesn't get the chance to gel where you don't need gelled fuel.
My thoughts on the system? Well, for a demo unit to sell folks on the concept, it could've used some braided stainless lines with AN fittings...but otherwise it was a super-sanitary install.
