Hi,
My references can be researched/accessed from
www.journeytoforever.org. If they do not have the answer they have links and REFERENCES to books, journals, articles, peer reviewed articles, experiments, etc.
I am not sure about the copper tube heating coil inside the VO tank. I have stainless steel in my head from a post somewhere, but cannot tell you why at the moment. Please read/search this site for the proper tubing. SVO/WVO will work in a two tank system as long as the engine is started/stopped on diesel and the VO is heated properly for flow. For VO to reach the same BTU's as diesel it has to be heated to ~400degF. Since the engine is running 180-200degF there will be some difference in energy output/performance of the engine. Not really enough to notice or care.
My comments regarding the undocumented/unreferenced posts are preceded by a ***

ULSD has zero issues.
The issues of ulsd are known, so zero issues is quite far off the mark. Even Giles has comments about this on his website.
***Many believe that sulphur is the lubricant, however it is not. ULSD has had the lubricity removed during the sulphur removal process.

There is no such thing as a good single tank system. Elsbett makes crap on par with Lovecraft for the simple fact its a single tank system.
I didnt mention single tank systems, neither did the OP, not sure what you're talking about there. I was simply pointing out you were very wrong when you said "There is no way to run an engine on raw VO without long-term damage." Clearly this isn't the case. See also the post here where somebody has clocked up 6 figure milage numbers on veg oil.
***WVO/SVO has different qualities. For example, rape seed oil (canola) has the best lubricity along with peanut oil. There are others with less lubricity, but all have a better lubricity content than ULSD. The lubricity of these oils creates less friction and wear than processed diesel.

Engine oil contamination, accelerated carbon buildup in the combustion chamber and piston rings, excessive wear of the injection pump elements, high exhaust emissions and hacking of the vehicle body to fit the conversion.
Engine oil contamination, thats a good one, so you have zero blow by running on diesel? I would like to see the evidence on accelerated carbon buildup etc, i think you're just making it all up as per usual. You have read this somewhere and quote it as fact, without really having a clue either way.
I wont mention that veg oil is almost carbon neutral, so emissions isnt a major issue anyway. Oops, i mentioned it.
***Engine oil contamination is present in every engine albeit in different levels.
***Accelerated carbon buildup has been discussed with motors that have EGR's. i.e. TDI
***Injection pump componants last longer using VO as long as the seals are biodiesel/ULSD friendly
***High exhaust emissions is vague and misleading. Vehicles produce COx whether on petrol or diesel. On VO the emissions change to NOx.
