Wonderful post, RCAVictim.
Let me just say that I first ran ULO in a diesel engine in 1958. It was an IH 6 cylinder which was started on gasoline and once warm, changed over to a kerosene/ULO mix. Since then, have more hours operating equipment, vehicles, and airplanes than I care to think about, and yes, a fair amount of it was using alternative fuels.
Have used heating, treating, and diluting for alternative fuels for a long time, and the same rules apply no matter which fuels (hydrocarbons) are used. Yes, the applications vary. No, since you are comfortable that you know about your engine(s), and obviously, fuels, will not detail my humble rules, processes, and formulae. Am certain they would not help you in any manner, anyway.
Have also had about as many issues with hoses and fittings cobbled together as anyone, and most of those were from my own failure to follow good practices.It is always so much fun to blame others though, isn't it?
You state that I am an expert on your own physical plant. I assure you, I am not, and have no desire to ever even look at it. And, the day when you and I are intimate will be one cold day in He**.
Let me write this in a clear way: Acetone in ratios of 1/250 to 1/1200 (1-5 ounces per 10 gallons of fuel) mixed in fuel does not cause vapor bubbles.
Please continue, I will not respond further to dampen your joy in being a victim (again).
