i live in northern california, the temperature in winter time never drops below 55 or so, and in the summer it goes well over 90. do i need to heat up the fuel still? also, would it be possible to do a 50/50 blend of diesel and vegetable oil, and still be able to start my engine on it?

@KLX1990 Yes and No, No and Yes. You must heat your oil or you will destroy your fuel system, specifically your injector pump. I now firmly believe you have to heat your diesel as well for the flush, hot diesel will clean your injector pump much better then luke warm diesel. Picture hot oil followed by just warm diesel, that oil will gel before it gets flushed out. You can start your engine without it, but don't expect any reliability, expect a breakdown.

is that the only filter you use ? a 30 micron filter.....what do you filter your oil to 10 Microns or less ? I had injector pump problems with the Veg Powered System I got in Ojai...I think he even sold me a used tank. do you advise putting an inline filter say 10 microns or less to protect the pump ?

@alwaysreadyrob I use synthetic fabric bags that I buy from McCaster Carr. I have learned that gravity feeding the oil at room temperature is the best way to filter used oil, don't heat it up because the animal fats melt and go through the filter. In my diesel I use a lot of Marvel Mystery Oil and Sea Foam so that there is plenty of solvent in my diesel to clean out both the injector pump and the injectors and injector lines. By plenty I mean a bottle per 20 gallon tank.

I have a buddy that ran for several years in his Mercedes. He said after a while (unrelated problem) he pulled the engind down. The glycerine had built up on some of the internals. I think you could probably run some diesel and water to clean it up if you did it every 10th tank or so. BUT that is just a guess.

@seawalkersee Yeah, that's what I've heard. I run Marvel Mystery Oil inthe oil about 200-500 miles before an oil change. I think that's cleaning the stuff out pretty well. A freind of mine ruined a VW passat (1990's) model. It recommended 10,000 mile oil changes so he went with that, and the vegetable oil was contaminating his engine oil. So if you run some SEA FOAM or some Marvel Mystery oil in the motor oil I'm sure that will keep it from coating up too much.

super awesome. i hope to be running my 7.3 on veggie oil soon. thanks for the video.

@Motion63Films The water pump seems sufficient and yes, there is additional fluid to add so that you have fluid in the 10 feet of extra hose. Maybe half gallon or more. The only flaw in this design is cold weather flow from the tank and I did not initially account for the return line to the fuel tank, the factory return line.

@LUVallova Well I've used it a little over a year after I got it and it was fine. My problem is that I have too much oil to burn, what a nice problem to have huh? I've got some oil going on about 3 years old now, so we'll fine out pretty soon if that's still any good. I suspect it's just fine.

How long does the fuel stay stabile? My 95 powerstroke sits sometimes for a couple weeks. I only put 4000 miles on in a season.
