with mine, I tap into the engine fuel line as it leaves the tank. Not the return line.
I didn't use a separate tank.
Better to use a separate tank, that way you can do the kero flush at the end of the season and add kero to the diesel to make winter fuel that the diesel heaters were designed to run on. They are really modified kero burners so straight Aust diesel isn't the fuel they were designed to run on> The closest thing would be heating oil that was common and cheap many moons back, before the govt decided they could tax the stuff and wreck an industry overnight. They did the same with LPG so they are not able to learn from their mistakes, no guesses to which side of politics went for the money grab. If you try to run one of the old heating oil burners they carbon up and fail very quickly, just like the diesel heaters we use in RV's.

Could you use veggie oil in diesel heaters, much better to smell fish and chips or curry than diesel, veggie oils emit about 80% less harmful emissions than dino.

The ash/coke residue is the problem with burning diesel rather than heating oil, so it would depend on the ash/coke level burning bio diesel or vegie oil. We have found the deep fryer oil change mobs seem to have the cooking oil market stitched up in most places on the mainland now because they process it themselves and use it either as fuel in the vehicle fleet or sell it to the oil companies. Bio diesel is the source of the lubricant added to low sulphur diesel to stop it chewing out fuel pumps and injectors, so there is a continuous market for it here as well as the rest of the world that has gone to low sulphur diesel.

I never have trouble getting veggie on the road and normally leave home with a full tank ad get back with an almost full tank, Naturally in urban areas the big wigs would have control but in rural Aus, have found they are happy to give you whatever you want, or they direct me to the local transfer station, which normally has stacks of it. One of my suppliers goes through 40lt per day as they change their oils a couple of time a day and it is so clean, that's the secret to good deep fried foods, clean oil. Have teamed up with another veggie oil users because now have 10 x 1000lt cubes of centrifuged clean oil and over 20000lt of dirty oil, which is stacked in 2 sheds and a couple of huge piles covered with tarps.
Would adding veggie to dino help with the diesel heaters to reduce the carbon/soot build-up, much better flow and lubrication and as you say, a flush with kero/dino at the end of the season would keep it nice and clean. On my vehicles, have a new system which uses 1lt of dino or BD to flush the fuel system out, saves a heap compared to driving it for at least 12klms to flush it out.
Ah, you run on neat vegie oil rather than bio diesel, that is the reason the flush is required. Veggie oil does ash when burnt, you can see this by the way it smokes and goes black if overheated. It needs to be a product that simply vaporises when sufficiently heated, no smoke as such and doesn't change colour. The diesel heater is actually burning this vapour rather than the fuel in liquid form and the problem arises when there is a residue left behind once the fuel is vaporized. This burns into a carbon layer and clogs the mesh screen preventing the liquid from vaporizing properly. The kero added helps burn off this carbon build up because it vaporizes first and gets the fire burning quicker as well as soaking into any carbon deposits already there and aiding in burning these to an ash so they can be cleared out of the combustion chamber in the furnace.

I use a heat exchanger on my engines, would never run cold veggie in them. They do produce white smoke when sitting still for awhile and idling, when I take off after sitting idling for awhile, there is cloud of smoke but once running, no smoke at all and I do use BD for flushing when I make it, But 1lt per day doesn't really cost that much and in my opinion dino does a better job of flushing than BD and making Bd is very time consuming.
