Could do with one near my house.

I love the fact that agricultural diesel in Southern Ireland is green, not red

Didn't HMRC relax the rules about home brewed biodiesel recently. Something like you can brew up 2,000 litres for personal consumption without paying tax on it?

They use sulphuric acid to disolve the Quinzarine dye, they they wash the solution in water to remove the acid, as the acid is soluable in water. Then separate the oil / water, to complete.
Acording to my son (Studying chemistry at Uni) it works for both red and green dyes.

The downside is these are crims, and dont care if its not completely acid free. Hence you could have the internals of your fuel system eroded by the acid. Certainly a false economy. A new Diesel pump is in the region of £1000 plus.

Its probably a lot easier, and certainly more legal to make bio diesel from Waste vegtable oil. and a hell of a lot safer with far less toxic waste products.
You only need Sodium Hydroxide (Washing Soda we use for Electoyolitic de-rusting)
and Methanol, which is expensive and very flamable.
Methyl Esther Bio Diesel is fairly easy to make. You are really just extracing the Glycerine from the Veggie oil.

You can even register with Customs & Excise and pay the Tax, works out at approx 55p per litre tax paid. Depending on your supply costs (for new oil, obvioulsy less for waste veg oil).

I think there is a 2500 litre tax free limit for personal use, but dont quote me.. check with Customs & Excise first.

i used to use veg oil in my old car but think it might be why it had 2x new fuel pumps under warranty and after warranty i ran it on derv it was fine lol

Depends on the engine, and more importantly the type of diesel pump.
I use up to 50% SVO in my Bosch-pumped, XUD Xantia, smells a bit "chippy" but I can live with that. What I can't live with is the rocketing price of Rapeseed oil

there was a wacky backy farm across the road from me it was raided and there was a high speed pursuit and chinese people everywhere and i never saw or heard a thing or smelt anything

I have just had an idea for a new book:

"how to build an illegal fuel plant and not get caught"

Could get quite a bit of bussiness from us lot

Ran my !.9 Clio on veggie oil and 3%white spirit for a while. Clogged up two sets of injectors. So when cold left a massive smoke screen. Performance when warm was fine and the chip pan smell is preferable to real diesel. Bit of a giveaway to any plod in the know however. I wouldn't do it again without looking into it further. Have heard u need a bigger diameter fuel pipe.

Washing Soda is Sodium Carbonate NOT Sodium Hydroxide!

During the last few years I have been working as a petrol pump engineer. After seing what recycled chip etc oil does to a pump unit I would not touch it with a barge pole. The pumps are designed to pump millions of litres and the one with chip fat diesel flowing through it had to have new filters every other week, 6 sets of blades inside the pump and two complete new pump units during its warranty period due to wear problems. It was even alleged that to stop delivery problems some of the filters were removed. So all the filtering of the fuel will have to be done by the fuel filter in the vehicle. Also most people selling chip fat diesel dont add enough anti coagulant so the fuel can thicken in the cold weather. Dont be fooled into thinking that it will be automatically covered by a warranty a friend of mine bought some which clogged his system and it cost him almost a grand to have it put right.
