Diesel water removal

I'd say just put it in the tank and let settle for a few days, this will get the bulk of the water out once you drain the bottom.
The rest you can filter through filters above as you have proposed.

Even after separating what water can be easily removed it is a good idea to mix a water removal compound with the fuel. These compounds mix with the slight amount of water "dissolved" in the fuel. There are test kits available to see if there is a trace amount of water left in the fuel. Last but not least, use an additive that will prevent algae forming because of the water. The algae could end up being your biggest problem as it can not only be in the bulk fuel tank but in the fuel tank and fuel lines of the equipment.
You are on the right track to use good fuel filters but I highly recommend you test to see if water is still in the fuel and add a compound to completely eliminate the water. Beware of algae forming.

Hope it works out as fuel prices are even ridiculous in the states also but not quite that high.

the best way to clean the fuel is centrifuge it. followed by fine filtration. yes you can use coalescing filters but you will be changing them regularly and the cost will be high. depending on volume of fuel and if you have other uses for it centrifuge is the way to go.

nearly all ships use centrifuges as they are ever reliable and give good performance with very low cost. they can also clean multiple liquids from fuel to oils and even bilge water.

the cheapest water separating filters are the delphi(lucas/cav) 796 filter water traps the elements are around 8 bucks last time i bought one. the whole filter unit is around $50 bucks with the glass bowl metal bowls are available and so are poly carbonate.

as another has suggested you can let it settle out angle the tank so it settles to one end.

most good fuel conditioners and injector cleaners have additives to disperse moisture but are only designed to handle the trace amounts in already filtered fuel.

D4Jim, do you have a recommendation for the testing kit that you mentioned? I also have read about THIEVING PASTE which was used to sound tanks on large vessels. It was wiped onto a stick or rod and when dipped into the tank, the water (if any) at the bottom would change the color and show how much water there was. I have asked about thieving paste in auto parts stores and nobody had any idea. In the yachting world there are services that come to your boat and "Polish" your fuel. It is pretty common and might be available in other than boating areas. I think this is going to be an important thread. Grant.

I know that Shaeffers does the fuel testing and polishing.

I'm not at the farm right now so this is by memory. The paste is called Gasolia or something like that and is a a water seeking paste and changes from yellow to red when in contact with water. Water at the bottom of the tank will turn it bright red. For water "dissolved" in the fuel I checked it with a test kit for determining if gasoline has any ethanol in it (pony fuel). Can't remember the name of the kit but cost about $70 and I use it on the diesel also as it actually checks for any water content. That being said I add Power Service, and there are many others available, to my fuel as it also adds lubricity that was taken out years back when they deleted the Sulfur. I would absolutely use an additive if I found any water in the fuel to prevent algae growth. My neighbor had problems with it and it was a mess to get cleaned up as he had to remove the fuel tanks for thorough cleaning. Like the fuel caps say "use clean fuel and keep it clean".
