Hi all
We had water in diesel tank so I thought I would treat it with some fuel zorb.
It turned it this opaque colour which concerns me a little. I was expecting it to clear but it hasnt. You can just see the emulsified water particles at the bottom.
Engine is running fine. Did at least 2 hours of motoring and didn't miss a beat.
Does this look right?
Thanks

For that size tank it's fairly in expensive just to dump all the diesel, scrub out the tank and replace the filters. I would keep an eye on the clear fuel bowl of the filter/eparator and see how much crud collects in the bottom. The fuel tank will have a layer of sediment just below the pick up point that will get stirred up the next time you run your motor in adverse conditions!

cant agree more last thing you want is for the engine to fail when its rough and your entering a bar
Fuel zorb is a chemical hokuspokus which might work if there is fresh water in the tank from condensation, which can be held in check by keeping the tank topped up regularly, but not in large quantity of water from inundation, which might be your case. It might be sea water.
I would not use that hazy concoction in my precious engine.
Any diesel engine should have the following, in line:
Tank - sedimentor - primary fuel filter - (may be) secondary fuel filter - fuel pump - injectors...etc.
If one does not have a sedimentor fitted, one is well advised to fit one, if possible.
It's function is to take the water out of the fuel before it enters the fuel pump and the engine, causing problems.
It should be - like the fuel filter - drained regularly!

Yes I might have hit the space bar. Dumping $50 worth of diesel is the way to go. The snake oil "converts" the water, it does not remove it!
There are two types of additive that protect your fuel against the dreaded bacteria. One of them I believe is an enzyme based additive which will take up water as an emulsion and will go through the injectors. The problem comes with overdosing the fuel and you get cloudy fule forever. Keep an eye on the free water and it should be OK.

Hi Sir G,
you've got me really interested in a sedimentor, but I can't work out the fuel circuit you have from the pic - perhaps you can expand?

allan
dump the fuel ,you do not want that going through your pumps or injectors .do not use additives to remove water from tanks ,use quality filters and water separators only and drain off tank ,use bug killer only if you have diesel bug ,and have lots of filters ready ,as when you kill the bug it will end up in the filters
sirgallivant is absolutely 100% write this stuff is snake oil and his recommendation for fuel system is spot on.
that haze is water emulsified in fuel ,probably the same stuff they use to make soluble oil
I worked with trucks a lot in my life, past tense thank Huey, and all of them had sedimentors. My diesel Mazda had a sedimentor.
My boat has a same. It's a Vetus.
I am wondering, how a diesel boat engine doesn't have one?! It stands to reason. It is more likely to get condensation in one's tank on a boat than in a truck.
The plugging is simple, fuel hose coming from the tank then sedimentor in - out and so on. There is no magic. Just another filter in the line.
If you google it there is an explanation under 'fuel sedimentor'.
I use this stuff and it works. A tiny amount is needed only to keep the fuel fresh, the bio-bugs out.
Google it.
Allan, on the photo the big s/s thing on the left is my fuel tank, all 75 litres of it. Opposite on the wall is the sedimentor with the glass bowl. It has a tap on the bottom of it like the fuel filter which when undone let's out a bit of - hopefully - diesel, or water if there is any. Drain the water, close the tap, see ya in a month or two. (do the same at the filter!)
It is reasonably small, the bowl l mean, a schooner worth, l never had any water out of it yet. It is, of course, not for removing water from the tank if one had it inundated! Only condensation water.
The other things on the pic is the coolant reservoir, right of the sedimentor and in the right bottom corner the pong box.
I hope it clears it up for you.

Thanks Sir G,
My confusion was because I didn't know what I call a filter/water separator or primary filter, is also known as a sedimentor - duh!
I was looking at the filter/water separator and thinking ..."where is the sedimentor?" 
regards,
allan
