Moisture in the air will condensed . Example would be a bulk fuel tank made of steel sitting in a farm yard, and half full of fuel. That means the other half the tank is full of air. So the weather drops down cold over night and in the morning everything is covered with frost. Probably some frost inside the fuel tank too. Then when the sun comes up and gradually warms the sides of the tank, the frost melts to water and runs down the inside of the tank and mixing with the fuel. Won?t be much, but do this over and over again and it will accumulate. So if you don?t use much fuel, either keep your storage tanks as full as possible, or better yet, size your tank so that you get it empty every so often.

The best place to buy diesel fuel is from a place that sells a lot of it.

Any vented tank, gas or diesel over time will get water in the fuel through condensation. Ever notice the fuel level in the spring or fall by the moisture on the outside of a tank? That same moisture is on the INSIDE too since the tank is vented. Best way to keep water out, is to keep the tank full. Only fuel that water won't get into unless you put it in during filling is LP gas since they are under pressure. I like diesel, but LP has the advantage far as water problems go..

Last time I looked, farm storage tanks tilted to one end and under that end was a drain. That drain was used to drain off condensed moisture. Since oil floats on water, it was an easy fix.

I add a little Seafoam to the fuel to take out the moisture and clean up the system,must work since I don't have water in fuel problems.I also only buy fuel from name brand stations at the
Auto Diesel pump,figure no fuel company is going to put questionable diesel in the pump supplying fancy cars and pickups.We also file for state and Federal road tax back for off road use.
I have a credit card I use just for off road fuel use so the book keeping is easy.

Mike why in the world you you say that. My life long experience is that is exactly wrong. The big trucks stops that sell thousand of gallons of fuel each week are less likely to have condensation and water. For two reasons first buy so much fuel going thru there just no chance of condensation and then if there is water is is divided into a lot more gallons. I just cannot understand your thinking on that statement. Sure not so from my life long experiences. We have a 12,000 gallon bulk diesel storage tank here on the farm for off road fuel but we buy all the big truck fuel from truck stop for the very reason I have mentioned above, fresher cleaner fuel.

Our JD 4600 has a regular filter that looks like that, but the fuel tank is shaped like a big funnel, holds over 10 gallons. the pipe going to the filter is about 4 inches from the bottom, and right on the bottom is a drain valve that you can put a hose on. A couple of times a year I drain out about 8 ounces, been doing this for 18 years, it's a great system, no fuel problems. I have never seen anything questionable in what I drain out, but then i use a fine screen funnel when filling.

Lots of good answers, but nobody hit the nail on the head. Hot fuel straight from the refinery will have a few molecules of moisture in it which will settle out as the fuel cools. Even oil has the ability to hold moisture just like air.
As others have stated moisture can come through condensation, filling tanks during a rainstorm, cap left off on the transport tanker, etc.
In my opinion, the more fuel run through a truck stop the more water they will have in their tanks from the refinery. Conversely, the less fuel the more water they will have from condensation. You put a tell tale grease on gauging equipment which will turn pink when it contacts water. All fuel facilities drain water regularly. No tanks are water free but the goal is to keep it in the water well at the bottom.
But the crux is moisture is very bad for injection pump lubrication so all diesel engines have multiple water separation methods - trap, bowl, filter, etc. They may never get water in them but they still need to be there just in case. My Cummins has a water in fuel light which has not come on in 300,000 miles. If you are careful you won't need the water trap but you want it there.

Well back in 1982 I got a brand new Chevy truck with the 6.2 diesel. ( biggest POS ever made but that's another story ) These have a drain on the fuel filter. I would buy fuel at the local truck fuel station. I would get lots of junk draining out of this filter when I checked it. Started getting fuel delivered to the house and that solved that issue. So that is why I say that.

Traditional,
There is a wide range of opinions about which additive to use. I will use Lucas because I have about a half gallon and a friend who has Diesels most of his life has had Diesels. That said sea foam may be better.
How can you tell?
If additives remove water it should be easy to tell if it does, just look for water in the sediment bowl.
I've read that Country Mark has better Diesel. Friend who uses lucas claims he gets best mpg using Kroger diesel.
County mark may sell tax exempt fuel.
If I decide on county mark, I'll need to paint gas can and duct tape over gasoline on the cans.
Thanks to all. This old dog needs to go back to school on Diesels.

The only thing I have seen about tax exempt diesel at service stations is say if there is a 20 cent tax on diesel it'll be less than 20 cents cheaper so buying the on road and filing for the tax back you're ahead in the long run.Also my credit card pays 5% back on all fuel purchases so I'm getting 5% off the initial tax too.My wife was an accountant/book keeper in an earlier life(LOL)

That's a good point. My Fords have CAV pumps and they can't tolerate water. As a result there are 2 inline filters between the tank and the pump on
these tractors. My newest Ford is an '88 3910 and the first filter non longer has an element in it. Same size fixture and in the same place, but rather
than having the painted metal filter can it just has a glass cylinder so that you can see if any water is in your fuel. Both filters have drains.

There are no fuel additives to remove water in fuel.I
The only thing they can do is suspend the water more evenly throughout the volume of fuel in the tank.
Allowing the engine to run without trying to burn large slugs of water.

Our favorite place Menards has the lucas fuel conditioner on sale. But on your new Kubota I don?t think you need it. In my Kubota?s I only use Lucas anti gel starting now through the winter for extra measures on top of my fuel suppplier. Power service anti gel was on sale at Menards the other day. I run the Lucas fuel conditioner and the Lucas oil stabilizer in a couple old cat tractors with 6000 and 7400 hours and my combine with 4100 hours. Maybe not necessary but I use it.

I drain the water off the bottom every so often to keep it from getting in the equipment. If the tank doesn't have a drain plug I put one in.
