How does water get in fuel filter?
Additional water can enter fuel systems through an open fill port, a defective tank, or an open drum during rain. Or it can simply be transferred from another water contaminated tank. The presence of water in diesel fuel systems causes a variety of problems.
Water is commonly found in diesel fuel due to many factors including condensation in fuel tanks, improper handling and environmental conditions. To minimise the damaging effects, water should be removed from diesel fuel prior to the final stages of solid particulate filtration.
Some water will also drip down from the exhaust due to condensation. The fuel filter prevents water from getting into the engine to a certain extent. However, once the water content gets stuck inside the filter body, the filtration efficiency decreases. Hence, it is necessary to replace the fuel filter.

Some filters, especially found on diesel engines, are of a bowl-like design which collect water in the bottom (as water has a higher density than diesel). The water can then be drained off by opening a valve in the bottom of the bowl and letting it run out, until the bowl contains only diesel.
Heet is the industry standard if you need an additive to remove the water from your gas tank. Not only is ISO-HEET a gas anti-freeze, but it can remove up to 5x the water as other additives. Easy to use and can be used with 2 cycle engines, gas or diesel.
The short answer is yes: putting water in your fuel tank will most certainly destroy, or at least severely damage your engine.
Water can cause corrosion inside your fuel system and injectors and keep them from monitoring your fuel delivery rate properly. If left long enough, your injectors can eventually fail altogether, meaning your car won't start at all.
What are the symptoms of water in the gas tank? A good indicator is a sudden change in the performance of your vehicle. You try to accelerate and the car hesitates or sputters consistently. You try to get up to highway speeds and the car just doesn't want to cooperate.
Pull the engine oil and transmission fluid dipsticks and differential plug. If the fluid appears milky, diluted, is no longer its original color or is beige in color, then it is likely the pans contain water.
How often should you drain your fuel water separator?
If you use gas w/ ethanol, you are bound to get some water in your fuel. Don't know what type of engine you have but Yamaha recommends every 50 hours. I agree with Bunger79 until you consistantly have a clean filter, then I would go to 100 hours.
How Long Does It Take For Heet To Remove Water? moisture removal usually takes between 15 and 20 minutes with HEET. There are other factors, however, that can impact this amount of time, such as the temperature.
- A loss of RPM and power in the machine.
- Rough starting or erratic idling.
- Trouble or a lag in acceleration when stepping on the pedal.
- Abnormal exhaust such as white smoke.
To get water out of your diesel fuel, you need to drain or pump as much water out of your fuel tank as possible. Remember to use a siphon hose long enough to reach the bottom of your tank. Add the proper amount of Diesel 911 (or your preferred diesel additive) to your fuel tank.

If your car is on idle and you notice it sputtering, surging, or even stalling out, then it's possible that your car has contaminated fuel. Similarly, if it's difficult for you to start your car–or it seems to start and then die down consistently, then your fuel might contain water in it.
