The 12 inch (30.48 cm) Water Eliminator lies on the tank bottom and absorbs accumulated water


Water Eliminator crystals are water specific and will swell many times their weight in water. Water specific means they will only absorb the water in your tank and will not absorb or adversely affect gasoline, diesel fuel, fuel oil, JP5 or hydraulic oil.

Water Eliminator Crystals

Thread lanyard loop through hole in the top of the cap, and run snap hook through loop. Pull tight.

Attach the snap hook to the safety retention chain on the fuel cap. Slowley lower cartridge until it rests flat on the bottom of the tank. Check the cartridge in 6 to 12 hours to see if it has filled with water. If it is full replace with a new cartridge. If not, lower it back into the tank and check with each fuel fillup.

New High Pressure Common Rail (HPCR) injection system designs incorporated into todays diesel engines require clean fuel to operate at full potential. The engines are designed to be more efficient, but cannot maintain optimal performance and reliability using degraded or contaminated fuel. When an engine is providing less than peak performance or engine maintenance reveals clogged fuel filters, excessive exhaust smoke, or other symptoms of a performance problem, the problem typically lies in fuel quality.

Fuel degradation is a natural process that causes the formation of sediment, sludge, and acids in the fuel. Historically, diesel fuel would remain stable for years and engine performance problems that could be traced to the diesel fuel were few. Many diesel mechanics did not even consider fuel quality or contamination issues when diagnosing performance problems or component failures. But fuel related problems have become much more common as crude oil refining processes changed to accomodate the government imposed adoption of Ultra Low Sulfur Diesel (ULSD) in the last decade. Users of bio-fuels suffer from an even more dramatic increase in fuel re-polymerization that causes rampant filter plugging, fuel injector failures, and an overall reduction in stored fuel shelf life. With today's fuels, the degradation process of stored fuel can reach the problem stage in as little as six months, and is further accelerated by the extreme pressure of HPCR engines, temperature change, water, and microbial contamination.

A critical part of a Fuel Management Program to extend diesel engine life and assure peak performance is as simple as keeping water out of the diesel fuel. Water is a common problem, and many believe an inevitable problem. But simple and inexpensive steps taken to assure that water is not allowed to collect in the fuel pays great dividends.

Simple steps, like not leaving the fuel cap off a storage tank, or periodically checking the fuel tank with a rod and Kolor Kut Water Finding Paste will go a long way to keeping the water out. But water gets into the tank in many ways. Sometimes it is introduced at your local filling station or by your fuel distributor when water is loaded from the central storage tanks when the tanks are low or shortly after the tanks are filled, and stirred up water is pumped into the tanker truck. But also it is introduced while you drive. As a tank of fuel is used, the tank pulls air through a vent. Moisture in the air condenses on the sides of the tank and, over time, accumulates in the tank bottom. If you have equipmnet that is used seasonally or intermittently, you are exposed to the problems of water accumulation in fuel tanks.

This water can be a problem in numerous respects. Water freezes in the winter. It can accumulate to the point where the fuel line to the engine picks up water and causes engine component failure. Water is the habitat of microbial and fungal contamination, and, in time, can cause filters to clog, engines to smoke, and acids from the process to degrade tanks and engine components (i.e.: injectors).

The Water Eliminator

If you store fuel for use in equipment, operate a boat, RV, farming or construction equipment, you need the Water Eliminator®, the most cost effective way to remove water from Gasoline, Diesel Fuel, Fuel Oil, Kerosene or Hydraulic Fluid.

The Water Eliminator® presents an easy and economical solution for removing water from tanks used to store fuel, whether the tanks are installed on equipment, fuel stored in day tanks to meet surge demand, or larger storage tanks. Maintaining fuel free from water reduces the potential for microbial contamination and accumulation of sludge in tanks. The Water Eliminator® is available in various sizes for engine service, fuel transfer tanks, home heating oil tanks, and large fuel storage tanks.

The Water Eliminator captures water directly from the fuel, or oil in the tank. The crystals contained inside the Water Eliminator are water specific and will swell encapsulating the water until the cartridge is full. The Water Eliminator® helps to prevent service problems related to water contamination including: Plugged Fuel Filters, Fuel Line Freeze-up, Damaged Fuel Pumps and Injectors, Corrosion, Damaged Injectors, Growth of Microbial Contamination, Loss of Power, Corrosion, and Down Time.

Water EliminatorWhen used in mobil equipment, check your Water Eliminator® at each fuel stop. If the unit is empty, your tank is water free. Leave it in place until nearly full, then discard in a proper receptacle and replace it with a new one. (Disposal in accordance with local and federal regulations.)

How the Water Eliminator Works

The units contain a water adsorbent polymer that captures free or emulsified water on contact when placed in the fuel tank.

WE-12 Duty Water Eliminator

The WE-12 Water Eliminator package contains one 12 inch long cartridge (not including the hole on one end for securing the lanyard) and two lengths of stainless steel lanyards, each 39 inches (one meter) in length. It is ideal for use in heavy duty trucks with saddle tanks, construction equipment, farm equipment, generators, marine applications, fuel storage tanks, home heating oil tanks and fuel transfer tanks.

Requires a 1.85" (4.7cm) or greater tank opening. Fuel filler pipe must allow direct access to the bottom of the tank. Unit is not designed to be withdrawn around bends. For tanks that are greater than 72" (182.88cm) in depth an additional lanyard will be required.

Each lanyard has a loop on one end and a snap hook on the other. One lanyard is required for tanks up to 36 inches in height. Loop the lanyard to the WE-12 as shown below and connect the other end, using the snap hook, to the safety retention chain on the fuel cap. For tanks up to 78 inches in height, use the second lanyard to tether the WE-12 Water Eliminator. For tanks larger than 78 inches in height, use additional lanyards. The WE-12 Water Eliminator must lie flat on the bottom of the tank. A rod inside the WE-12 Water Eliminator provides weight and assures that the unit will stay on the bottom of the tank.

Storage Tank Water Eliminator

The WE-S31 Storage Water Eliminator® for large storage tanks (1,000 gallons or more) has a 31.25 inch by 3.5 inch containment tube fabricated from 304 stainless steel that uses disposable inserts. Its lanyard is a 16 foot long electro-zinc plated steel chain and includes an eyebolt with rubber seal to attach to tank fill cap.WE-S31 Water Eliminator Each insert is 3.25 inches in diameter and 30 inches long and will remove 1 gallon of water. The simple "Twist to Open" and "Twist to Close"e; operation requires no tools for the replacement of the cartridge. When first installing the unit on an older storage tank it may be necessary to use several cartridges to remove the water. For larger tanks, several Storage Water Eliminators® may be linked together to form a chain. If there is a known accumulation of water and sludge in the tank, it is recommended that the tank bottom be pumped first prior to installation of the WE-S31 Storage Water Eliminator®. Check periodically, and if the insert is more than three-quarters full, the insert should be changed. The replacement insert for the WE-S31 is Part No. WE-B31.

Water Eliminator Cautions

For optimal results we recommend to not use additives which contain water dispersants. The Water Eliminators® insert should be removed from the tank in less than sixty days. The manufacturer is not liable for damages resulting from improper use of the product.

Water Eliminators are available in the following sizes:

  • WE-12 -- 12" units

  • WE-S31 -- Storage Tank Model

  • WE-B31 -- Refill Storage Tank Model
