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.

Gasoline suffers from a similar problem. Separation of water from gasoline containing ethenol is well documented and can cause serious damage to gasoline engines, whether in automobiles, marine, or small engine applications.

A critical part of a Fuel Management Program to extend diesel and gaoline engine life and assure peak performance is as simple as keeping water out of the 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 of a fuel tank. But water gets into a fuel 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 fuel level in those tanks is low or the load out is done shortly after the tanks are filled, thereby stirring up water in the tank bottom. The water that is stirred up is pumped into the tanker truck, and delivered to the service tank with the fuel.

But also water is introduced to your fuel tank while you drive. As a tank of fuel is used, the tank pulls air into the tank through a vent to replace the space in the tank prevously occupied by the fuel. 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, a particular problem where the tank experiences considerable movement, such as in marine applications, construction, farming, and off road applications. 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 gasonline or diesel fuel for use in equipment, operate a boat, RV, backup power generators, 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 Eliminator

When 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 Water Eliminator

The WE-12 Water Eliminator package contains one 12 inch long (not including the hole on one end for securing the lanyard) cartridge 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.

A 1.85" (4.7cm) or greater tank opening is required. The 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.

The WE-12 Water Eliminator has a cylindrical injection molded nylon "skeleton" with several longitudinal and circumferential ribs that are ultrasonically welded and which surrounds a filter screen that contains the absorptive crystals. This construction retains its shape after the crystals have absorbed its full capacity of water without deforming or impeding removal from the tank opening. Beware competing products that utilize a fiber or cloth bag with the crystals secured inside. There are often sharp edges on the inside of the fuel tank or on the chain that secures the fuel cap that can rip the fiber and spill the crystals into the bottom of the tank. Also, the flexible bag does not constrain the expanding crystals and can sometimes expand to a circumference larger that the tank opening making removal difficult to impossible without ripping the cloth bag.

Each Water Eliminator includes two lanyards with 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.

Water Eliminator Cautions

For optimal results we recommend to not use additives which contain water dispersants when using the Water Eliminator®. The Water Eliminator® 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.
