The TK-240 Portable Fuel Tank Cleaning and Fuel Transfer System is the ideal single piece of support equipment that every diesel-fuel-powered equipment owner needs to assure that the diesel engines they depend on will perform with optimal performance every time the key is turned.
When combined with the XT option package, the TK-180 Portable Fuel tank Cleaning System will provide long term tank cleaning and fuel management benefits.
The TK-240 will provide fuel re-circulating, filtration, polishing and/or handle the transferring of diesel fuel and other light oils in vessels, stand-by generators, trucks, buses, agricultural and heavy equipment.
The TK-240-XT is compact, portable and easy to use. For marine applications, the TK-240 effectively removes water, sludge from the bottom of tanks and transfers waste to the appropriate waste receptacle. But the Portable Tank Cleaning System is also ideal for use on the farm to keep the fuel in equipment tanks that are used seasonally or only occasionally. Small service companies (tree services, landscape maintenance, construction companies and others) also are able to keep equipment running more efficient and get longer life out of filter elements, not to mention fuel system components. The TK 240-XT guarantees Optimal Fuel Quality for Reliable Power at All Times.
Where the Problem Starts
Most problems with diesel engines start in the fuel tank. Stored fuel has always suffered from degradation and microbial contamination, causing problems that are evident from the symptoms of fuel problems long before you realize that the real problem is in the bottom of your fuel tank. When your fuel filters become clogged long before they should, you see smokey exhaust, experience loss of power, and strange odors are coming from your fuel tank, then you need to look to the bottom of your tank. The problem is the fuel. For a complete understanding of the problem, read Understanding Diesel Fuel Problems (.pdf) of the the Guides available to further explain your situation.
Many owners of diesel equipment and diesel repair professionals have heard or experienced the phenomenon where an organic slime, mistakenly identified as algae, is seen floating around in the fuel storage tank and the fuel filters are covered with a black, slimey coating. The actual problem is an infestation of a microbial or fungal organic nature. Water in the bottom of the tank provides the habitat, and the microbes feed off additives in the fuel-water interface. The reproduction process of the microbes throws off a slimey material and produces acids. This slimy material is mistaken as algae (but algae requires sunlight to grow, and not much sunlight gets into fuel tanks). In addition, as diesel fuel degrades with age, and reacts with the acids from the microbial contamination, the asphalt component in solution in the diesel fuel comes out of solution. This makes the fuel appear dark, sometimes black. As the asphaltene components in the fuel clings together, the fuel gets dark and, as the clumps of asphalt gains weight, sinks to the bottom of the tank, mixes with the debris created by the microbes and accumulates as sludge in the tank bottom, sometimes looking like the tank was painted with roofing tar!
Solving Your Fuel Problems
You will see that there are two ways of handling the types of fuel problem described above. Mounting the Magnetic Fuel Conditioner in-line between the tank and primary filter works great. You need to keep the water out of the tank, and periodically use the ALGAE-X additive AFC-705 Dieel Fuel Catalyst, an additive designed to clean the fuel tank. To understand how it works, read In-line Fuel Cleaning. But, as explained in the In-Line Fuel Cleaning Guide, the Magnetic Fuel Conditioner only does its job when the vehicle or equipment is operating and running. So often the equipment that has the problem is only used occasionally, such as seasonally, or, as with backup power service, the fuel is kept for an emergency when the lights go out. So often, you don't know you have a problem until it shows itself when you need the equipment to perform the most. Planning ahead is critical. A Fuel Treatment System is needed long before the fuel is found to be foul, contaminated, degraded, and inefficient. It often is worse as unexpected maintenance and repair expenses result from using the degraded, contaminated fuel, such as fuel injector and fuel pump failure. Read Determining What Fuel Treatment System is Right for You. The most basic system, and most economically priced system, is the TK-240.
Using the Right Equipment
The base TK-240 is equipped to perform circulation of fuel in storage tanks up to 1,000 gallons on a "stand by" basis. For a complete understanding on why fuel circulation is so critical, read Fuel Treatment and Continuing Management. This paper describes large scale fuel treatment, but all of the principals apply to smaller installations and to problems with individual equipment as well.
The TK-240 Portable Tank Cleaning System includes everything you need to circulate the fuel removing heavy debris, treat the fuel with the Magnetic Fuel Conditioner, and filter the fuel. Included in the TK-240 package are hoses, a pre-screen filter to protect the motor from damage, a filter that comes standard with a water block 15 Micron element, and the instruction manual; everything you need to start effectively and efficiently cleaning diesel fuels.

The following five papers will explain how diesel fuel becomes a problem with age, and how our systems will solve these problems. Print them and show them to the Boss!
The TK-240 XT package includes several additional components that make the TK-240 more user friendly and makes it a complete package. Included in the XT package is the optional spill and drip tray that contains any fuel that may splash or leak during hose disconnecting, when the screen is disassembled for cleaning, or when the filter elements need replacement. The tray also provides a handy place to store tools. Also included in the XT package is a special wrench for loosening and tightening the bowl on the filter unit. Most importantly, an 8-oz, bottle of ALGAE-X AFC-705 Diesel Fuel Catalyst is also included.
Using the Right Fuel Additive
The AFC-705 Diesel Fuel Catalyst works "Hand and Glove" with the TK-240 Portable Tank Cleaning System. Although the TK-240 can pump water and sludge from the tank bottom, and then recirculates the fuel repeatedly to gradually polish the fuel, making the diesel fuel "clear and bright" the way diesel fuel with optimal combustibility looks and performs, the debris and organic matter in the tank still sticks to the tank bottom, walls, baffles, and top, and residual water remains on the tank bottom. The AFC-705 Diesel Fuel Catalyst dissolves the debris off the bottom and sides of the tank putting this debris up in suspension in the fuel so that as the fuel circulates through the TK-240, the debris is removed. Also, the AF-705 Diesel Fuel Catalyst has a chemical component that will emulsify the residual water up into the fuel. Then, as the fuel is circulated through a special water block filter element in the filter assembly, the water is captured and the fuel loses the hazy look and becomes clear and bright.
For a complete understanding of the steps involved in polishing diesel fuel, read the Cleaning a Fuel Tank paper. All of our fuel management systems work essentially the same, only on different scales to address different sizes of storage capacity and management requirements, but htis guide explains the process in detail using the TK-240.
Sample Tank Bottom
If a tank has a straight-line access to the bottom of the fuel tank from the fuel fill hole or through another inspection port, a length of PVC or similar material pipe, 1/2 inch in diameter, can be used like a soda straw to sample what is in the bottom of a tank. Cut the pipe to length to allow insertion of the pipe to the bottom while allowing your thumb to cover the exposed end of the pipe. With your thumb over the end, insert the pipe to the bottom of the tank, remove your thumb so what is at the very bottom will rush into the tube to the level of fuel in the tank. Again place your thumb over the end of the pipe and extract the pipe, maintaining the liquid and other materials inside the tube. Place an empty clear plastic 2 liter soft drink bottle upright in the bottom of a empty 5-gallon bucket. Direct the end of the tube into the drink bottle (any spilled liquid will be caught inside the five gallon bucket). Perform this action several times. Allow the contents of the bottle to settle (ideally overnight) and inspect the materials in the bottom of the drink bottle. Any debris or water should be apparent.
If your tank is larger and using a tube to same fuel from the bottom of the tank is not possible, you can use a Tank Sample (TS) Fluid Sampler. You can take 4 oz., 8 oz, or 16 oz. samples using the AXI Tank Sampler or you can use a hand-held Sample Pump (at bottom of the AXI Tank Sampler page) to remove a sample, as described on the Tank Sampler page.
Ongoing Vigilance in Keeping Water Out of the Tank
Water in the tank is often at the heart of having fuel problems. Water can get into the tank with a load of fuel, it can be from rain water entering the tank when the cap is not replaced or is left loose, and it can be drawn in as fuel is used from a tank as moisture in the air condenses and accumulates.
In some climates, you should check for water in your tank each month. In some locations where fuel quality from the supplier is suspect, it is smart to use Kolor Kut Water Finding Paste, or a similar product, to check for water after each time you tank on fuel. Water may be mixed in with the fuel when it is put into your tank. If possible, allow 48 hours for the fuel to settle and the water to separate from the fuel and accumulate on the bottom of the tank. Then place some Kolor Kut Water Finding Paste on the bottom 4 to 6 inches of a rod or length of rigid PVC tubing and stick it to the bottom of the tank. The paste will change colors if it touches water and indicate if any water, and how much water, has accumulated in the bottom of your tank.
If water in the tank bottom is a problem, consider taking one further step to preventing problems in the future by utilizing the Water Eliminator. This handy product contains crystals that absorb water, but not fuel, and contains the water until removal and proper disposal, minimizing the chance to water being a habitat for future microbial contamination and for water to be picked up in the fuel and causing damage to engine components. Visit the Water Eliminator pages for more information.
Fuel Quality Management - The Key to Engine Reliability & Performance
The TK-240 is the perfect addition to the "tool box" of technicians, maintenance facilities, garages, boat owners and service vehicles. It is an ideal way to provide fuel maintenance and tank cleaning services. May be used for lightweight lube oils, anti-freeze, water or as a bilge pump. (do not use with gasoline)
ALGAE-X® TK Systems are designed around a self priming 240 GPH (910 l/hr) nickel plated brass gear pump. The quality filtration components are connected with corrosion resistant stainless steel plumbing. Filter elements are available in two choices, 10 Micron particulate (TK-081) or 15 Micron water block / particulate removal (TK-082). A pressure gauge is installed on the filter to ensure optimal filter usage. Fuel can also be polished without using any consumables by utilizing cleanable wire mesh filter cartridges (TK-083 / TK-084). The wire mesh cartridges are recommended for use when a known contamination problem exists to remove the "big pieces" of debris. After no clumps and chunks are visible in the clear suction hose, switch to the fine filter elements.
The use of ALGAE-X® Fuel Catalyst AFC-705 is an essential part of any tank cleaning procedure, to more rapidly and efficiently decontaminate and clean the entire fuel system. AFC-705 removes sludge, slime and bio-fouling from tank walls and baffles that can’t be reached with the suction line. AFC-705 is a full spectrum fuel additive containing combustion catalyst, surfactant, detergent, dispersant, corrosion inhibitor, lubricity enhancers and fuel stabilizer that eliminates the need for expensive toxic biocides.
