Frequently Asked
Questions

The fuel flow first enters the Fuel Conditioner immediately upon exiting the fuel pump. Operating on the principal of induction on the process of combining kinetic and magnetic energy to influence the behavior of electrons, the Fuel Conditioner provides a powerful magnetic field and the flow of fuel provides the kinetic energy.

LG-X 500 Fuel ConditionerAs fuel deteriorates, clusters of fuel components break down and residue begins to accumulate, resulting in dark, hazy fuel with poor combustibility. This residue is composed primarily of asphalt components of the crude oil from which diesel fuel is refined that have fallen out of solution.  The fuel becomes dark as the asphaltenes agglomerate and gain weight. The increase in size and mass of the fuel breakdown products lead to clogged filters and the build up of tank sludge.

Accumulation of water in the fuel tank provides habitat for bacterial and microbes brought into the tank through the breather vent or with fuel. As this microbial growth grows and reproduces, a bio-film accumulates and attaches to the tank walls and baffles of the fuel tank and may be seen floating in the fuel (and sometimes referred to mistakenly as “algae”).

This accumulation of bio-mass and fuel breakdown clogs filters, adversely impacts combustion efficiency, produces dark smoke from the exhaust, form acids that degrade injectors and fuel pumps, and adversely impacts performance.  Eventually fouled diesel fuel will clog fuel lines and ruin your equipment.

The Fuel Conditioner dissolves the clusters, stabilizes the fuel, and eliminates tank sludge. The results are Clear & Bright Fuel, improved filterability, optimal combustion and clean fuel systems. It also adversely impacts the reproduction process of the microbes and prevents further growth (see the article “Why Bacteria Hate Magnets“, allowing continuing use of the fuel to eliminate the microbes. The process of how the Fuel Conditioner makes clear, bright and more combustible fuel as well as restoring degraded fuel and eliminating the effects of microbial contamination is compelling. As the Fuel Conditioner does not filter the fuel, but treats it as it passes through the unit, there is seldom any reason to suspect that a restriction is in the Fuel Conditioner. But you can remove the face plate, remove the magnet and wipe it off with a shop rag and replace the magnet and face plate. A spare parts kit for the Fuel Conditioner includes a new face panel O-Ring and replacement screws to fasten the face plate.

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, PEX 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 of the tank 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 recover fuel, water or other debris 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.

You can also use the FS 100 Hand Pump to pull fuel through a length of tubing and into a Sample Bottle.  Instructions for using the Hand Pump is on the Fuel Sampling Devices web page.

The following is the five stage fuel system of the typical Separ SWK-2000 Fuel Filter/Water Separator:

  • Stage 1: From the inlet port, fuel flows through the interior vane system which imparts a circular motion to the fuel.Separ SWK 2000 Filter Cutaway
  • Stage 2: Still in circular motion fuel reaches the bowl section where, due to this centrifugal motion water droplets and heavier particles are forced to the wall of the bowl eventually settling in the bottom of the bowl.
  • Stage 3: In this stage the fuel has to pass the vane system positioned on the “outside” of the central housing. Due to differing length of the vanes and the twofold rapid change of fuel flow direction, smaller water droplets and finer particles will settle on the vanes. These settlements will agglomerate and when heavy enough fall to the bottom of the bowl. Already at this point the major portion of any contaminates in the fuel have been separated.
  • Stage 4: Just below the filter element the flow area of the filter is increased significantly thus reducing the fuel flow rate. This calming effect allows even smaller water droplets and particulate to fall out settling on the inner surfaces of the housing forming larger droplets which eventually fall into the bottom of the bowl by gravity. Due to the before described pre-separation process the major portion of water and particulate present in the fuel will be in the bowl or on the inner surfaces of the filter thus greatly extending the filter element life.
  • Stage 5: The final filtration of the remaining water and particulates still contained in the fuel will be effected by a replaceable filter element. These filter elements are produced from a special filter media and are available in different pore sizes. The clean fuel leaves the filter via one of the two outlet ports.

A Vacuum Gauge is provided on the top lid of the Separ Fuel Filter/Water Separator to allow for visual monitoring of Vacuum. When the Vacuum reading increases, indicating that the replaceable filter element has reached its capacity for holding particulate material, you know the filter needs changing. No more guessing or changing the filter too soon.

It is not unusual that a Fuel Polishing and Tank Cleaning System is installed at a level above the fuel that is to be maintained, especially in underground tanks or base (or “belly”) tanks of generators.  How do you maintain the prime on the pump in such an installation?

Foot ValveFoot Valves are handy little devices that can be installed at the end of a pipe line in a suction lift application.  They function as a check valve to maintain the prime and also have a strainer affixed to the open end. The check valve is spring assisted.  When the pump is turned on, the suction opens the valve and the fluid flows. When the pump stops, the valve responds again by closing. This stops fluid from draining out of the pump column and causing the pump to lose prime every time it turns off.  

The strainer also keeps debris from becoming lodged in the foot valve. This would result in the valve being stuck in the open position, and all the fluid draining from the pump column. That nullifies the point of the foot valve! Some foot valves offer tight mesh, others offer a wider grid strainer.

Any installation of a Fuel Maintenance System dedicated to the cleaning and conditioning of fuel in one or multiple tanks would benefit from the inclusion of a foot valve.  The efficiency of a system that is programmed to operate on a periodic basis would suffer if an operator must prime the pump each time a tank is due for maintenance.

The Multi-Port Flowpath Actuated Valve System is available to operate in unison with several of the FPS Fuel Polishing Systems.  Each MP-VS Valve Set includes two (2) Solenoid Valves (one for the suction and one for the discharge line) and one Foot Vale to be installed on the end of the suction pipe.  One valve set is typically installed in each partitioned section of the base tank.

Clogged Filters, Dirty Tanks?

FPS Series Systems Clean Fuel

Frequent Filter changes and incurring the expense and inconvenience of cleaning fuel tanks have become acceptable periodic maintenance instead of a warning signal for engine failure. Filter elements should last a thousand hours or more, and injectors some 15,000 hours. However, since diesel fuel is inherently unstable, solids begin to form and the accumulating tank sludge will eventually clog your filters, ruin your injectors and cause engines to smoke.

Fuels and oils are susceptible to natural deterioration, like any other organic fluid. Oxidation, chemical incompatibility, water and microbial infestation all contribute to the process of polymerization and stratification of diesel fuel and other hydrocarbons. This results in poor Fuel Quality, and the formation of tank sludge, bio film and acids. These by-products of the process of fuel breakdown cause clogged filters, corroded injectors, pumps and tanks, incomplete combustion (evident from black smoke, caused by un-burned fuel, from exhaust), carbon build-up on engine components, and loss of power. As these problems build on each other, these individual symptoms of bad fuel ultimately lead to complete engine failure.

Filters, separators, and centrifuges remove particles and free water from fuel. Biocides, commonly recommended by many mechanics to cure the ills of “algae” in fuel tanks, are really less than effective in the long term control of microbial activity. Neither, however, eliminates fuel instability or sludge buildup in tanks. Biocide treatments aggravate filtration problems by turning bio-sludge into solids. Removal of fuel tanks for cleaning with high pressure washers or steam (a favorite recommendation of equipment dealers) is expensive, takes equipment out-of-service, necessitates the removal and disposal of fuel from tanks, and is likewise ineffective and does not provide a long term solution.

A study by the University of Idaho determined that there could be as much as a 26% degradation in diesel fuel after just 28 days of storage.

Diesel Fuel is Inherently Unstable

Diesel engines continuously return fuel not used for combustion back to the tank. The repeated exposure to the heat and pressure of the injection system accelerates this breakdown of fuel quality. Fuel quality and fuel chemistry is affected by transportation, storage tank conditions as well as time, and factors such as oxidation, water in the fuel, microbial contamination (contributing to acid formation), and incompatibility of fuel additive packages with after-market additives, etc. This toxic combination negatively impacts: (i) the filterability of the fuel through filters that become clogged; and (ii) causes a dramatic increase in the size of the fuel droplets emitted from the fuel injector into the combustion chamber. The degraded condition of the fuel, when combined with the injector degradation that occurs over time from the use of the degraded fuel, result in fuel not being completely burned in the combustion chamber and formation of carbon deposits on internal engine components, all evidenced by a noticeable increase in smoke from the exhaust, loss of power, and an increase in fuel consumption. (See “Diesel Fuel & Injector Failures” for additional information)

Automated Primary Filter Fuel / Water Separator Water Removal with the FPS Series OPT-TSC / AWD

The Automatic Water Drain (AWD) System is comprised of a DC gear pump, solenoid shut off valve, and a strainer that will automatically remove water collected in the sump or bowl of the water / fuel separator, typically the Primary Filter in the STS Series or select FPS Series (those configured with AC power). When the system detects high water levels, the pump is alerted and the water is deposited into a 15 gallon capacity waste water drum. When the water recedes to a lower level, the pump stops.

The waste water drum has a float switch to prevent operation if the waste drum reaches its holding capacity. Inter-connectivity with the upgraded main System TSC-7000 Touch Screen Controller, that offers Modbus, TCP/IP, LAN & Internet Connectity with E-Mail & SMS Maintenance Alerts, will shut down operation and provide an alert that the System requires operator attention. This requirement necessitates the upgrade of controllers on the STS 6000 Series and the FPS Series Systems to include the TSC-7000 Touch Screen Controller.

Fuel Storage in Base Tanks

The proliferation of back-up power generator systems in the past decade serving first responders, data centers, hospital facilities, municipal water and sewer facilities and other infrastructure has been dramatic. The most common configuration is the placing of a diesel engine and generator, within an enclosure, situated on top of a metal structural fuel tank containing structural supports for the engine and enclosure. Cleaning such a fuel tank can be challenging as the support structure creates compartments within the base or “belly” tank that makes it nearly impossible to reach all areas of water and debris accumulation.

The Multi-Port Fuel Flow System that utilizes any one of the FPS SX-F, MX-F or LX-F Compact Fuel Polishing System is uniquely designed to use a suction and discharge point, controlled by a solenoid valve, that is installed in each chamber of the base tank enabling the cleaning of the entire tank while conditioning and stabilizing the fuel. Review the Multi-Port Fuel Flow System if you are managing the fuel of a generator that uses a base tank.
