Generators are a lifesaver; Whether we talk about hospitals, manufacturing units, data centers, or other industrial estates, emergency backup generators are the backbone of almost every small and big industry across the globe. But, the only problem? These backup power suppliers are entirely dependent on the quality of the fuel, and the generator can experience unnecessary outages if the engine becomes jammed. However, the good part is that we will inform you about the common issues with diesel fuel polishing systems and how to address them professionally.

In this blog, we will explain how your generator can start to malfunction, identify the signs to look for, and guide you on how to repair them. Keep reading to learn more about it.

However, first, let us revisit our understanding…

What is a Diesel Fuel Polishing System?

Now, as you know, a diesel fuel polishing system is a setup to remove water, sludge, microbial growth and solid contaminants from stored diesel fuel. It circulates the fuel through filters, water separators and sometimes coalescers to ensure long-term integrity of the fuel. This system uses fuel suction from the storage tank, pre-filters the fuel to remove large particulates and removes moisture from the water. Once done, the Fine filtration traps the microbes and acceptable debris. After this process is maintained correctly, the polished fuel returns to the tank to power the engine.

Now, what are the signs your diesel fuel polishing system needs repair?

If you maintain the fuel polishing system for diesel generators on time, you may not have to deal with generators that can be really expensive to repair. But if maintenance is out of the book, then you must look out for the following key signs that mean your generator needs immediate repair or expert supervision:

  1. Alarm or Shutdown Signals
    When you invest in advanced systems offered by Njord Filtration, it comes with trigger alarms for high filter pressure or water levels. If you notice frequent shutdowns, it may indicate that your filters are clogged.

  2. Visible Sludge in Tanks
    Keep checking for floating particles, black slime microbial growth or sediment buildup and remove them before they start to spread and worsen the situation.

  3. Generator Performance Issues
    Look out for significant signs, such as hard starting, misfiring, or black smoke, while the generator is operating. This may be a sign of dirty or water-laden fuel in the power engine.

  4. High Filter Replacement Rate
    If you're replacing filters more often than usual, it indicates an excess of contaminants in the system.

  5. Cloudy or Smelly Diesel Fuel
    Diesel should be clear with a mild odor, so if you notice dark, cloudy or foul-smelling fuel, it could directly indicate fuel contamination.


Common Diesel Fuel Polishing Systems Issues and How to Fix Them?

Now, if you need to troubleshoot diesel fuel polishing systems in emergency backup generators, then here are the common issues with diesel fuel polishing systems, with expert instructions on how to fix them:

  1. Water Buildup
    Water Buildup is caused by Condensation inside tanks. To fix it, you need to drain the water separator regularly. Then use water-detecting paste for regular checks. Finally, consider upgrading to an automated water sensor if you think it can notify you during higher-risk conditions.

  2. Clogged Filters
    Clogged filters are often caused by excessive contamination or inadequate maintenance. But it's easy to fix if you follow the instructions correctly. So all you need to do is shut off the system and replace the clogged filter. Use high-efficiency filters rated for your fuel type and monitor the pressure gauges to detect clogging early.

  3. Pump Failure
    Pump Failure is caused by constant overheating, wear and tear or airlocks. To fix it, check the power supply and motor wiring first. Once done, bleed air from the pump, and you're good to go!

Step-by-step guide to resolving diesel fuel polishing system failures

If your fuel polishing system isn't working to its full potential, follow these steps to troubleshoot:

Step 1: Visual Inspection

First, check for fuel leaks, loose wires or damaged parts. Make sure the unit is powered on and the control panel is functioning correctly.

Step 2: Check Fuel

Next, check the fuel. Look for colour, clarity and smell. You can also use a fuel sampler to collect fuel from the bottom of the tank for laboratory testing.

Step 3: Inspect and Replace Filters

For the next step, turn off the system, remove the filters and replace both pre-filters and fine filters. Record the pressure differential to track future performance. That way, you can take better care of the filters and manage them before they get damaged.

Step 4: Drain Water Traps

Now, empty all water traps manually if your system doesn't have an auto-drain feature. Then wipe out the growth of microorganisms around the fuel tank.

Step 5: Test Pump Operation

Next, test the pump operation by turning on the system and checking the pump pressure and flow rate. If the flow is low or inconsistent, check for faulty components.

Step 6: Clean the Tank

Once the major tasks are done, check if contamination persists. If yes, then you need to do a complete tank cleaning. Reach out to experts for better services.

Step 7: Run a Test Cycle

Finally, after maintenance, just run a complete polishing cycle. And, do not forget to monitor system readings and check that the fuel returns are clean and dry.

Bottom Line

Now that you know the common issues with diesel fuel polishing systems and how to fix them, you can worry a little less about the power backup not offering its best performance.

Fuel Maintenance Systems: Protecting Your Investment and Reducing Downtime

Fuel Maintenance Systems: Protecting Your Investment and Reducing Downtime

If you use machines that run on diesel fuel—like generators, trucks, or big industrial equipment—you already know  maintaining uninterrupted equipment operation is essential in diesel-reliant industries. But did you know that dirty or old fuel can quietly damage your machines, even when they're just sitting still?

Fuel maintenance systems offer a proactive solution to mitigate equipment risks caused by fuel degradation. They're not something most people think about every day, but they're one of the smartest ways to protect your equipment and avoid unexpected breakdowns.

What do fuel maintenance systems do, and how do they help your business? Find out here.

Diesel Fuel degradation Over Time 

The obvious thing about diesel fuel is that it doesn't stay fresh for life. When it sits in storage tanks too long, it can start to go bad. Here's what happens:

  • Water gets in through air or condensation.
  • Bacteria grow in the water inside the tank.
  • Dirt and sludge build-up at the bottom of the tank.
  • The fuel starts to break down and become less useful.

If you use this contaminated fuel in your machine, it can clog filters, damage engine parts, and even stop the engine from starting. That can impact especially during emergencies when you really need your generator to work.

Definition and Functions of a Fuel Maintenance System

A fuel maintenance system is designed to help clean the fuel and remove pollutants. It is like a cleaning and care system for your fuel tank.

These systems are usually installed on or near your fuel storage tank and work automatically. They clean the fuel regularly—even when you're not using it.

Key things a fuel maintenance system does:

  • Filters out dirt and sludge
  • Removes water from the tank
  • Circulates fuel so it doesn't sit still too long
  • Keeps fuel fresh and ready to use

It's like giving your fuel a regular checkup so it stays in good working condition when you need it.

Who Needs a Fuel Maintenance System?

If you store diesel fuel for more than a few weeks, you better rely on the fuel maintenance system.

This is a smart choice for

Hospitals and data centers with backup generators

  • Construction companies with large machines
  • Farms that use diesel-powered equipment
  • Factories or warehouses that use fuel-powered machines
  • Anyone who stores diesel for backup or regular use

Even if you only use your generator once or twice a year, keeping the fuel clean matters. A generator won't make any sense during a power outage if it won't start because of dirty fuel.

The Risk of Neglecting Fuel Maintenance

Here's what can happen if you don't take care of your fuel:

  • Engines might not start
  • Fuel filters get clogged
  • Parts wear out faster
  • Expensive repairs may be needed
  • Critical systems may fail during emergencies

Most of these problems occur without warning, so waiting until something breaks is not a good plan.

Benefits of Using a Fuel Maintenance System

  1. Clean fuel means fewer breakdowns and less money spent on fixing equipment.

  2. Whether it's a generator or heavy machinery, clean fuel is more likely to make your equipment run well.

  3. Downtime means lost time and money. Fuel maintenance systems help prevent surprise problems that shut down your work.

  4. Engines that run on clean fuel last longer and perform better.

  5. You don't have to worry about your backup systems failing when you need them most.

Why Fuel Maintenance Make Sense?

Most people do not have time to do fuel maintenance themselves. That's why many companies choose to hire experts who handle everything for them.

With a professional fuel maintenance service you get:

  • Regular fuel cleaning and inspections
  • Help spotting problems before they get worse
  • Fewer breakdowns and repairs
  • Priority support when issues happen

It's a smart way to protect your business without adding more to your plate.
