For high performance and longer fuel system life in diesel engines, it is crucial that fuel is free from contaminants, especially when using new ULSD fuels and biodiesel blends.

Cummins Filtration offers a first line of defense at the fuel storage tank to ensure clean fuel reaches the engine system of your equipment. High performance Fleetguard fuel island filters offer superior protection plus a troubleshooting diagnostic tool that allows for longer service intervals.

Fuel producers supply fuel to businesses at a predetermined cleanliness level yet the processes and equipment used to hold and transfer bulk fuel are often not maintained at an ideal level. This can contribute to a large amount of contamination entering the fuel supply chain. Fleetguard fuel island filters precondition the fuel to a level the onboard fuel systems can manage.

Benefits of Fleetguard fuel island filters:

  • Better fuel performance
  • Increased fuel system life – eliminates contaminants before fuel enters the system 
  • Higher fuel economy with cleaner fuel
  • Longer service intervals – on-board diagnostics shows true condition of filter performance
  • Reliability and versatility
  • Dependable media performance, including StrataPore technology™
  • Synthetic media for finer filtration, plus a wide range of micron ratings
  • Differential Pressure Gauge (DPG) retrofits most existing fuel filter heads
  • Low maintenance and easy serviceability
  • Eliminates maintenance guesswork – DPG indicates when filter is plugging and needs change
  • Reduces maintenance costs


  • Mobile service
  • Overhead fuel tank
  • Stationary fuel tank
  • Marina fuel island

On-board Fuel Diagnosis

Fleetguard fuel island filters can be used with a range of filter heads that incorporate a DPG to reduce maintenance time and costs. The DPG closely monitors filter performance and signals when it’s time to change the filter.


How does Fleetguard fuel filtration save me money?

Fleetguard fuel products help you achieve the lowest total cost of ownership by meeting or exceeding OE performance requirements. Fleetguard fuel products provide the latest protection technology for your fuel system.

What is the most important factor to know about a fuel filter?

The efficiency to deliver fuel at the cleanliness level specified by the fuel injection system manufacturer (i.e. you need details such as 98.7% efficient at 5 microns).
How will I know I have a fuel issue before I experience fuel system damage/failure?

Indications of fuel problems will be: 1) premature filter plugging which could be evidence of microbial growth in the fuel 2) frequent need to drain water from fuel/water separators which could indicate issues with fuel storage or equipment fuel tanks 3) unusual fuel colour or odour which could indicate improper use of on or off-highway fuel or microbial growth or excessive heat and oxidation resulting in darker fuel colour

For Remote Mount Processors, what does Fleetguard have available?

Fleetguard offers the following fuel processors: Diesel Pro for light commercial applications – flows up to 5.7 litres per minute (90GPH), Fuel Pro for heavy duty applications – flows up to 11.4 litres per minute (180GPH), Sea Pro for medium to high horsepower marine applications – flows up to 68 litres per minute (1080GPH) and Industrial Pro for extreme duty high horsepower mining applications – flows up to 75.7 litres per minute (1200GPH).

What is FIE?

Fuel Injection Equipment represents the entire fuel system including fuel supply plumbing, supply pumps, high pressure pumps, common rail hardware, injectors and return lines.

What is ISO 4406 and what does it measure?

It is the International Organisation for Standardisation measurement methodology for particle counts in fluids at particle sizes >4, >6 and >14 micron-C. The particle counts are typically specified in units of particles per 100 ml of fluid.

What is ISO 12/9/6?

The display of the terminology "ISO 12/9/6" is the proper means of communicating fluid particle contamination as per the ISO 4406 fluid cleanliness methodology. The ISO 12/9/6 is an example of the fuel cleanliness level specified by some FIE manufacturers and corresponds to particle counts per 100 ml of 4000 at >4 micron-C, 500 at >6 micron-C and 64 at >14 micron-C.

What is a micron?

A micron is a thousandth of a millimetre or a millionth of a metre or .000039 of an inch. Micron is the unit of measure used to determinate the size of particles in a fluid which are filtered out by the filter.

What is the difference between Absolute and Nominal micron rating?

Micron rating is the size of particles which are filtered out by filters at a certain efficiency. When this efficiency is at least 98.6%, we speak about absolute micron rating/filtration. Nominal micron rating is just a commercial trick for all efficiencies lower than 98.6%, meaning that for the same micron rating (for example 10 µ) in the case of nominal rating, not all particles will be captured in the filter as in the case of absolute micron rating.

Why doesn't Cummins Filtration publish micron ratings for all its filters?

Generally this is not necessary. Cummins Filtration filters are designed to meet or exceed OEM specifications.
