Fuel Sampling for Diesel Generators

Fuel sampling is an essential part of diesel generator maintenance.

Crucial Fuel Maintenance

Fuel sampling is an essential part of diesel generator maintenance. It involves taking a small sample of the diesel fuel from the generator’s tank to test for impurities, water content, and other contaminants. Regular fuel sampling can help detect potential issues before they become major problems that can cause the generator to fail.

At Vital Power we’re specialists in all things generator and Uninterruptible Power Supply, so offer fuel sampling as part of our extensive fuel services range for generators. Here’s our guide to the service, informed by our years of experience in top-quality customer service.

Why is Fuel Sampling Important?

Fuel quality is crucial to the smooth operation of a diesel generator. Impurities, water, and other contaminants can cause engine failure, leading to costly repairs and downtime. Fuel sampling helps to identify any problems with the fuel before they can cause damage to the generator.

When Should Fuel Sampling be Done?

Fuel sampling should be done regularly, ideally every three to six months. Vital Power’s team can help create a custom schedule for generator maintenance to help upkeep stay manageable for your team. However, fuel sampling should also be done after the generator has been idle for an extended period, such as after a power outage or when the generator is being prepared for use after being in storage.

What is Fuel Sampling for Generators?

Fuel sampling is a simple process that can be done by a trained technician, like the members of the Vital Power team. Our experienced technician will use a special tool to extract a small amount of fuel (a sample) from the tank. The fuel is then tested for impurities and water content using specialist equipment.

There are several methods of testing the fuel, including visual inspection, water detection paste, and electronic fuel testers.

After the fuel has been tested, the specialist will analyse it to determine if any contaminants or impurities are present in the fuel supply. If any issues are detected, the technician will recommend the appropriate steps to correct the problem – which might include fuel polishing or another service.

What are the Benefits of Fuel Sampling?

Regular fuel sampling can help identify potential issues with the fuel in your generator before they cause damage to the generator’s engine and other machinery. It can also help extend the life of the generator and reduce the risk of downtime, which of course can be extremely costly for your bottom line. Fuel sampling can also ensure that the generator is running at optimal performance levels, and can help to improve the performance of diesel generators, extend the life of generator components, and reduce the risk of unplanned outages in a number of ways.

Some of the key benefits of regular fuel sampling for industrial generators:

Improved performance

Fuel quality testing and sampling can help to identify and correct problems with fuel that can cause poor performance. These can include things like water contamination, microbial growth, and the presence of contaminants such as dirt, rust, and sediment. Fuel quality testing can help to improve the efficiency and reliability of your diesel generator.

Extended generator life

Fuel sampling can help to identify and prevent problems with fuel that can cause premature wear and tear on generator components – such as injectors, fuel pumps and filters. By identifying and correcting these problems, fuel sampling can help to extend the life of generator components and reduce the cost of maintenance and repairs.

Reduced risk of outages

Regular fuel sampling can help to identify and prevent problems with fuel that can cause unplanned outages, such as clogging of fuel filters and injectors, and the formation of varnish and gum deposits. By identifying and correcting these problems, fuel management can help to reduce the risk of unplanned outages and keep diesel generators running when they are needed most.

Regulatory compliance

In addition to the benefits listed above, fuel sampling can also help to comply with environmental regulations and ensure the safety of personnel at your site. For example, fuel quality testing can help to identify and prevent the use of fuels or substances that contain harmful pollutants, such as sulfur and particulate matter. Additionally, fuel sampling can help to identify and prevent the presence of hazardous materials in fuel, such as lead and mercury.
