What is a diesel fuel tank?

Like many other pieces of machinery, commercial and industrial generators typically run on diesel. The diesel fuel tank is the storage unit for the diesel supply, and this system provides a continuous stream of clean fuel to the generator when it is needed. The most common option for backup generators is the sub-base style, where the generator is mounted directly on top of the fuel tank. When the physical size limit of a sub-base fuel tank isn’t enough, entirely separate units can be used. These are a popular choice when generator usage is regular and on a large scale.

During an extended power outage, an uninterrupted stream of clean fuel is fundamental to ensure the continued operation of your generator and its ability to service the required appliances. A diesel fuel tank is the most straightforward and effective way to ensure your generator is always fully fuelled and operational when it is needed.

How does a diesel fuel tank work?

A generator requires a continuous stream of clean fuel while in operation. Insufficient or lapses in supply can lead to unexpected breakdowns, lower-load potential and even irreversible damage to the appliances relying on this generator. A diesel fuel tank is a system used to deliver fuel to a generator, and these devices may be fitted onto the generator or could be an entirely separate unit. Bulk fuel is typically stored in a large tank and then transferred to a smaller day tank near the engine or into a sub-base tank. This fuel is generally transferred between the storage unit and the fuel tank by an electrical motor-driven pump.

Once held in the day tank, a delivery line to the generator will deliver fuel as required. The two units should be located close to each other, and the connecting line must be no smaller in size than the fittings on the engine. After receiving the diesel, the generator will convert this fuel into energy, which is outputted as power for the required appliances or servicing. The level of fuel needed depends on the size of the generator and the intended use. From purchase and installation to generator maintenance and repairs, you can trust Reactive Generators to get the job done.

Why is a diesel fuel tank important?

A diesel fuel tank is an exceptional opportunity to regulate the storage of fuel and ensure the generator can perform when it is required. As the fuel may be stored for long periods between use, sediment can accumulate over time. If the fuel is stored inside the generator, this build-up of solids would create blocks, hinder the unit’s operation and compromise it’s expected lifespan. Storing the fuel in an external fuel tank will minimise the likelihood of condensation accumulation and dirt contamination.

A large-capacity storage tank is preferable, as this promotes bulk purchases and minimises the likelihood of contamination. Having large quantities of fuel on demand ensures you’re always equipped to deal with the unpredictable and unavoidable nature of power outages. Larger units are also recommended for bigger commercial establishments or where power outages are frequent and long-lasting.

How Do You Select the Right Diesel Fuel Tank?

Diesel fuel tanks come in a variety of different sizes and styles. The most appropriate selection depends on several factors, including the nature of business operations, consumption rate, required running hours and the availability of fuel. Many commercial and industrial entities opt to store more fuel than they expect to use, as the length and frequency of power outages can be challenging to predict.

Maintaining a Diesel Fuel Tank

Storing fuel in a diesel fuel tank will inevitably attract a build-up of silt and water over time. If left to accumulate, this sediment can cause significant and sometimes irreversible damage to the generator and other appliances. Periodically drawing water and sediment from the diesel fuel tank is fundamental to maintaining the unit, and will help eliminate bacteria and other foreign bodies. This process can be conducted in conjunction with a routine maintenance check by Reactive Generators.

Ground settling must also be taken into consideration when installing the generator and diesel generator tank. The potential issues presented by movement and changes in stresses within the earth can be avoided by keeping the drain cock at the lowest level and routinely removing water by pumping through a tube down the fill pipe. The impact of seasonal settling can also be reduced by burying the tank below ground to protect it from severe weather conditions.
