The Best Way To Store Diesel Fuel For A Generator.

Diesel fuel has a high energy density and minimal volatility, making it a great option for running generators. Additionally, because of how effectively it burns, it is perfect for portable power tools and other equipment that need a consistent electricity supply.

The ability of a generator to function when needed depends on the storage of diesel fuel. When storing diesel fuel, it's important to keep the following in mind:

  1. Store diesel fuel in a cool, dry place, away from direct sunlight and heat sources.

  1. Use a fuel storage tank specifically designed for diesel fuel.

  1. Keep the storage tank full to prevent air from entering the tank, which can cause the fuel to deteriorate.

  1. Use a fuel stabilizer to help prevent the fuel from breaking down and becoming unusable.

Regularly check the fuel for contamination, and replace it if it has become contaminated.

It is also essential to follow all local regulations and guidelines for storing diesel fuel. It may include obtaining permits, meeting specific construction standards for the storage tank, and more.

Calculate the amount of fuel you require.

Decide how much energy you'll require before storing any fuel. It details the amount of power needed as well as how frequently you will require it. Multiplying the total number of hours you intend to run the generator by the typical running time per hour will yield these two figures.

Pick a suitable container.

Select a suitable container once you've calculated how much fuel you'll consume. You can use a metal tank rather than a plastic one if you reside in a chilly climate. Plastic tanks are more brittle than metal ones; hence they will shatter in high temperatures.

Add stabilizers or other additives.

Stabilizers are added to diesel fuel to prevent it from separating into different layers as it sits in storage. They also help keep the energy from freezing during the winter months. You can add them yourself by mixing them with the fuel at home. However, some people prefer to purchase pre-mixed fuels because they are easier to store and transport.

Seal it up tight.

If you plan to store diesel fuel for an extended period, seal the container tightly. It will prevent any moisture from entering the container and causing rust.

Label it clearly.

Make sure to label the container with the date you purchased it and the fuel type inside. You also need to label the container with what kind of fuel it contains (diesel, gasoline, etc.)


Diesel storage in tanks is the most favored technique for supplying the engine with a constant fuel supply. The fuel tanks can be either above or below the surface.

The fuel tank must be properly immersed to protect the fuel from cold weather. Another important factor while using the main fuel tank is the height difference between the primary and everyday tanks.

The distance between the two tanks' heights shouldn't be greater than five meters because electrical fuel lift pumps frequently have a maximum pumping height of that height. The fuel pressure on the suction line will drop if horizontal pipes or elbow pipes are used excessively, so keep that in mind as well.

Due to these factors, the positions of the fuel tanks and the pipe between them should be evaluated and defined. The size of the diesel supply and return lines should never be smaller than the size of the fuel connecting points on the engine, though they may need to be greater under some circumstances, such as during prolonged operations or in cold weather.

Steel or a substance suitable for petroleum should be for line pipes. Avoid using galvanized pipes. The tank overflow pipe needs to be one size larger and manufactured of the same material.

There shouldn't be any breaks or additional diesel return lines, and the tank should always be diesel from above the highest fuel level anticipated. The fuel return line should be built and piped with the least amount of elbow and bending points and length to prevent any potential airlock issues.

The fuel supply point of the tank to the diesel engine should not be taken from a height lower than 5 inches to the base of the tank to ensure that the fuel supply for the machine is sufficiently clean.

The fuel lines should be constructed with flexible pipes at the generator set's inlet points to minimize any potential problems brought on by vibrations.

What are the best ways to prevent diesel fuel from going bad?

There are several ways to prevent diesel fuel from going bad:

  1. Store diesel fuel in a cool, dry place with good ventilation to prevent moisture from collecting in the fuel.

  1. Use a fuel stabilizer to help prevent the fuel from breaking down and going bad.

  1. Keep the fuel tank full to minimize the air that comes into contact with the fuel, which can cause it to oxidize and go bad.

  1. Regularly check the fuel for water and contaminants, and remove them as necessary.

  1. Use the fuel as soon as possible to prevent it from breaking down and going bad.

  1. Consider switching to diesel fuel with a higher cetane number, which is more resistant to degradation.

By following these steps, you can help prevent diesel fuel from going bad and ensure that it is ready to use whenever you need it.

What are the best ways to use diesel fuel for a generator?

The best way to use diesel fuel for a generator is to make sure it is stored in a clean, airtight container and to check and replace the fuel filter regularly. It's also essential to use the correct type of diesel fuel for your generator, as using the wrong type can cause damage to the engine. 

Additionally, you should regularly check the oil level and change the oil according to the manufacturer's recommendations. It's also a good idea to run the generator regularly to ensure it is in good working order and to prevent the fuel from going bad.

What are the best ways to prevent diesel fuel from going bad?

There are several ways to prevent diesel fuel from going bad. The most effective way is to store it in a cool, dry place with a consistent temperature. It will help slow down the natural degradation process. You should also avoid exposing the fuel to direct sunlight, as UV rays can cause it to break down faster. Additionally, it's a good idea to use fuel stabilizers, which can help extend the shelf life of diesel fuel. Finally, use any fuel stored for a long time, as it may have already begun to degrade.
