What You'll Learn
Remove water, slime, and sediments
Water, slime, and sediments can cause significant issues in a diesel fuel tank, including filter clogging, reduced fuel flow, corrosion, and engine damage. To remove these contaminants and prevent problems, the following steps can be taken:
Firstly, it is important to drain the fuel tank completely. Place a fuel-catching container underneath the tank and unscrew the fuel line nut or hose at the base of the tank to allow the fuel to drain out. An extraction pump can then be used to remove any remaining fuel and sediment settled at the bottom of the tank. Leaving the tank to dry out is also recommended, as this will help to remove any residual water.
If your tractor is equipped with a water separator, it should be drained, and the fuel filters replaced. This will help to remove any water that has accumulated in the system.
To clean the fuel lines and prevent the growth of slime and sediments, flushing the lines with a detergent or a mixture of cheap ATF and acetone is recommended. Biocide treatments are also commonly used to kill bacteria and other contaminants. However, biocides can be toxic and may corrode the fuel system over time, so they should be used with caution.
To prevent the future buildup of water, slime, and sediments, fuel additives can be used. Clear-Diesel Fuel & Tank Cleaner is one such product that can remove water and slime, disperse contaminants, and stabilize fuel during long-term storage. It is important to use the correct amount of additive for your tank size, and additives should be used at least quarterly or as needed.
Using high-quality diesel fuel that is less likely to contain contaminants and impurities can also help prevent issues. Additionally, keeping the tractor's fuel tank topped off can reduce the likelihood of slime and sediment growth.

Use diesel fuel tank cleaner
Diesel fuel tank cleaners are an effective way to clean your tractor's diesel fuel tank. These cleaners are designed to remove water, slime, and other contaminants from the fuel, ensuring stable fuel performance during long-term storage.
To use a diesel fuel tank cleaner, follow these steps:
- Begin by removing the fuel cap and placing a fuel-catching container under the tank.
- Unscrew the diesel fuel line nut or hose at the base of the fuel tank to allow the fuel to drain into the container.
- Once the tank is empty, use an extraction pump to remove any remaining fuel and sediment from the base of the tank. You may also use an air compressor to blow out debris and ensure the tank is clear.
- Reattach the fuel line and secure it in place.
- Add the diesel fuel tank cleaner to the tank. Refer to the manufacturer's instructions for the correct amount to use, as it will depend on the size of your tank and the severity of the contamination.
- Replace the fuel cap and start the engine.
- Bleed your fuel system to remove any air and ensure the engine runs smoothly. Refer to your tractor's owner's manual for specific instructions on bleeding the fuel system, as it may vary depending on the model.
It is important to use a diesel fuel tank cleaner that is suitable for your tractor and follow the manufacturer's instructions for proper usage. These cleaners are designed to dissolve water and contaminants, improving engine performance and reducing the risk of fuel system blockages.
Additionally, regular use of diesel fuel tank cleaners can be a vital part of preventive maintenance, especially if your tractor is used infrequently or exposed to extreme weather conditions. By following these steps and using a diesel fuel tank cleaner, you can effectively clean your tractor's diesel fuel tank and maintain its optimal performance.

Clean fuel injectors
To clean the fuel injectors of a diesel fuel tank in a tractor, you must first drain the tank. Place a fuel-catching container underneath the tank and remove the fuel cap. Once the tank is drained, use an extraction pump to remove any remaining fuel and sediment.
You can then use an air compressor to blow out debris and clean the fuel lines. Insert the nozzle of the air compressor into the hose and blow air back towards the tank. After blowing out the lines, replace and secure them.
If your tractor has a water separator, drain this and replace the fuel filters. Fill up the tank with fresh diesel fuel and pour in the correct amount of diesel fuel tank cleaner. This will remove water, slime, and other contaminants.
Finally, replace the fuel cap and start the engine. Bleed your fuel system. If your tractor is a later model, turn the key on and allow the electric fuel pump to flow fuel up to the filters. Crank the engine over until it self-bleeds and starts. If your tractor has injection pumps, open the bleeder screw where the fuel line meets the injection pump. Open the screw to purge air and crank the engine until it starts. When the engine starts, close the screw.

Prevent diesel bug
Diesel bug is a colloquial term for the microbial and bacterial organisms that contaminate diesel fuel and similar petroleum products. These microbes cannot survive in clean fuel or water alone but thrive at the interface of diesel and water, where they feed on hydrocarbons in the fuel and create a thick, dark brown to black sludge that can damage your tank and engine.
To prevent diesel bug, it is important to minimise the presence of water in your fuel tank as much as possible. Water can enter the tank through condensation, rainwater ingress, or absorption from the air. Keep your fuel tank topped up, as full tanks have less room for moisture accumulation. Regularly test your fuel and remove any water that is present. Fuel tank water absorbers, such as Aquafighter, can be used to remove free, suspended, and emulsified water from the tank.
Additionally, use biocides or diesel fuel additives with biocide/HUMbug preventative to treat your fuel and prevent diesel bug growth. These additives can be purchased from fuel stations and added to your fuel tank to control bacteria and sludge formation.
Practising good fuel husbandry and regularly testing and maintaining your fuel tank will help prevent diesel bug and avoid costly repairs due to fuel system damage.

Drain and refill the tank
To drain and clean your diesel fuel tank, you will need to remove the fuel cap and place a fuel-catching container under the tank. Unscrew the fuel line nut or hose at the base of the fuel tank and let the tank drain. Use an extraction pump to remove any remaining fuel and sediment at the base of the tank. You may need to blow out debris with an air compressor.
After this, the tank will be empty and ready for refilling. Before refilling, you should inspect the inside of the tank for any signs of damage or corrosion. Use a mirror to check the top inside of the tank for rust. If there is an inspection port, you can use a torch to look inside and check for any slime or algae that may have grown due to fuel being stored in translucent containers in sunlight.
If there is significant rust, the tank may need to be replaced or cut and a new piece added. If there is slime or algae, you can use gasline deicer to kill the bacteria and break up the mass. You can also use a garden sprayer to spray down the inside of the tank and use a cleaning solvent to cut the diesel. Let the tank air dry in the sun.
Once the tank is clean and dry, you can refill it with fresh diesel fuel. Add the correct amount of diesel fuel tank cleaner and replace the fuel cap. Finally, bleed your fuel system. Consult your owner's manual to identify which system you have and for further details.
