Cleaning a fuel tank is an important aspect of vehicle maintenance, as it helps to maintain the health and performance of the engine. Over time, impurities and contaminants can accumulate in the fuel tank, leading to issues such as reduced gas mileage and clogged fuel filters. While it is recommended to remove the fuel tank for cleaning, there are also methods for cleaning the tank without removal. This involves draining the tank, cleaning the interior with a suitable cleaning solution, rinsing, drying, and refilling the tank with fresh fuel. Safety precautions must be taken when working with fuel due to its highly combustible nature.

What You'll Learn
Drain the tank
To drain a fuel tank, it is recommended that you first drain the old fuel into an approved container. This is an important step to ensure that you are working safely with fuel, as gasoline is highly combustible. It is also important to work in a well-ventilated area, and to keep a fire extinguisher on hand.
After draining the fuel, you can then remove the fuel pump and clean the interior of the tank. One method is to use a fuel-safe cleaner and a brush to scrub away any built-up grime. You could also try using cleaning vinegar or evaporust, or adding paint thinner with nuts and bolts and shaking the tank to loosen debris. Another option is to use a pressure washer to lift loose material, or to try a fuel tank cleaning kit with a low-suds cleaning solution.
Once the tank is clean, it should be rinsed and dried with compressed air or a lint-free cloth. It is important to ensure that the tank is completely dry before refilling it with fresh fuel.
In addition to draining and cleaning the tank, you may also need to clean the fuel pump and fuel lines, as these can become clogged with the same contaminants.

Clean the tank's interior
Cleaning the interior of a fuel tank is a tricky but important job. Fuel tank cleaning is essential for maintaining the health and performance of vehicles and machinery. Over time, impurities and contaminants can accumulate in the fuel tank, affecting the engine’s efficiency and longevity.
Firstly, you need to drain the tank. This is done by draining the old fuel into an approved container. You can then swirl the tank and pour out any remaining fuel and debris. It is important to remember that gas is highly combustible, so proper safety precautions must be taken. Ensure your workspace is well-ventilated and keep a fire extinguisher close by.
Next, you can begin to clean the tank's interior. You can use a low-suds soap and water mixture, or a fuel-safe cleaner, and a brush if needed. You could also try using cleaning vinegar or evaporust, or adding paint thinner with nuts and bolts and shaking the tank to loosen debris. Another option is to use a pressure washer to lift loose debris.
Once you have cleaned the tank, you need to rinse and dry it. You can use compressed air or a lint-free cloth to dry the tank, and a heat gun can also be used to speed up the process. It is important to ensure the tank is completely dry before reinstalling and refilling.

Rinse and dry the tank
Rinsing and drying the fuel tank is an important step in the fuel tank cleaning process. It is recommended to use a low-suds soap and water mixture for rinsing the tank. Swirl the cleaning solution inside the tank to ensure that all the interior surfaces are thoroughly rinsed. You can also use cleaning vinegar or evaporust for rinsing.
After swirling the cleaning solution, drain the tank completely and prepare it for drying. One effective way to dry the tank is to use compressed air. Direct the compressed air into the tank to blow out any remaining water or moisture. You can also use a lint-free cloth to absorb any residual water and ensure that the tank is thoroughly dried.
It is crucial to confirm that the tank is completely dry before proceeding to the next steps. Approximately 30 minutes should be allowed for the tank to air dry after using compressed air or a cloth. Inspect the tank visually to ensure no water droplets or moisture is present. Any residual moisture can lead to contamination and affect the performance of the fuel system.
Additionally, you can use a heat gun as an alternative method to speed up the drying process. Heat guns emit hot air that evaporates any remaining water quickly. However, it is essential to use the heat gun with caution and follow the necessary safety precautions to avoid any potential hazards. Always ensure that the workspace is well-ventilated and that flammable materials are kept away during the drying process.
Once the tank is completely dry, you can proceed to the next steps of reassembling the fuel system. Reinstall the fuel pump, refill the tank with fresh fuel, and replace the fuel filter. It is important to use fresh fuel to prevent any contaminants from re-entering the clean tank. Proper maintenance of the fuel tank and fuel system is crucial for the engine's performance and longevity.

Reinstall and refill the tank
Once your fuel tank is clean, dry, and free of contaminants, you can begin the process of reinstalling and refilling it.
Firstly, ensure the tank is completely dry. Use compressed air or a heat gun to speed up the drying process. It is vital that the tank is completely dry before refilling with fuel, as any moisture left in the tank can cause issues.
After confirming the tank is dry, you can begin the reassembly process. Reinstall the fuel pump and any other components that were removed during the cleaning process. Ensure all connections are secure and properly tightened.
Now, you can refill the tank with fresh fuel. It is important to use fresh fuel to prevent any new contamination. Additionally, consider using a fuel treatment product to enhance the fuel's performance and protect the engine. These treatments can improve lubrication, boost power, and prevent corrosion and moisture buildup.
Finally, remember to replace the fuel filter after refilling the tank. This will ensure that any contaminants removed during the cleaning process will not re-enter the fuel system.
By following these steps, you can effectively reinstall and refill your fuel tank, ensuring optimal performance and longevity for your vehicle's engine.

Use a fuel tank cleaning kit
Using a fuel tank cleaning kit is an effective way to clean your fuel tank. There are a few options available on the market, such as the Delphi Technologies Fuel Tank Cleaning Kit (FFC01) or the Bilt Hamber Fuel Tank Cleaning Kit. These kits provide a convenient and relatively straightforward solution to fuel tank cleaning.
The Delphi kit includes a low-suds cleaning solution designed for up to 40-gallon tanks. It removes microbial growth, breaks down contaminants such as varnish and gel from ethanol, and minimises sludge. The kit also contains gloves and a lint-free cloth for the cleaning process. This product has received positive reviews from customers, who have found it effective and easy to use.
The Bilt Hamber kit takes a slightly different approach. It includes Deox-C, a crystalline product that, when dissolved in tap water, creates a powerful rust-removing liquid. This solution is designed to clean heavy corrosion from the interior of the fuel tank. It also comes with Surfex-HD, a biodegradable pre-treatment cleaner that strips fuel residues, oils, and various soils. This kit requires 19 litres of hot water for the cleaning process and is most effective when the fuel tank is removed from the vehicle.
When using a fuel tank cleaning kit, it is important to follow the specific instructions provided by the manufacturer. However, there are some general steps that can be outlined. Firstly, drain the fuel tank and clean any rust or debris from the top of the tank. Then, remove the fuel pump and swirl the tank to remove any remaining fuel and debris. After that, pour in the cleaning solution, swirl it around the tank, and then drain and dry the tank. Finally, inspect the tank for any damage and ensure it is completely dry before refilling it with fresh fuel.
By following these steps and using a reputable fuel tank cleaning kit, you can effectively clean your fuel tank, removing contaminants, microbial growth, and corrosion. This will help improve the performance of your vehicle and extend the life of the fuel sending unit and fuel pump. Remember to always prioritise safety when working with fuel and ensure your workspace is well-ventilated.
