Cleaning out an aluminum diesel fuel tank can be a challenging task, especially if the tank is built-in and cannot be easily removed. The first step is to identify the type of residue or contamination present, such as old gasoline, varnish, sludge, or rust. The next step involves choosing an appropriate cleaning method and solution. Some common approaches include using fresh gasoline, E85 gasoline, kerosene, paint thinner, or commercial products like Eagle 1 A to Z Wheel Cleaner, Gumout, Pyroil, Holley, or CRC. It is important to follow safety precautions, such as wearing protective gear, when handling cleaning agents. Additionally, testing the tank for leaks after cleaning is crucial to ensure its integrity.

What You'll Learn
Removing the tank from the vehicle or boat
Before removing the tank from your vehicle or boat, ensure you are wearing safety gear, including gloves and safety glasses. It is also important to work in a well-ventilated area away from any open flames or objects that could cause sparks, such as pilot lights and incandescent light bulbs. Remember to have clean-up materials ready in case of any spills.
Firstly, siphon the fuel out of the tank and store it in an approved container. To do this, insert a siphon pump or a length of tubing into the tank until it reaches the fuel. Then, create suction using the pump (never your mouth) and direct the fuel into your container.
Once the tank is empty, disconnect all the hoses and electrical connectors. There will likely be multiple hoses, including supply lines, return lines, and vent hoses. Ensure they are all disconnected before moving on to the electrical connectors.
Now, you can remove the metal straps that hold the tank in place. Be careful and thorough throughout this process, checking for any access panels that may provide an easier alternative to removing the tank.
If you are cleaning a boat's fuel tank, it is important to address any water contamination. Water can enter the fuel tank due to condensation, damaged seals or gaskets, leaks in the fuel pump, a contaminated fuel nozzle, or leaving the fuel tank cap off. Detecting and removing water contamination is crucial to prevent engine issues, decreased performance, and potential damage.

Using a metal chain to remove rust
To clean out an aluminium diesel fuel tank, you'll need to remove any diesel sludge, which is an algae-like substance that adheres to the tank's surface.
One way to do this is by using a chemical cleaner, such as Eagle 1 A to Z Wheel Cleaner, Gumout, Pyroil, Holley, CRC, Chevron Techron (PEA), Berryman, SeaFoam, or xylene. These products can be sprayed or poured into the tank and then rinsed out with water. Another option is to use a fuel tank cleaner kit, such as the KBS Fuel Tank Sealer System, which includes a cleaner, a rust remover, and a sealer.
If your fuel tank is rusty, you will need to address that separately before refilling the tank with diesel. One way to remove rust is by using a metal chain. Here's a step-by-step guide:
First, inspect the tank for rust. Check the exterior for paint flaking or peeling, which could indicate that the metal has weakened. Open the gas tank cap and shine a flashlight inside to check for rust. The thicker and flakier the rust, the more difficult it will be to remove. You can also drain a small amount of fuel into a clear container to check for rust particles or debris, which would indicate severe rusting or corrosion.
If the tank is severely rusted, you may need to consider replacing it. Otherwise, you can attempt to remove the rust using a metal chain. Here's how:
- Choose an appropriate acid for rust removal. The safest acid to use is white vinegar (acetic acid), which is inexpensive, non-toxic, and widely available. It takes longer to work, but it is less likely to damage the metal. Other options include phosphoric acid or muriatic acid, which are more potent and act faster but require appropriate protective equipment due to stronger fumes.
- Prepare the acid solution according to the manufacturer's instructions and the desired rust removal strength. The water-to-acid ratio will vary depending on the acid used.
- Pour the acid solution into the fuel tank until it is roughly half full.
- Add metal objects, such as nuts, bolts, or a section of the metal chain, to act as agitators. These objects will help scrape away loose rust and dislodge particles.
- Seal the openings of the fuel tank securely.
- Shake the tank gently to ensure that the acid solution coats all interior surfaces.
- Let the tank sit and soak for the recommended time. The stronger the acid, the shorter the soaking period. Vinegar may take several hours or overnight, while stronger acids may only need 15 minutes.
- After soaking, drain the acid solution from the tank and dispose of it safely. Follow safe acid disposal practices, such as tipping the tank upside down and shaking out any remaining agitators.
- Rinse the tank with a baking soda solution to neutralize any acid residue and prevent damage to the metal.
- Drain the tank again and rinse it with clean water.
- If needed, repeat the process until all rust is removed.
- After the final rinse, ensure the tank is thoroughly dried using a heat gun or blow dryer.
- Finally, inspect the tank for any remaining rust and replace the seals as necessary before refilling the tank with diesel fuel.
Using a metal chain and an acid solution can be an effective way to remove rust from a diesel fuel tank. Always work in a well-ventilated area and wear appropriate protective equipment when handling chemicals.

Soaking with E85 gasoline
E85 gasoline is an effective way to clean the inside of an aluminium diesel fuel tank. It is a fuel blend made up of 85% ethanol and 15% gasoline. Ethanol acts as a solvent, removing deposits and cleaning the inside of your tank.
To clean your tank using E85 gasoline, start by draining as much of the existing fuel from the tank as possible. Next, pour in the E85 gasoline. The amount of E85 gasoline you'll need will depend on the size of your tank, but ensure you have enough to completely cover the interior surfaces of the tank. After pouring in the E85 gasoline, seal the tank closed and let it soak for one to two weeks.
During the soaking period, the ethanol in the E85 gasoline will dissolve and remove any varnish, grime, or deposits from the tank's interior surfaces. Ethanol is particularly effective at removing carbon deposits, which can build up over time and impact the performance of your engine.
After the soaking period, you can drain the E85 gasoline from the tank. If you wish, you can filter and reuse the E85 gasoline, for example, by burning it in a lawnmower. Finally, rinse the tank with fresh gasoline and you're done!
It is important to note that while E85 gasoline is a convenient and effective cleaner, it is not suitable for all vehicles. E85 is only recommended for factory-built Flex-Fuel Vehicles (FFVs). Using E85 in a vehicle not designed for it can be corrosive and damaging to the fuel system. Always check your vehicle's specifications before using E85 gasoline for cleaning or fuelling purposes.

Acid wash or fuel tank cleaner
To clean out an aluminium diesel fuel tank, you can use an acid wash or a fuel tank cleaner.
If you choose to use an acid wash, you must first fill the fuel tank with water and then add a cup of muriatic acid. Dispose of the contents of the tank properly and repeat this process until the wash becomes clear. It is important to wear protective gear when handling acid to avoid any contact with your skin or inhaling the fumes.
Alternatively, you can use a fuel tank cleaner. There are several products available on the market, such as Clear-Diesel Fuel & Tank Cleaner, which can be added directly to the fuel. This product removes water, disperses contaminants, and stabilizes fuel during long-term storage. It is important to follow the instructions on the bottle or container of the fuel tank cleaner you choose.
After washing with either method, you may want to leave the tank overnight with a weak acid solution or weak fuel tank cleaner inside. The next day, empty the tank and wash it with water to remove any remaining chemicals and particles. Before installing the tank back into your vehicle or boat, ensure that it is completely dry to avoid any issues.
Other methods for cleaning an aluminium diesel fuel tank include using kerosene, paint thinner, or fresh gasoline. Some people also recommend using a carb cleaner or a product like Eagle 1 A to Z Wheel Cleaner to loosen any caked-on sludge without damaging the metal.
