Keep a fire extinguisher nearby: Place a Class B or C fire extinguisher in close proximity to your workspace. Fuel is highly combustible, and having a fire extinguisher readily accessible will allow you to quickly address any potential fires or flames that may arise during the cleaning process. Ensure that the extinguisher is easily reachable and in good working condition.
Avoid flames and smoking: Do not smoke or introduce any sources of flame or sparks near the fuel tank during the cleaning process. This includes refraining from lighting matches, using lighters, or operating any equipment that may produce sparks, such as power tools without spark suppression. Inform others in the vicinity to also refrain from smoking or creating potential ignition sources. It is crucial to strictly adhere to this precaution to eliminate the risk of fire or explosion.
In addition to these safety measures, it is essential to wear appropriate protective gear, such as safety goggles, to shield your eyes from any chemical splashes or debris. Ensure that you handle fuel containers with care, keeping them tightly closed and gently handled to avoid spills. Always store fuel in approved containers or tanks and dispose of it in accordance with federal, state, and local guidelines. By diligently following these safety precautions, you can help ensure a safe and effective fuel tank cleaning process.

Draining the tank: Drain fuel into an approved container, then swirl and pour out remaining fuel
To clean a fuel tank, you must first drain the tank. This is a crucial step in maintaining the health and performance of vehicles and machinery. Over time, impurities and contaminants can build up in the fuel tank, affecting the engine's efficiency and longevity.
When draining the tank, it is important to use an approved container to catch the fuel. This is to ensure that the fuel is disposed of properly and safely. Once you have an approved container, you can begin to drain the fuel from the tank.
After draining as much fuel as possible, you will likely have some remaining fuel and debris in the tank. To remove this, swirl the tank to loosen any remaining particles, and then pour out the contents. You may need to repeat this process several times to ensure that all the fuel and debris are removed.
It is important to note that fuel is highly combustible, so extra care must be taken during this process. Ensure your workspace is well-ventilated and have a fire extinguisher on hand. Additionally, make sure that no one is working with an open flame or smoking near your workspace.

Removing the fuel pump: Take out the fuel pump and clean with a fuel-safe cleaner
It is important to clean your fuel tank from time to time to prolong the life of your fuel filter and engine. Fuel tanks must be constructed of a non-corrosive material or coated with a corrosion-resistant layer to protect against the damaging effects of water, alcohol, and salt. If your tank is corroded or damaged, it should be replaced.
Before removing the fuel tank, ensure it is empty. This is a safety precaution, and it also makes the process easier. Some fuel tanks have a drain cock, allowing the fuel to be drained neatly. If not, you can drain the fuel by removing a gas line or by siphoning it.
Now, carefully remove the fuel pump. Take out the fuel pump and clean it with a fuel-safe cleaner. You can use a product like Evaporust to remove corrosion from the fuel pump. Alternatively, you can clean it with a degreaser, rust remover, and water, and back and forth flush it. Repeat this process a few times over several days.
It is also recommended to use a fuel line antifreeze/water remover to help absorb any residual moisture. After the tank has dried, let it sit for 30 minutes.
Before reinstalling the fuel pump, carefully inspect the entire tank for any sediment, rust, or holes. Patch any holes before continuing. Use a parts cleaner, such as Berryman B-12 Chemtool Fuel System Cleaner, to disperse the product over the entire inside surface of the tank by shaking or swirling it. Keep in mind that the majority of the buildup will be at the bottom, so focus your attention there. It may take a few soaking sessions to get the bottom completely clean, depending on the amount of buildup.

Cleaning the tank: Use a low-suds soap and water mixture, or cleaning vinegar
To clean a fuel tank, you will first need to drain the tank. Remove the tank, then drain it of any remaining fuel. Turn the tank upside down and let the remaining liquid drain into a container. You may find that sludge or debris comes out with the gasoline.
If your tank still smells of gasoline, you will need to degrease it. Use a degreaser like Marine Clean, or a mixture of dish detergent and hot water. Let the degreaser or soap and water mixture sit in the tank for up to 24 hours.
Rinse the tank several times to ensure that suds and soap residue are completely removed. If you do not remove all chemical residue, you may damage your engine. After loosening built-up sediment and rust, empty and refill the tank to remove any remaining debris. Rinse the tank until there are no bubbles or foam in the water. This may require two to three rinses.
If you are using vinegar to clean your fuel tank, you can fill the tank with vinegar and leave it to sit for 24 hours. You can also add a handful of gravel, nuts, bolts, or BBs, then add vinegar and shake. After 24 hours, neutralise the vinegar with baking soda. Flush the tank with plenty of water afterwards.
Apple cider vinegar is a good option due to its high acidity. However, vinegar can damage rubber, so be cautious if there are any rubber fuel lines or fittings in the tank. Vinegar will also leave a strange grey residue, so you will need to wash and add something to prevent rust.
