Let the solution sit for 24 hours, then rinse the tank using a pressure washer.
Step 4: Prevent Future Rust
Seal your tank with a sealant to prevent future rusting. A fuel storage tank repair kit can also be used to temporarily fix any leaks or holes in the tank.
Other Methods
Other methods for removing rust include electrolysis, which uses a battery charger to create an electrical current to dissolve rust, and the chain shake method, which involves placing a chain in the tank and shaking it vigorously. Pickling metal is another process that removes rust and other impurities from metal surfaces.
Remember to always wear gloves and eye protection when working with rust removers and cleaning your fuel tank. Additionally, disconnect the battery and relieve the fuel system pressure before beginning any work to reduce the risk of sparks and fuel vapors.

Cleaning a cooling system with citric acid
Rust in the fuel tank can cause serious damage to your vehicle's performance. It can clog filters, leading to poor engine performance or even complete failure. Rust can also contaminate the fuel, causing issues such as engine failure. Therefore, it is important to clean your fuel tank and cooling system regularly to prevent rust buildup.
One method to clean a cooling system is by using a citric acid solution. Citric acid is known to de-rust and de-lime cooling systems. The process of flushing a cooling system with citric acid typically involves the following steps:
- Drain and flush the system using a kit or by running fresh water through it for 15-20 minutes.
- Drain the entire system again.
- Remove the thermostat.
- Mix a solution of citric acid and water. The concentration of citric acid can vary, with some sources recommending a 10% citric acid and 90% water solution, while others suggest dissolving 1 lb of citric acid in 1 gallon of water.
- Fill the system with the citric acid solution and run the engine for 15 minutes.
- Drain and flush the system again with fresh water for 5-15 minutes.
- Drain the system and fill it with an appropriate coolant/distilled water mix.
It is important to note that some people have reported component failures during the citric acid flush. Therefore, it is crucial to follow the manufacturer's instructions and take the necessary precautions when performing this procedure. Additionally, it is recommended to eliminate any oils present in the system before flushing, as this is a critical part of the process.
Another method to clean a diesel fuel tank of rust is by using a rust remover. Here are the steps:
- Empty the tank of any residual fuel and dry it thoroughly by leaving it in the sun for a few hours.
- Pour a commercial rust remover into the tank, seal it, and shake it vigorously.
- Let the remover sit for the recommended amount of time before draining it out.
- If the rust is stubborn, alternative methods such as electrolysis or the chain shake can be used. Electrolysis involves filling the tank with a baking soda and water solution and using a battery charger to create an electrical current that dissolves the rust. The chain shake involves placing a chain into the tank and shaking it vigorously.
- After removing the rust, remember to clean any tools used and wear gloves and eye protection for safety.
