Rust inside a fuel tank is a common problem for motorcycle riders, especially for those with older or used models. It is usually caused by long-term storage in humid environments, failure to use a fuel stabilizer, or leaving the tank open for extended periods. There are various methods for removing rust from a fuel tank, including using white vinegar, nuts and bolts, or an electrolysis technique. However, it is important to assess the condition of the tank and consider whether replacement might be a more cost-effective option.

Assess the tank's condition and consider replacement
Before you decide to repair a rusty fuel tank, it is important to assess the tank's condition and consider whether it needs to be replaced. Firstly, check a fuel sample by draining a small amount of fuel from the tank into a clear container. If you notice rust particles or debris in the fuel, it is a sign that the interior of the tank is severely corroded.
The condition of the tank is the most important factor in deciding whether to replace it or attempt to treat the rust. If the tank is too damaged, derusting may not be sufficient to fix the issue. Consider the rarity and desirability of the tank, as finding spare parts for classic or rare models can be challenging. On the other hand, if the motorcycle is newer or still available in dealerships, spare or aftermarket parts may be more readily available.
In some cases, the extent of rust buildup may be so significant that it warrants a complete tank replacement. Excessive rust can reduce the vehicle's performance and lead to costly repair jobs. Therefore, it is crucial to weigh the cost-effectiveness of either option—replacing the tank or spending time and resources on derusting and repairing the existing one.
Additionally, if the tank has cracks or small holes, you can temporarily seal them using rubber or vinyl vacuum caps. However, if the tank is severely damaged or corroded, these repairs may not be sufficient, and replacement may be the more prudent option in the long run.

Use rust treatment products like white vinegar
White vinegar is a readily available, inexpensive, non-toxic, and safe rust treatment product that can be used to fix a rusty fuel tank. The acetic acid in white vinegar dissolves the rust without damaging the underlying metal.
To use this method, start by removing the tank and emptying it of fuel. Seal any holes in the tank, including the filler cap and petcock outlet, with plugs, rubber or vinyl vacuum caps, corks, or masking tape. Next, pour in enough white vinegar to fill the tank halfway. You can also add a handful of small sheet metal screws, hardware, or BBs to act as agitators. Shake the tank gently so that the vinegar and agitators can reach all interior surfaces and loosen and dislodge the rust.
Let the vinegar sit and soak. The amount of time required will depend on the severity of the rust. For mild cases, you may only need to let it sit overnight, while more severe cases may require several nights or even up to two weeks. After soaking, drain the vinegar and flush the tank with clean water. To neutralize the vinegar, rinse the tank with a mixture of water and baking soda.
Once the tank is clean and dry, you can apply a coating product, such as Red-Kote, to the inside of the tank to prevent rust from returning.

Seal the tank with a product like Kreem
Sealing a rusty fuel tank involves cleaning the tank, removing the rust, and coating the inside of the tank with a sealant. This can be done using a product like Kreem, which offers a fuel tank liner kit. Here is a step-by-step guide to sealing a rusty fuel tank with Kreem:
First, wash out the tank with hot soapy water. If there is loose, flaky rust, add stones or nuts and bolts and agitate the tank to help remove the rust. For new tanks, it is important to remove any oily protective coating using a commercial degreaser or an industrial-strength detergent. Kreem offers a Tank Cleaner/Degreaser as part of its kit.
Next, remove any remaining surface rust and etch the metal surface. This can be done using Kreem's Tank Prep A & B Kit, which includes an acid etch that neutralizes existing rust. Repeat this step if necessary until all rust is removed. Then, rinse the tank with water, removing all traces of the acid etch, and drain out the excess water.
After the tank is clean and dry, it is time to apply the Kreem fuel tank liner. Pour the liner into the tank and slowly rotate the tank in all directions to coat the entire inner surface. Ensure that all surfaces are completely coated, with a generous excess remaining. Let the tank stand for 8-10 minutes with the spout open, then close the spout and slowly rotate the tank again, allowing the excess liner to re-coat all surfaces. Repeat this process for at least 24 hours, rotating the tank to a different side each time, until the desired coating is achieved.
It is important to note that Kreem is considered a temporary fix by some users, and there is a possibility that it may fail eventually. However, sealing a rusty fuel tank with a product like Kreem can be an effective way to address the issue without the expense and difficulty of replacing the entire tank.

Use electrolysis with sodium carbonate to remove rust
Using electrolysis with sodium carbonate is an effective way to remove rust from a fuel tank without damaging the underlying metal. This method is also known as the Semco Carbon process.
The first step is to assemble the required parts. You will need an automotive battery charger and cables, copper wiring connections, scrap wood for suspending the cathode, a mild steel bar parts holder, an electrolysis tank (an old cooler will work), and two rebar rods or graphite rods/plates. These rods will be used as sacrificial anodes that collect the rust during the removal process.
Next, create the electrolysis solution by mixing sodium carbonate with water. This solution allows the electrical current from the battery charger to flow from the cathode to the anodes. It is important to note that without the sodium carbonate, the electricity would dissipate in the tank, and the rust would not be removed.
Once the solution is prepared, it is time to begin the electrolysis process. This process requires time and patience, as it can take at least 24 hours or even longer to see serious results. During this time, the electrical current and the solution work together to safely remove the rust from the fuel tank.
Finally, after the electrolysis treatment, be sure to rinse the tank thoroughly with water to remove any remaining residue or solution.

Inspect the tank and consider replacing the fuel pump
Inspecting a fuel tank for rust is a crucial step in maintaining the health of your vehicle, especially if it has been exposed to extensive rust particles. Here are some detailed steps and considerations for inspecting a rusty fuel tank and deciding whether to replace the fuel pump:
Inspecting the Fuel Tank:
- Begin by checking a fuel sample. Drain a small amount of fuel from the tank into a clear container. The presence of rust particles or debris in the fuel is a strong indicator that the interior of the tank is severely rusted or corroded.
- Assess the severity of the corrosion. Look for signs such as rust flakes, pitting, or perforations in the tank. Consider the overall condition of the tank, including any cracks or small holes.
- Determine the feasibility of repairing the tank. In some cases, the damage may be too extensive, and replacing the tank might be more cost-effective. Consider the rarity and desirability of the vehicle, as finding spare parts for classic or rare models can be challenging.
Considering Fuel Pump Replacement:
- If the fuel pump has been exposed to a significant amount of rust particles, it is advisable to replace it. Rust particles can cause damage to the pump and impair its functionality.
- Replacing the fuel pump can help prevent future issues and ensure the smooth operation of the vehicle. A new fuel pump will be less likely to fail due to rust contamination.
- Fuel pump replacement is often recommended during a tank refinishing process. It ensures that the entire fuel system is refreshed and reduces the risk of rust-related problems.
- Cost is an important consideration. Evaluate the price of a new fuel pump and weigh it against the potential benefits of improved performance and reduced repair costs.
By carefully inspecting the fuel tank and considering the condition of the vehicle, you can make an informed decision about replacing the fuel pump. Taking proactive measures can help extend the life of your vehicle and avoid further complications from rust damage.
