Removing rust from the fuel tank
Removing rust from a motorcycle fuel tank can be a challenging task, but with the right tools and methods, it can be accomplished. Here is a step-by-step guide to help you through the process:
Inspect the Tank
Begin by removing the fuel tank from the motorcycle and emptying it of any remaining fuel. Examine the extent of the rust by shining a flashlight inside the tank. Look for flaking rust, thick scaling, or heavy deposits. This initial inspection will help determine the best course of action.
Mechanical Rust Removal
For heavy rust deposits, mechanical removal is often the most effective method. This involves using abrasive elements or agitators to strip the rust manually. Nuts, bolts, or even plain gravel can be placed inside the tank and shaken to dislodge stubborn rust. This process may need to be repeated several times to ensure all rust is removed.
Chemical Rust Removal
Once the majority of the rust has been mechanically removed, it's time to tackle the remaining rust chemically. One popular method is to use a mixture of cleaner degreaser and hot water to remove any gum, varnish, or sludge from the inside of the tank. Mix one quart of cleaner degreaser with one quart of hot water and pour it into the tank. Shake the tank to ensure all surfaces are coated, then drain and rinse thoroughly with water.
Dissolving Rust
After the initial cleaning, the next step is to dissolve any remaining rust and prepare the surface for sealing. This can be done using a product like POR-15 Metal Prep, which coats the tank with zinc phosphate and etches the metal for better adhesion of the sealer. Pour the entire bottle of Metal Prep into the tank, ensuring all rusty areas are coated.
Sealing the Tank
Once the tank is clean and dry, it's time to seal it to prevent future rust and corrosion. There are several products available for this purpose, such as the POR-15 Fuel Tank Sealer or Caswell epoxy. Carefully follow the manufacturer's instructions for applying the sealer to ensure a proper seal. Allow the sealer to cure completely before reassembling the fuel tank.
Preventative Measures
To prevent rust from returning, consider using a fuel preservation and stabilizer product to keep your fuel system in proper working order. Additionally, regular maintenance and proper fuel treatment before storing your motorcycle for extended periods can help prevent rust from forming in the first place.
Remember, always work in a well-ventilated area and wear appropriate protective gear when handling chemicals. With patience and attention to detail, you can successfully remove rust from your motorcycle fuel tank and restore it to its former glory.

Sealing the fuel tank
Step 1: Assess the Tank's Condition
Before sealing, it's essential to inspect the fuel tank's condition. Look for any signs of rust, corrosion, or pinhole leaks. Determine if the tank has been previously sealed and if there are any remnants of old sealants that need to be removed. This initial assessment will guide your approach to sealing.
Step 2: Clean and Prepare the Tank
Start by emptying the fuel tank and removing any residual fuel, debris, or water. For tanks with heavy rust deposits, mechanical methods such as using abrasive elements like nuts, bolts, or gravel can help strip the rust manually. Chemical treatments, such as mixing a cleaner degreaser with hot water, can also be used to remove gum, varnish, or sludge from the inside of the tank. Ensure the tank is thoroughly rinsed and dried before proceeding.
Step 3: Apply a Rust Inhibitor and Primer
To prevent future rust issues, apply a rust inhibitor or converter to the tank's interior surfaces. This will neutralize any remaining rust and create a protective barrier. After the inhibitor has dried, apply a primer to the tank's interior, ensuring better adhesion for the final sealant.
Step 4: Seal the Tank
There are various sealing options available, including epoxy-based sealants and fuel tank sealers like POR-15. Epoxy sealants provide a clear and durable coating that guarantees protection against gasoline and methanol. Fuel tank sealers, on the other hand, offer superior strength and fuel resistance, making the tank impervious to various additives and fuels. Carefully read and follow the instructions provided with your chosen sealant for optimal results.
Step 5: Final Inspection and Maintenance
Once the sealant has dried and cured, inspect the tank for any signs of uneven coating or missed spots. Ensure all holes and openings are properly sealed, using appropriate plugs, stoppers, or vacuum caps. Finally, implement fuel preservation and stabilizer measures to maintain your fuel system and prevent "stale gas" issues in the future.
Sealing your motorcycle's fuel tank is a meticulous process that requires patience and attention to detail. Depending on the severity of the tank's condition, you may need to repeat certain steps or adapt the process to address specific challenges. Always prioritize safety and follow manufacturer instructions for any products used during the sealing process.
