Repairing a motorcycle fuel tank can be a challenging task, but with the right tools and knowledge, it is certainly achievable. One of the most common issues with motorcycle fuel tanks is leakage, which can be caused by compromised seams, pinholes, or rust and corrosion. To address these problems, various methods can be employed, such as using epoxy-like tank sealers or solder. Additionally, there are commercial repair kits available, such as the POR-15 Motorcycle Fuel Tank Repair Kit, which is designed to seal leaks, prevent rust and corrosion, and restore the tank to a better-than-new condition. When deciding on a repair method, it is important to consider the type of fuel tank, as some methods may be more suitable for certain materials than others.

What You'll Learn
Repairing pinhole leaks
One popular method for repairing pinhole leaks is to use an epoxy-like tank sealer. This can be applied directly to the leak to seal the hole. Some products that can be used include JB Weld, Waterweld, and regular household epoxy. However, it is important to note that these repairs may only be temporary, as some users have reported the gas leaking through again after a week.
Another option is to use a fuel tank repair kit, such as the POR-15 Motorcycle Fuel Tank Repair Kit. This kit includes a cleaner degreaser to remove any sludge or varnish, a metal prep to remove rust and prepare the tank for sealing, and a fuel tank sealer to create a permanent seal. This option may be more time-consuming, but it can provide a more durable solution.
Before applying any sealant, it is important to prepare the area by removing any rust or old paint. This will help ensure that the repair is successful and that the sealant adheres properly. Some users have reported success with using Bondo, a filler material, to repair pinhole leaks. This may be a more semi-permanent solution, but proper preparation of the area is key to its effectiveness.
In some cases, it may be necessary to replace the fuel tank entirely, especially if the leaks are severe or the tank is heavily rusted. This can be a more costly option, but it may be the best solution to ensure the safety and functionality of the motorcycle.

Using epoxy-like tank sealers
Epoxy-based sealers can be used to repair a motorcycle fuel tank. This method is suitable for repairing, sealing, and shielding metal fuel tanks from internal rust. Before applying the epoxy, the tank must be thoroughly cleaned and dried. It should be free of grease and rust, and any old sealant or paint should be removed.
To use an epoxy sealer, start by mixing the two-component epoxy resin together thoroughly. Then, empty the mixture into the fuel tank and seal the filler opening. Ensure that the sealant touches all surfaces to form a good layer. Next, drain the excess sealant by turning the tank upside down.
For plastic fuel tanks, epoxy glue can be used to seal small holes or tears. First, drain the gasoline from the tank and allow it to dry. Then, apply the epoxy glue to the affected area, following the instructions on the product. Allow the glue to dry and sand the area if needed. Finally, spray the patched area with plastic paint if desired.
When using epoxy to repair a motorcycle fuel tank, it is important to choose a suitable product and follow the safety instructions provided by the manufacturer. Some epoxy products may not be compatible with certain types of plastic or metal tanks, so it is advisable to test a small area first. Additionally, some epoxy products may be resistant to gasoline and petroleum, while others may soften when exposed to modern fuel.

Soldering
- Drain all the fuel from the tank and dry the inside.
- Remove the paint on the iron plate and polish the affected area with a wire brush until the metal surface appears.
- Apply a special flux for sheet metal to the affected area and its surroundings. Use a brush for a clean and waste-free application.
- Warm the affected area with a soldering iron. Ensure that the base material is sufficiently heated; otherwise, the solder will not run into the metal.
- Melt the solder and run it into the affected area. Be careful not to overheat the base material, as it may cause the solder to round due to surface tension.
- After repairing, dry the inside of the fuel tank by pouring a small amount of neutral detergent and then slowly adding tap water to wash away any remaining dirt or grease.
It is important to use a special solder and flux designed specifically for sheet metal. Additionally, ensure that the affected area is thoroughly cleaned and treated with flux before soldering. Soldering can be a challenging process, and it is recommended to consider using an epoxy sealer or a repair kit as an alternative to soldering.

Removing rust
The first step is to purchase a reliable fuel tank repair kit that includes a cleaner or degreaser to remove any sludge, gum, or varnish buildup inside the tank. This step is crucial as it prepares the tank for the rust removal process and ensures that the treatment can be applied effectively.
Once the tank is cleaned, you can move on to the rust removal stage. Using a metal prep solution or a similar product, treat the inside of the tank to eliminate rust and prepare the surface for sealing. Follow the instructions provided with your chosen product for the best results.
After the rust has been successfully removed, it's time to seal the tank. Apply a fuel tank sealer to create a permanent seal. This step will ensure that your fuel tank is impervious to leaks and will prevent future rust and corrosion.
Finally, allow the sealer to dry thoroughly according to the manufacturer's instructions. This step is crucial to ensuring that the repair is successful and long-lasting. Once the sealer is dry, your motorcycle fuel tank will be restored, looking better than new and ready for use.
By following these detailed steps, you can effectively remove rust from your motorcycle fuel tank, ensuring a safe and reliable fuel system for your bike.

Preventing corrosion
Use a Fuel Tank Repair Kit: Consider investing in a high-quality fuel tank repair kit, such as the POR-15 Motorcycle Fuel Tank Repair Kit. This kit is specifically designed to stop rust and corrosion and seal pinhole leaks. It includes a cleaner degreaser to remove gum, sludge, and varnish, metal prep to eliminate rust, and a fuel tank sealer. Follow the detailed instructions provided with the kit for a successful tank restoration.
Regular Cleaning and Maintenance: Establish a regular cleaning and maintenance routine for your fuel tank. This includes removing any gum, sludge, or varnish buildup using a suitable cleaner. Regular cleaning helps prevent the formation of rust and corrosion, ensuring the tank remains in good condition.
Sealing and Protection: After thoroughly cleaning and drying your fuel tank, apply a sealer specifically designed for fuel tanks. A good sealer will create a permanent barrier, protecting the tank from rust and corrosion. Ensure that all areas of the tank are coated evenly, paying extra attention to corners and crevices where corrosion commonly occurs.
Preventative Measures: Take preventative measures to minimize the risk of corrosion. Always store your motorcycle in a dry and covered area to protect it from the elements. Regularly inspect the fuel tank for any signs of damage, such as dents or scratches, and address them promptly. Additionally, consider using fuel additives that help inhibit corrosion and maintain the integrity of the tank.
Vintage Motorcycle Care: If you own a vintage or classic motorcycle, pay extra attention to the fuel tank. Older tanks are more susceptible to corrosion due to the age of the materials used. Consider using a repair kit specifically designed for vintage motorcycles, as mentioned earlier, to restore and protect the fuel tank.
By following these steps and adopting a proactive approach to maintenance, you can effectively prevent corrosion in your motorcycle fuel tank, ensuring the long-term health and performance of your vehicle.
