POR-15 Ultimate Fuel Tank Repair Kit
The POR-15 Ultimate Fuel Tank Repair Kit is a comprehensive solution for restoring and protecting fuel tanks. This repair kit is designed to address common issues with fuel tanks, such as rust, leaks, and corrosion. Here is a step-by-step guide on how to use the POR-15 Ultimate Fuel Tank Repair Kit:
Step 1: Surface Preparation
Before applying the POR-15 Fuel Tank Sealer, it is crucial to ensure that the fuel tank is properly prepared. The tank must be free from plastic parts, contamination, and any structural damage. Remove any loose rust, old sealers, or coatings using the POR-15 Cleaner Degreaser. This step ensures that the surface is clean and ready for the new sealer.
Step 2: Metal Treatment
Once the fuel tank is clean and dry, it's time to treat the metal surface for better adhesion of the sealer. Use the POR-15 Metal Prep solution, which helps dissolve rust, coat the tank with zinc phosphate, and etch the metal. This step is crucial for enhancing the bonding of the sealer to the tank's surface.
Step 3: Applying the Sealer
After the metal treatment, it's time to apply the POR-15 Fuel Tank Sealer. Make sure the tank is completely dry before pouring in the entire can of the sealer. This high-tech sealer is designed to be impervious to various types of fuels, including diesel, E10 ethanol, and high alcohol content fuels. It acts as a liner, providing superior strength and fuel resistance while preventing rust, corrosion, and small fuel leaks.
Step 4: Draining and Rinsing
After applying the sealer and ensuring all surfaces are coated, drain the tank for about an hour to remove any excess sealer. This step ensures that the excess sealer doesn't affect the fuel system's performance.
Step 5: Fuel Preservation
Once the sealing process is complete, it is recommended to use fuel preservation and stabilizer products to maintain your fuel system. This step helps prevent issues like "stale gas" and ensures that your fuel system remains in proper working order.
The POR-15 Ultimate Fuel Tank Repair Kit offers a comprehensive solution for restoring and protecting fuel tanks. By following these steps and properly applying the products, you can effectively address rust, leaks, and corrosion issues, ensuring the optimal performance of your fuel system. Remember to wear gloves and take the necessary precautions during the application process to avoid any skin contact with the sealer.

POR-15 Cleaner Degreaser
The POR-15 Cleaner Degreaser is a revolutionary breakthrough in metal cleaning and degreasing. It is designed to work quickly and efficiently, outperforming other cleaners, including petroleum-based ones. Its water-based formula means it can be diluted with water, making it more cost-effective and environmentally friendly. This product can be used in a variety of settings, including automotive, agricultural, industrial, and restoration applications.
One of the key advantages of the POR-15 Cleaner Degreaser is its ability to thoroughly clean and degrease surfaces without leaving any residue. This is especially important when preparing surfaces for painting, as any residue can interfere with the adhesion and appearance of the paint. Traditional solvent wipes and other cleaners often leave behind a film or residue, which can be detrimental to the final finish. However, with the POR-15 Cleaner Degreaser, users can be confident that the surface is thoroughly cleaned and ready for the next step in the process.
The product is available for purchase online through retailers such as Amazon and Advance Auto Parts. It comes in a 1-quart size, and users should follow the instructions on the package for proper dilution and application. It is important to note that this product may stain alloy surfaces, so it is recommended to test on an inconspicuous area first and dilute with water if necessary. After using the cleaner, it is important to thoroughly rinse the area with water, and for metal surfaces, to treat with POR-15 Metal Prep before painting.

POR-15 Metal Prep
POR-15 Fuel Tank Sealer is a high-tech product formulated for metal and developed as a sealer that is impervious to all fuels, including diesel, E10 ethanol, and high-alcohol-content fuels. This sealer acts as a liner and prevents rust, corrosion, and small fuel leaks. It is available in silver and has superior strength with fuel resistance.
Before applying the sealer, the fuel tank must be free from plastic parts, contamination, and structurally sound. The tank should be free from loose rust, old sealers, and cleaned with POR-15 Cleaner Degreaser. For the best adhesion, it is recommended to use POR-15 Metal Prep to etch the metal.
The POR-15 Metal Prep step is essential for preparing the metal surface and ensuring the successful application of the sealer. It helps create a strong bond between the metal and the sealer, which is crucial for the overall effectiveness of the repair. By dissolving rust and coating the tank with zinc phosphate, the Metal Prep creates a uniform and receptive surface for the sealer to adhere to.
It is important to follow the instructions provided by the manufacturer for the best results. The entire bottle of POR-15 Metal Prep should be poured into the tank to ensure proper coverage. After applying the Metal Prep, it is crucial to drain, rinse, and dry the tank thoroughly to create a clean surface for the sealer.
Overall, POR-15 Metal Prep is a vital step in the process of sealing a fuel tank with POR-15 Fuel Tank Sealer. By properly preparing the metal surface, the sealer can adhere effectively, creating a strong and durable barrier that prevents rust, corrosion, and fuel leaks.

Fuel preservation and stabilisation
One effective solution is to use a fuel stabilizer, a chemical additive designed to maintain the quality of gasoline or other fuels during storage. Fuel stabilizers prevent oxidation, extend the lifespan of fuel, and ensure trouble-free operation upon restarting the engine. They create a protective layer over the fuel, bonding with gasoline to prevent evaporation and the formation of sticky resins that can damage carburetors.
When choosing a fuel stabilizer, it is important to select one compatible with your engine type. Some stabilizers are designed specifically for gasoline or diesel engines, while others are suitable for two-stroke or four-stroke motors. Additionally, always follow the product instructions for the correct dosage and application process.
The optimal time to add a fuel stabilizer is when fuelling up, especially if the vehicle will be stored for an extended period. By adding the stabilizer to fresh fuel, you can maximise its effectiveness in preserving fuel quality. Most fuel stabilizers will preserve fuel for up to a year, although some can extend this period to two years.
For those with fuel-powered equipment like lawnmowers, chainsaws, or classic cars, a fuel stabilizer is an excellent way to ensure that their fuel remains stable and their engines run smoothly, even after extended periods of storage.

Seal All
The application process for the POR-15 Fuel Tank Sealer involves several steps. Firstly, it is important to prepare the fuel tank by ensuring it is free from plastic parts, contamination, and any structural damage. The tank should also be cleaned with POR-15 Cleaner Degreaser and etched with POR-15 Metal Prep for better adhesion of the sealer. After the tank is thoroughly cleaned and rinsed, it should be drained and allowed to dry completely.
Once the tank is dry, the entire can of Fuel Tank Sealer is poured in to coat all surfaces. After coating, the tank is drained for about an hour to remove any excess sealer. To maintain the fuel system, it is recommended to use fuel preservation and stabilizer to avoid issues with stale gas.
In addition to the Fuel Tank Sealer, POR-15 offers a range of complementary products. The POR-15 Rust Preventive Coating is designed to stop rust permanently on metal surfaces. It is non-porous and resistant to water, chemicals, and corrosion. This coating can be applied directly over surface rust and is known for its tough, hammer-resistant finish.
The POR-15 product line also includes repair kits, such as the Auto Fuel Tank Repair Kit, which can seal up to a 25-gallon tank, and the Motorcycle Fuel Tank Repair Kit, suitable for up to a 6-gallon tank. These kits provide a comprehensive solution for restoring and sealing fuel tanks, ensuring they function properly and extending their lifespan.
