What You'll Learn
Prepare the tank by removing rust and contaminants
To prepare your tank for POR 15 Fuel Tank Sealer, it is essential to remove rust and contaminants. This process ensures the tank is clean and properly prepped, which is crucial for achieving optimal results. Here is a detailed guide to help you through the process:
Firstly, it is important to assess the condition of your tank. If there is visible rust, it needs to be removed. Start by using a product like Evapo-Rust or Metal Rescue to eliminate rust from the tank. These products are designed to effectively remove rust without damaging the metal. Follow the instructions on the product you choose for the best results.
Once the rust is removed, it's time to neutralise any acids and ensure the tank is thoroughly cleaned. This step is crucial as it prepares the surface for the sealer and ensures its adhesion. One effective method is to use a solution of vinegar and distilled water, followed by baking soda and water to neutralise the acid. Swirl these solutions inside the tank and repeat if necessary. Then, rinse the tank thoroughly with water to remove any residue.
After neutralising, the tank must be dried completely. Use an air hose or a hair dryer to ensure all moisture is removed. This step is critical because applying the sealer to a damp surface can affect its adhesion and effectiveness. Make sure the tank is at an appropriate temperature before proceeding to the next step.
Before applying the sealer, it is important to ensure the tank is free from any contaminants. This includes removing old sealers or coatings that may be present. Use a suitable stripper or cleaner, such as POR-15 Strip Gel, to remove any residual contaminants. Follow the instructions on your chosen product for safe and effective use.
Finally, prepare the surface for optimal adhesion. This step may involve using a product like POR-15 Metal Prep, which can help dissolve any remaining rust and etch the metal for better sealer adhesion. Follow the instructions on the Metal Prep product, ensuring you coat the tank evenly. Once the preparation is complete, your tank is ready for the application of POR 15 Fuel Tank Sealer.
Remember, proper preparation is key to achieving the best results with POR 15 Fuel Tank Sealer. Take your time with each step, ensuring the tank is clean, rust-free, and properly prepared before applying the sealer.

Use a hair dryer to ensure the tank is completely dry
To use POR 15 fuel tank sealer, it is important to ensure that the tank is completely dry before applying the sealer. One way to do this is by using a hair dryer.
First, clean the tank thoroughly to remove any dirt, grease, or rust. This can be done using various chemicals, such as vinegar, baking soda, and distilled water, or products like Evapo-Rust, Metal Rescue, or the POR-15 Cleaner Degreaser. It is important to neutralize any acids used and to rinse the tank thoroughly after cleaning.
Once the tank is clean, use a hair dryer to completely dry the tank. This step is critical, as any remaining moisture can affect the adhesion of the sealer. Ensure that the tank is completely dry by checking that there is no moisture or condensation inside. Aim for a temperature of 130 degrees F, as one source suggests.
Using a hair dryer will help speed up the drying process and ensure that all moisture is removed. It is important to be thorough during this step, as proper drying will affect the final result. Take your time and make sure the tank is completely dry before moving on to the next step of applying the POR 15 fuel tank sealer.

Pour in the entire can of POR 15 Fuel Tank Sealer
Before you pour in the entire can of POR 15 Fuel Tank Sealer, it is important to prepare your fuel tank. Firstly, ensure that your fuel tank is free from plastic parts, contamination, and is structurally sound. Remove any plastic components from within the tank, as the sealer does not adhere well to plastic. Next, clean the tank with POR-15 Cleaner Degreaser, mixing one quart of the cleaner with one quart of hot water to remove any gum, varnish, or sludge. Then, coat the tank with POR-15 Metal Prep to dissolve rust and etch the metal for better adhesion of the sealer. After these steps, drain and rinse the tank thoroughly with water, and let it dry completely.
Now, you are ready to pour in the entire can of POR-15 Fuel Tank Sealer. This product is a high-tech sealer formulated for metal surfaces, designed to be impervious to various fuels, including diesel, E10 ethanol, and high-alcohol content fuels. It acts as a liner, preventing rust, corrosion, and small fuel leaks. The amount of sealer you will need depends on the size of your fuel tank. For example, 8 fl oz is typically enough to coat the inside of a 6-gallon fuel tank.
After pouring in the sealer, ensure that all surfaces are coated adequately. Then, drain the tank for about an hour to remove any excess sealer. Finally, once the sealer has been applied and your tank is repaired, use fuel preservation and stabilizer to maintain your fuel system and avoid any "stale gas" issues.
Please note that it is essential to wear gloves during this process, and avoid getting the sealer on your bare skin. Additionally, ensure that you understand each product in your repair kit and how it works to achieve the best possible bond of the sealer to your tank.

Drain the tank to remove excess sealer
To drain a fuel tank to remove excess sealer, you can use one of several methods. One common method is to use a hose and a container to collect the fuel. Insert the hose into the tank and suck on the other end to start the flow of fuel, then transfer the fuel to the container. While this method doesn't require any specialised equipment, it carries some risk of inhaling toxic fumes, and fuel can enter your mouth, which is dangerous.
Another method is to use an air compressor. This process requires an air compressor, a fuel tank adapter, and a fuel line. Connect the fuel line to the tank adapter and the adapter to the air compressor. Then, start the compressor to force the fuel out of the tank.
You can also use a manual pump, which is a straightforward process. You'll need a manual pump, a fuel tank adapter, and a fuel line. Connect the fuel line to the adapter and the adapter to the pump, then start the pump to force the fuel out. Keep a container nearby to collect the drained fuel.
If you can find the drain plug on your fuel tank, you can also drain the fuel directly. Loosen the plug with a wrench, and fuel will start to drain out. Make sure to have a wide-mouthed container to catch the fuel.
For fuel-injected engines, you may be able to use the fuel line and pump to drain the tank. Disconnect the line at the engine and use it to fill your container. Keep in mind that fuel-injected engines typically turn off the fuel pump after 30 seconds if they don't detect pressure, so you'll need to turn the key off and back on to keep it pumping.
It's important to note that removing POR-15 fuel tank sealer can be challenging. While methods like aircraft stripper, citri-strip, grinding, or sanding may help, they may not be perfect and will likely require additional scraping. Sandblasting is recommended as the preferred method for removal.
