What You'll Learn
Removing rust from the fuel tank
Firstly, you'll need to gather the necessary materials and safety equipment. This includes a gas tank, which should be removed from the vehicle and placed in a well-ventilated outdoor area for your safety and to avoid damaging other components. You will also need safety gear such as heavy rubber gloves and eye protection to shield yourself from harmful chemicals and rust particles.
Next, you'll want to inspect the tank for any fuel varnish, residue, or gunk. If present, these will need to be thoroughly cleaned out. A running garden hose can be used to rinse the tank, ensuring that all varnish is removed. You may need to repeat this step if traces of varnish remain. It is crucial to ensure that the tank is free of all fuel varnish before proceeding.
Once the tank is clean, you can move on to the rust removal process. One effective method is to use Muriatic Acid, which can be purchased from hardware or building supply stores. It is important to follow the proper handling instructions on the label and never use undiluted Muriatic Acid inside the tank. "Slosh" the diluted acid around on all internal surfaces, ensuring that at least one opening remains uncapped for pressure release. Continue this process until all rust is removed, and the tank has a uniform gray appearance.
Another method for removing rust is through electrolytic means. This involves using a sacrificial anode made of steel or iron, a battery charger, and a suitable container, such as a bucket. Attach the negative lead from the battery charger to the tank and the positive lead to the sacrificial anode. Fill the tank with water and Arm & Hammer Super Washing Soda, ensuring the anode does not come into contact with the tank. Turn on the charger and let it run for several hours. Between sessions, clean the anode by knocking off accumulated rust and sanding it down.
After successfully removing the rust, it is important to neutralize any remaining acids and prepare the tank for sealing. This can be done by "sloshing" Acetone on all internal surfaces, then pouring the contents back into the original container. Repeat this step with fresh Acetone to ensure all traces of acid are gone. Proper disposal of used Acetone is crucial, and it should be handled in accordance with local laws.
Finally, ensure that the tank is completely dry before proceeding with the sealing process. Forced ventilation can aid in drying and prevent the sealer from puddling. Inspect the tank once more to confirm that no rust remains, and you are now ready to proceed with sealing your fuel tank.

Selecting the appropriate sealant for a plastic gas tank is essential. Some recommended options include:
- Super glue (Cyanoacrylate): Super glue is highly resistant to gasoline and ethanol. It can penetrate small cracks and has strong bonding properties, but it may cause discolouration or brittleness around the repaired area.
- SealAll: SealAll has been successfully used to seal plastic tanks, but some users have experienced recurring leaks.
- Soldering iron: Plastic welding with a soldering iron is an effective method. You can use shavings or rods of similar plastic to fill in gaps and create a strong seal.
Step 4: Seal the Tank
Once you have chosen the appropriate sealant, carefully follow the manufacturer's instructions for application. Ensure proper ventilation during the sealing process to prevent the inhalation of fumes.
Step 5: Curing and Drying
After applying the sealant, allow the tank to cure and dry completely. This process may take up to 48 hours or more, depending on the sealant used and the ambient temperature. Refer to the sealant's instructions for specific curing and drying guidelines.
Step 6: Final Inspection
Before refilling the tank with gas, inspect it carefully to ensure that the sealant has dried properly and that there are no signs of ongoing leaks.
Remember to exercise caution and wear protective gear throughout the process to ensure your safety and the effectiveness of the sealing procedure.

Using a gas tank sealer kit
There are several gas tank sealer kits available on the market, such as the Eastwood Gas Tank Sealer Kit, the POR-15 Fuel Tank Sealer Kit, and the KBS Coatings Auto Fuel Tank Sealer Kit. Each kit will come with its own specific instructions, but there are some general steps that you can follow when using a gas tank sealer kit.
First, you need to prepare the surface of the tank. This includes draining and removing the tank from the vehicle, washing it with hot soapy water, and removing any valves, sending units, petcocks, and internal filters. It is important to ensure that the tank is absolutely dry and free of water before applying the sealer, as even a small amount of water can damage the sealer's adhesion.
Next, you will need to clean and prepare the tank for sealing. This may involve using a metal wash or a degreaser to remove any fuel varnish, old sealers, or contaminants from the tank. You may also need to use an acid treatment or a product like POR-15 Metal Prep to etch the tank and improve adhesion. It is important to follow the instructions provided with your specific kit to ensure that you are using the correct products and techniques for your particular tank and sealer.
Once the tank is clean and prepared, you can apply the sealer. Follow the instructions provided with your kit to mix the sealer with water or another solution, if necessary. Then, pour the sealer into the tank and work it around the inside of the tank, ensuring that all internal surfaces are coated. You may need to slowly rotate the tank in all directions to get an even coating.
After coating the tank, you will need to let it cure and dry completely. This may take up to 48 hours, depending on the product and the temperature. It is important to provide forced ventilation during this time to prevent the sealer from reflowing and puddling. Once the tank is dry, you can inspect it to ensure that the sealer has been applied properly and that there are no puddles or uneven spots.
Finally, you can reassemble the tank and fill it with fuel. It is recommended to use a fuel preservation and stabilizer product to keep your fuel system in proper working order and avoid any future issues.

Selecting the right fuel hose type
When selecting the right fuel hose type, there are several factors to consider. Firstly, it is crucial to determine the thread type of the component you are purchasing and ensure it matches the thread type of the fuel hose. Most fuel filters, pumps, and tank connections have female NPT or NPTF ports, which require a male hose barb fitting. Brass or stainless steel is typically used for these components.
Secondly, consider the type of fuel your vehicle uses. Not all fuel hoses are compatible with all types of fuel. For example, if you are using diesel, choose a hose marked "diesel". If you are using high-ethanol fuel, ensure the hose can handle alcohol-blended fuels. Ethanol blends can dry out rubber hoses, making them brittle and prone to leaks, so it is important to select a hose that can handle modern fuel additives.
Thirdly, assess the location of the fuel line run. Determine if it will be above or below deck. Above deck refers to an open setup, such as an outboard engine connected to an above-deck tank. Below deck includes confined compartments, and in these cases, you must use an A1 fuel hose, which offers the highest fire resistance and the least permeability. A2 fuel hose can be used above deck but has lower fire resistance. B-type fuel hoses are more permeable and suitable for less volatile fuels like diesel.
Additionally, consider the working pressure of your fuel system. SAE 30R6 and 30R7 hoses are designed for systems rated at 50 PSI or less, while SAE 30R9 hoses are for EFI systems with working pressures of 100 PSI and above. Submersible hoses are specifically designed for use in fuel tanks and are necessary for in-tank fuel pump modules to prevent the fuel from breaking down the hose.
Lastly, be mindful of emissions regulations. The state of California has strict emissions standards, and a CARB-certified fuel hose is recommended for better fuel economy and resistance to seepage. For marine applications, use a USCG-marked hose to ensure fire resistance.

Sealing fuel fittings and fuel lines
When it comes to sealants, it is important to consider their chemical resistance to fuel (diesel or gasoline) or oil running through the line. While some backyard mechanics may suggest using regular gas-resistant Teflon tape, this is not recommended as it can break free and cause clogging issues. Instead, liquid or paste-type thread sealants are preferable as they are less likely to cause issues with sensitive components. Form-a-gasket No. 3, for example, offers solvent resistance to gasoline, especially in modern engines with injectors.
Another critical factor is the location of the fuel line run. This determines the appropriate fuel hose type to be used. If the fuel line is above deck, it is typically connected to an outboard engine and an above-deck tank. Below-deck fuel lines include those running through confined compartments. There are four grades of fuel lines: A1, A2, B1, and B2. A1 fuel hose, offering the highest fire resistance and lowest permeability, is the recommended choice for below-deck high-pressure applications. B-type fuel hoses, on the other hand, are more permeable and suitable for less volatile fuels like diesel.
When assembling fittings, it is important not to over-tighten them as this can stretch the threads and lead to leaks. A properly formed double flare on the tubing combined with an inverted flare fitting will seal effectively. Additionally, AN-type fittings and NPT fittings are known to seal well. For NPT fittings, Teflon tape or paste is often required as it acts as a lubricant and helps seal the joint. However, it should not be applied to the first three threads from the end.
