What You'll Learn
Temporary fixes for small holes include epoxy or lead solder
Temporary fixes for small holes in a motorcycle fuel tank include epoxy or lead solder. Before applying either, it is important to prepare the tank by draining it of any fuel or other liquid. You should also clean the tank with lots of water to prevent severe injury, as gas tanks are highly flammable, even after cleaning.
Epoxy is a good temporary fix for pin holes made by rust. To apply it, pour the epoxy into the tank's fuel fill hole, cover the hole with plastic wrap, and secure it with a rubber band. Swill the epoxy around the tank for two minutes, then remove the plastic wrap and pour out the excess. Move the tank around to prevent epoxy from building up, then dry the tank upside down for five minutes. After one hour, use a pocketknife to scrape off any epoxy that has oozed onto the exterior. Let the tank cure for at least 24 hours, then test it for leaks by filling it with water.
Another temporary fix for small holes is to use lead solder. First, remove any paint at the leak site, down to the bare metal. Use a metal cleaner to prepare the surface, then make a small dent at the leak. Melt some lead (from fishing weights, bullets, or wheel weights) and pour it into the hole, letting it set.
While these temporary fixes can be effective, it is important to note that for larger holes, from punctures or deep rust, it is recommended to seek professional repair or replace the tank.

Welding can be used for small holes
Welding is a suitable method for repairing small holes in a motorcycle fuel tank. This technique is best applied to tiny pinhole-sized punctures. Before welding, it is important to clean the tank thoroughly with water and ensure that it is dry. It is also crucial to exercise caution during the welding process, as there have been reports of injuries caused by welding on tanks.
When welding, it is recommended to use very low heat to avoid damaging the surrounding material. For larger holes, it may be necessary to weld a thin piece of steel over the hole. This process can be made easier by creating new mounting ears and welding them in place, as this provides a stronger base for the repair.
It is worth noting that welding is not the only method for repairing small holes in a motorcycle fuel tank. Some people have successfully used products like JB Weld, a type of epoxy, to fill and seal small holes. However, it is important to read the instructions for JB Weld and similar products before use, as some formulations may not be gas-proof.
Additionally, an "old-school" repair method involves removing paint from the leak area down to the bare metal, using a metal cleaner to create a rough surface, and then making a small dent over the leak. You can then melt some lead (from fishing weights, bullets, or wheel weights) and pour it into the hole to create a patch. Once the lead has set, it can be filed down, sanded, filled, primed, and painted to restore the tank's appearance.
While welding can be an effective solution for small holes in a motorcycle fuel tank, it is important to consider the condition of the rest of the tank. If the tank is heavily rusted or damaged in other areas, a more comprehensive repair or replacement may be necessary.

Larger holes may require a professional repair or a new tank
While small holes in a motorcycle fuel tank can be patched using products like epoxy or JB Weld, larger holes may require a professional repair or even a new tank. This is because larger holes, often caused by punctures or deep rust, can be more challenging to fix and may need specialised equipment and knowledge to ensure a safe and effective repair.
If the hole in your fuel tank is more extensive than a pinhole leak or a small rust hole, it is essential to consider the risks and complexity of repairing it yourself. Fuel tanks are highly flammable, even after they have been cleaned and emptied, so working on them carries a significant safety hazard. It is crucial to work away from any sources of heat or flame to minimise the risk of injury or damage.
For larger holes, it may be more advisable to seek the expertise of a professional welder or a repair shop that specialises in fixing gas tanks. They will have the necessary skills and equipment to handle the repair safely and effectively. This option may be more costly and time-consuming, but it can provide a more durable and reliable solution.
In some cases, the extent of the damage or the condition of the tank may make it more practical and economical to simply replace the entire tank. This is especially true if the tank is severely rusted or has multiple issues. While purchasing a new tank can be an additional expense, it can save you from the hassle and potential dangers of repairing a heavily damaged tank.
Ultimately, the decision to repair or replace a fuel tank with larger holes depends on factors such as your budget, the time and effort you're willing to invest, and the overall condition of the tank. If you are unsure about the best course of action, consulting with a professional can provide you with guidance tailored to your specific situation.

Drain the tank and clean it thoroughly before attempting any repairs
Before repairing a hole in your motorcycle fuel tank, it is important to drain and clean the tank thoroughly. This will ensure that no debris or residue remains that could interfere with the repair process. Here is a step-by-step guide to draining and cleaning your motorcycle fuel tank:
Step 1: Drain the Fuel Tank
Start by closing the petcock, if you have one, and lifting the fuel tank off. Alternatively, you can attach a hose to the petcock and place the other end of the hose into a gas can. Open the petcock to drain the fuel into the gas can. If you don't have a petcock, you can try siphoning the fuel out using a hose or vinyl tube. Place one end of the hose into the fuel tank and the other end into a gas can, then blow into the hose to create a siphon and drain the fuel.
Step 2: Clean the Fuel Tank
Once the fuel tank is drained, it's important to clean it thoroughly. Use a metal cleaner to remove any dirt, grease, or rust from the tank. Make sure the cleaner has some "scuff" to it to create a rough surface for repairs. Pay close attention to the area around the hole and ensure it is clean and dry before proceeding to the next step.
Step 3: Inspect the Fuel System
Before repairing the hole, it's a good idea to inspect other components of the fuel system, such as the fuel filter and carburetor. Clean or replace the fuel filter if necessary. If you experience issues with the carburetor, consider disassembling and cleaning it thoroughly before reassembling.
Step 4: Prepare the Repair Surface
With the tank drained and clean, you can now focus on the hole. Depending on the size of the hole, you may need to weld it shut or use a patch. For small holes, you can use a product like JB Weld or a specially designed fuel-resistant epoxy to fill and seal the hole. For larger holes, you may need to weld a thin piece of steel over the hole first and then use body filler to restore the tank to its original shape.
Remember to work in a well-ventilated area and wear appropriate safety gear when handling chemicals and power tools. Always refer to the manufacturer's instructions or seek professional assistance if you are unsure about any aspect of the repair process.

Test the tank for leaks after repairing
Once you've repaired a hole in your motorcycle fuel tank, it's important to test it for leaks to ensure the repair was successful and safe. Here's a step-by-step guide to testing your fuel tank for leaks:
Start by ensuring the tank is completely dry and free of any fuel or vapour. This step is crucial for safety, as welding or using other repair methods on a tank with fuel residue can create a fire hazard. Drain the tank into a safe-disposal fuel container, and use something like kitty litter to absorb any excess fuel that may spill over.
Next, you'll need to remove the fuel line. Carefully depress the clamp and gently pull the fuel line off the nipple of the gas tank. Take your time with this step to avoid any accidental spills or sprays of fuel. Now, you can proceed with the pressure test.
For the pressure test, you'll need to refer to a guide or video tutorial specific to the type of motorcycle you own. The process may vary slightly depending on the make and model of your bike. Generally, the pressure test involves checking for any leaks, pinholes, or cracks in the welds or seams of the gas tank. This step is essential to ensure the safety and longevity of your repair.
If you identify any issues during the pressure test, you may need to repeat the repair process or seek professional help. It's important to be thorough during this stage, as a small leak can lead to fuel leakage and potential safety hazards while riding.
Finally, once you're satisfied that your fuel tank is leak-free, you can proceed with any desired cosmetic steps, such as painting the tank to match your motorcycle's style. Remember to refer to your motorcycle's user manual or seek expert advice if you're unsure about any part of the process.
