Removing a dent from a fuel tank can be a tricky process, and there are many different methods that can be used. Some methods include using a Pops-a-Dent kit, welding a rod to the dent, using a dent puller, or even filling the tank with water and freezing it. Each method has its own advantages and disadvantages, and the best approach may depend on the size and location of the dent, as well as the thickness of the tank material.

What You'll Learn
Using a Pops-a-Dent kit
The Pops-a-Dent kit has received mixed reviews. Some people have found it to be effective, even on dents that are close to the edges or corners of the fuel tank. They were surprised that the hot glue held well and were pleased with the results, especially since this method does not require welding.
However, others have found that the Pops-a-Dent kit did not work for them, even after trying different approaches like warming up the glue gun and scuffing the paint. They speculated that the glue may not hold if the dent is too close to the edge or corner of the fuel tank, as these areas are stronger and more resistant to the pulling force.
Overall, the Pops-a-Dent kit can be a good option for removing dents from a fuel tank, but it may not work in all situations, especially if the dent is too severe or located in certain areas of the tank. It is worth trying, as it is a relatively inexpensive option, and users have had success with it.

Welding a rod to the dent
Welding on a fuel tank is extremely dangerous, and it is highly recommended to seek professional help. If you insist on doing it yourself, you must take extreme precautions. Before welding, the tank must be purged of any fuel vapours to prevent explosions. One way to do this is to fill the tank with water to displace the vapours. However, some sources claim that filling the tank with water is not a good idea, as it can be difficult to weld and may not be reliable.
Another method to purge the tank is to fill it with exhaust fumes or inert gases like carbon monoxide, nitrogen, argon, or CO2. This will prevent sparks inside the tank from causing an explosion. You can also use a detergent and water mixture to wash out the tank several times.
Once the tank is purged and cleaned, you can begin the welding process. To pull out a dent, you can weld a rod or rivet to the dented area and then pull it out. You will need to grind off the rod and fill the remaining space with putty or Bondo.
It is crucial to exercise extreme caution when welding on a fuel tank, as the consequences of improper procedures can be severe. If you are unsure or uncomfortable with the process, it is always best to seek professional help or consider alternative repair methods.

Using a hammer and crowbar
Firstly, assess the dent. Understand the extent of the damage by checking if it is shallow or deep and if the paint is damaged. This step is crucial as it helps you choose the right approach and tools. A clean surface is essential, so make sure to clean the area around the dent using soap and water to remove any dirt or grease.
Next, prepare the fuel tank by draining it completely. This is an important safety precaution as you do not want to risk any fuel residue igniting during the repair process.
Now, you can begin the dent removal process. Take the crowbar and insert it into the fuel tank. Use the hammer to gently tap on the crowbar, applying pressure to the dent, and try to punch out the dent. Be careful not to use too much force as you don't want to cause further damage to the tank.
After removing the dent, you will likely need to smooth out the area. A material like Bondo, a type of body filler or putty, can be used to fill in any remaining imperfections and create a smooth surface.
Finally, once the filler has dried, sand the area until it is flush with the surrounding surface. You can then apply touch-up paint and a clear coat for protection and to restore the fuel tank to its original appearance.
Remember to take your time and work carefully to avoid any potential hazards or further damage to the fuel tank.

Freezing water inside the tank
One method for removing a dent from a fuel tank is to use the freezing water method. This involves pulling the tank from the bike, filling it with water, and then putting it in the freezer. As the water freezes, it will expand and push out the dent. The excess water should escape through the gas port. This method has been suggested on forums for Harley Davidson bikes and is said to work on headers, so it should work on a tank as well.
It is important to note that this method may take multiple tries to work, and it is crucial to be cautious and not freeze the tank for too long, as this could rupture or split the sheet metal. The spot with the dent is the weakest point and will be further weakened by flexing it back out. One suggestion is to fill the void with sand first, pack it in well, and then add water and freeze.
Before attempting any dent removal method, it is important to clean the tank thoroughly. One way to do this is by filling the tank with hot water, adding about a 1/4 cup of dish soap (specifically Dawn), shaking the tank vigorously, and then rinsing with water until no more soap is present. This will remove any traces of gas from the tank.
After the tank is clean, some people suggest using a stud gun to weld pulling studs onto the dent, which can then be used to pull out the dent. This method is used by professionals and can help to remove gas fumes, making for a better paint job. However, welding on a gas tank is dangerous, and it is crucial to take proper safety precautions to avoid explosion or injury.
Another method to consider is using compressed air with water in the tank. This method involves applying pressure with water and air, and then running the air for some time to dry the tank. However, it is important to note that this method may not be suitable for large or deep dents.

Using a glue gun
Firstly, you need to build a wooden slide hammer. To do this, you will require a large 1/2" drive socket, a long wood or sheetrock screw, a fender washer, and some glue. Slide the socket over a dowl and secure one end using the washer and screw. This end will act as the thrust force.
Next, you will need to glue the free end of the homemade slider to the dented area of the fuel tank. Ensure that you place the end of the slide hammer as close to the centre of the dent as possible. Use hot glue for this step, and allow it to cool for around 15 seconds.
Once the glue has cooled, grasp the socket and smack it against the fender washer. This action will create a pulling force, hopefully pulling out the dent.
Afterwards, you can use floss to remove the glue, and a hair dryer to melt any remaining glue off the tank.
This method is not always successful, and it is important to note that glue guns can sometimes do more damage than the original dent, especially if the metal of the tank is too thick. For deeper dents, it is recommended to seek professional help or consider other methods such as welding or using a dent puller.

Frequently asked questions
You can try using an old inner tube to pop out a shallow dent in your fuel tank. This method may not work in all situations, but it is worth trying before spending money on repainting your vehicle.
You can weld a rod into the dented area and then pull the dent out. Before welding, you must purge the tank using an inert gas like CO2, Argon, or Nitrogen to remove any fuel and oxygen. After welding, you will need to grind off the rod, apply body filler, and repaint the tank.
Yes, there are several alternative methods to remove dents from a fuel tank. Some of these include using a Pops-a-Dent kit, hot glue and a puller, dry ice, or a dent puller without drilling holes. It is important to note that some of these methods may not work for all types of dents or fuel tanks.
