Fixing a dirt bike fuel tank can be a simple process, but it depends on the type of damage and the material of the tank. If you have a leaky metal gas tank, for example, you can use a product like Permatex 4 Minute Multimetal Epoxy to bond and repair cracks or holes. For plastic tanks, a small soldering iron can be used to melt the plastic and seal the crack, followed by the application of plastic glue for reinforcement. If your fuel tank is beyond repair, you may need to replace it with a new one, or opt for a temporary fix like using DEI Quick Fix Tape to create a waterproof seal.

What You'll Learn
Fixing a leaky fuel tank
Once the tank is drained, you can begin repairing the leak. If the tank is plastic, you can use a small soldering iron to melt the plastic and seal the crack. You can then apply a plastic glue kit to the repaired area as a backup. If the tank is metal, you can use a product like Permatex 4 Minute Multimetal Epoxy, which bonds to most metal surfaces and allows for sanding, drilling, and threading once cured. For a quicker fix, you can use a product like DEI Quick Fix Tape, which provides a waterproof permanent seal for cracks or holes in the tank.
If the leak is coming from the fuel line rather than the tank, you will need to replace the damaged section of the hose. First, turn off the fuel petcock to prevent gas from spilling out. Then, use pliers to remove the clips from the fuel tank and carburetor. Finally, replace the damaged hose with a new one, securing it with the appropriate clamps.
It is important to regularly inspect your dirt bike's fuel line for any signs of damage or wear, as this is a common cause of performance issues and engine failure. Incorporating a fuel line check into your regular maintenance routine can help prevent leaks and other problems.

Removing the fuel tank
Firstly, it is important to drain the fuel tank. This can be done by riding the bike until the gas runs out. If this is not possible, the remaining fuel should be drained by removing the fuel line. Locate the black rubber tube connecting the gas tank to the motor and remove the clip. Use pinch pliers on the tube to prevent fuel spillage and drain the fuel into a suitable receptacle.
Next, remove the seat of the dirt bike to access the fuel tank strap on the subframe. Remove the strap and any radiator shroud bolts tightened to the radiator, as well as the bolt by the steering head. It is not necessary to remove the bolts tightened into the gas tank.
With the above steps completed, the fuel tank can now be easily removed from the bike. Be careful when lifting the tank out, as there may still be a small amount of fuel left inside. It is recommended to place the tank in a safe area away from any open flames or sparks.
Once the fuel tank is removed, you can proceed with the necessary repairs or maintenance. It is important to follow the correct procedures and safety precautions during this process. Always refer to the dirt bike's user manual or seek expert advice if you are unsure about any steps.
Finally, when reinstalling the fuel tank, ensure that all connections are secure and properly tightened to prevent fuel leaks. This includes checking the fuel line connections and ensuring the tank is firmly attached to the subframe.

Replacing the fuel line
To replace the fuel line on a dirt bike, you'll first need to drain the fuel tank. The best way to do this is to ride the bike until the tank is empty. If this isn't possible, you can remove the fuel line and drain the remaining fuel into a receptacle. Be sure to do this outside, not in your garage. To remove the fuel line, look for a black rubber tube coming from the gas tank and feeding into the motor. Remove the clip and work the tube free using pinch pliers.
Once the fuel tank is drained, turn off the fuel petcock to prevent gas from spilling out when you remove the fuel line. You can then remove the clips from the fuel tank and carburetor using pliers. If your bike uses a ""remote" petcock, you'll need to remove the fuel line at the petcock and use pinch pliers to prevent fuel from spilling.
The fuel line is usually attached with pinch clamps or screw clamps. If you have screw clamps, you'll need a screwdriver, typically a Phillips head or Allen wrench (hex socket). Loosen the screws and free the clamps. For pinch clamps, you'll need pliers unless you have very strong hands. A third option is crimped-on hose clamps, which will need to be cut off using a clamp kit.
After removing the old fuel line, attach the new fuel line using the appropriate clamps and screws. Be sure to check your owner's manual for any special tools or instructions specific to your bike model.
It's important to regularly inspect your fuel line for any signs of damage or wear. Old, cracked, or damaged fuel lines need to be replaced. Kinks in the fuel line can also cause issues and may require replacement if they don't work out. Additionally, it's recommended to use high-quality fuel and add a stabilizer when storing your dirt bike to prevent the fuel line from gumming up.

Repairing a metal gas tank
Dirt bike fuel tanks are usually made of plastic, but some older bikes have metal tanks. Metal gas tanks can be repaired, but it is a complex process that requires expertise and caution.
The first step is to drain the fuel tank. This is done by removing the fuel line and letting the remaining gas pour into a receptacle. It is important to perform this step outdoors to avoid spilling fuel. Once the tank is empty, it can be removed from the bike by unscrewing the bolts and detaching the fuel pump. With the tank removed, the next step is to identify the leak. Common areas for leaks include places where dirt or debris can pool up and hold moisture, or the tank seam where the two halves are connected.
Once the leak is located, the area must be prepared for repair. This includes sanding the rusted areas with grit sandpaper to smoothen the surface and improve paint bonding. The tank should then be cleaned with soap and water or filled with argon gas to remove any remaining fuel or debris. After the tank is clean and dry, a sealant or epoxy can be applied to the leaking area. It is important to use a product specifically designed for fuel tank repair, such as the Permatex 4 Minute Multimetal Epoxy, which bonds to most metal surfaces and allows for sanding, drilling, and threading after curing.
Another method for repairing a metal gas tank is to use a welding technique such as brazing or soldering. However, this requires extreme caution as the fumes from welding can be explosive. It is recommended to run exhaust fumes through the tank for about an hour and let it air out for several days before attempting any welding repairs. Additionally, most professional welders prefer TIG welding for gas tanks, as it minimizes distortion.
For small cracks or holes, a quick fix option is to use a self-curing tape such as DEI Quick Fix Tape, which provides a waterproof permanent seal. Tech-Patches are another option for repairing small cracks. They are made from a flexible polymer that has excellent resistance to water, oil, regular gas, weather, dirt, grease, salt, and common chemicals.

Fixing cracks in a plastic tank
Fixing cracks in a plastic dirt bike fuel tank can be done in a few different ways. Firstly, it is important to drain the fuel tank before attempting any repairs. This can be done by removing the fuel line and letting the fuel pour into a receptacle.
One method for repairing cracks in a plastic tank is to use a soldering iron to melt the plastic and seal the crack. This method can be effective and relatively inexpensive, but it may not work for larger cracks. Before using the soldering iron, it is recommended to spray the area with a contact cleaner to remove any gas or oil residue. After using the soldering iron, you can also apply plastic glue to the repaired area for added strength.
Another option is to use a plastic repair kit, which can be an effective way to fix small cracks and holes. These kits typically include a two-part epoxy that is mixed and applied to the crack. It is important to prepare the surface properly before applying the epoxy, by roughening the surrounding area and V-ing out the crack.
Additionally, plastic welding has been mentioned as a possible solution. This method can provide strong and durable repairs, but it may be more expensive and require specialized equipment. Plastic welding can be done with different types of welders, such as nitrogen plastic welders, hot air welders, or airless welders. The choice of welder will depend on factors such as budget and desired appearance of the repair.
For a quick and temporary fix, self-curing tape can be used to provide a waterproof seal over small cracks. This method is not recommended for larger cracks or as a long-term solution.
