JB Weld is a popular epoxy adhesive used for repairing fuel tank leaks. While some users have reported success in using JB Weld to repair plastic fuel tanks, others have experienced issues with adhesion and durability. Gas tanks are often made of HDPE (high-density polyethylene), a material to which JB Weld does not effectively adhere. However, some users have found that using a combination of screws, washers, and JB Weld can create a temporary solution for plastic fuel tank leaks.

What You'll Learn
JB Weld is not recommended for polyethylene tanks
One user on BobIsTheOilGuy.com shared their experience attempting to use JB Weld on a plastic fuel tank. They noted that while the epoxy patch held up, it was not a permanent solution and they would need to get a different tank. Another user on the same website suggested that plastic welding or a product called SealAll might be a better option for repairing a plastic fuel tank.
Reviews of JB Weld's TankWeld Gas Tank Repair product on Amazon are mixed. While some customers found that it worked well to seal leaks in their plastic gas tanks, others reported poor adhesion. One customer noted that the product hardened quickly but did not adhere to their fuel tank, even after preparing the area.
Given the varied experiences and the fact that JB Weld specifically states that their product does not adhere to polyethylene, it is not recommended for use on this type of plastic fuel tank. Alternative methods, such as plastic welding or using a different adhesive product, may be more effective for repairing leaks in polyethylene tanks.

JB Weld as a temporary fix
JB Weld is an epoxy adhesive that can be used to temporarily fix a plastic fuel tank leak. While it is not recommended as a permanent solution, it can be an effective temporary repair to stop a fuel leak and get you to a safe spot.
To use JB Weld as a temporary fix, follow these steps:
- Clean and prepare the area around the leak, ensuring it is free of any debris or residue.
- Mix the JB Weld epoxy according to the manufacturer's instructions. It is hand-mixable and will form an even colour when properly mixed.
- Apply the mixed epoxy to the leak, ensuring it covers the area completely.
- Allow the epoxy to harden and cure. This may take anywhere from a few minutes to a few hours, depending on the product and environmental conditions.
- Once hardened, you can drill a hole for a screw to provide additional support, if needed.
It is important to note that JB Weld may not adhere well to certain plastics, such as HDPE (high-density polyethylene), commonly used for fuel tanks. Therefore, it is essential to prepare the surface thoroughly and follow the manufacturer's instructions for the best results. Additionally, some users have reported that the epoxy can become sticky over time, so it is not recommended as a long-term solution.
As a temporary fix, JB Weld can be a quick and easy solution to stop a fuel leak and get your vehicle back on the road. However, for a more permanent and reliable repair, it is recommended to seek professional help or consider purchasing a new fuel tank.

JB Weld Tank Weld Gas Tank Repair
JB Weld Tank Weld is a fuel and metal tank repair kit designed for permanent or temporary repairs for metal and fuel storage containers. It can be used to repair leaks caused by cracks of up to 4" and holes with a diameter of up to 1/4". The kit is not recommended for plastic repairs or for use with polyethylene or polypropylene plastic parts.
JB Weld Tank Weld is hand-mixable, steel-reinforced, and non-rusting. It forms an industrial-strength polymer compound that can be used to repair, patch, and rebuild steel components. It is also oil-resistant, sandable, and drillable. It cures to a dark grey colour and is rated to have a lap shear strength of 4000 PSI. It can withstand temperatures of up to 350°F (176.6°C) and is resistant to harsh chemicals, including petroleum and hydraulic fluid.
To use JB Weld Tank Weld to repair a gas tank, the first step is to clean the area around the leak with sandpaper, covering a few inches around it. This removes any paint, rust, or grime and gives the epoxy something to adhere to. The area should then be sprayed with a cleaner and wiped down. The next step is to cut off an amount of SteelStik that will cover the repair. The SteelStik should be kneaded to mix the two colours until they form a uniform dark grey. After mixing, the area to be repaired should be cleaned and wiped dry once more. The putty can then be pressed into the centre of the hole and worked flat against the tank to ensure the hole is sealed.
While some customers have reported that JB Weld Tank Weld bonded perfectly to their fuel tank, others have stated that the adhesion was poor and that it did not adhere to plastic gas tanks. Therefore, it is important to note that results may vary, and it may be worthwhile to consider other repair options if JB Weld Tank Weld does not meet your needs.

JB Weld as an epoxy patch
JB Weld is an epoxy patch that can be used to repair leaks and patch holes and cracks in a variety of materials, including some plastics. It is important to note that JB Weld will not adhere to all plastics, specifically polyethylene and polypropylene. However, it has been used successfully to repair fuel tanks, which are often made of high-density polyethylene (HDPE).
When using JB Weld as an epoxy patch, it is important to follow the proper steps to ensure a strong and durable repair. First, it is important to clean and prepare the surface to be repaired. This may involve cleaning the area with a suitable cleaner and scuffing it up to create a rough surface for the epoxy to adhere to.
Once the surface is prepared, the JB Weld epoxy can be mixed and applied to the repair area. It is important to work quickly as JB Weld has a fast setting time of around 20-25 minutes. After mixing, the epoxy will form a polymer compound that can be molded or used to fill holes and cracks.
Once applied, the JB Weld will need time to cure. The functional cure time for JB Weld is typically around 2-3 hours, after which it will be strong and durable. After curing, the repaired area can be sanded, drilled, or painted as needed.
It is important to note that while JB Weld can be an effective repair solution, it is not recommended for all situations. In the case of fuel tanks, a more permanent solution, such as a metal weld or professional plastic welding, may be preferable to ensure the safety and integrity of the repair. Additionally, it is always important to consider the specific materials involved and whether JB Weld is suitable for the type of plastic being repaired.

JB Weld for metal tanks
JB Weld is an epoxy putty that can be used to repair leaks in automotive fuel tanks. While JB Weld is not recommended for plastic repairs or for use with polyethylene or polypropylene plastic parts, it is suitable for repairing metal fuel tanks.
The TankWeld™ kit by JB Weld is designed for permanent or temporary repairs of metal and fuel storage containers. It can be used to repair leaks caused by cracks of up to 4 inches and holes with a diameter of up to a quarter of an inch. The epoxy is hand-mixable, steel-reinforced, and non-rusting. After mixing, it forms an industrial-strength polymer compound that can be moulded into shapes or used to build up, patch, and repair steel components. It sets in 5 minutes and fully cures in 1 hour, curing to a dark grey colour. It has a tensile strength of 900 PSI and a lap shear strength of 4000 PSI. It will also withstand temperatures of up to 350°F (149°C) and intermittent temperatures of 450°F (232°C).
JB Weld can be drilled, tapped, machined, ground, filed, and painted once cured. It is also chemical-resistant against petroleum, hydraulic fluid, and many other harsh chemicals when fully cured. It is NSF Certified and safe for contact with potable water.
Some customers have reported that JB Weld works well for repairing fuel tanks, while others have noted that it does not harden fast enough and may crack easily. It is important to note that JB Weld is not a weld, but an epoxy patch, and may not be a permanent solution for repairing fuel tank leaks. For a more permanent solution, a real metal weld or professional plastic welding may be required.
