many lawnmowers use gasoline engines. This type is more efficient than electric, especially for 3 or more acres of lawns. If you are using gasoline lawn mowers, you need to know what exactly a plastic gas tank is.
There are many problems with plastic gas tanks when using a lawnmower. It can break, crack, split, be damaged, or leak somewhere. So instead of replacing it for $ 200 or more, you can fix it for pennies.
Repairing plastic is actually very easy to do, but it takes patience and attention to detail. This is because due to prolonged use or accidents, plastic gas tanks can be damaged, broken, leak, crack or split. And you know that a damaged gas tank loses its ability to hold gasoline and your lawnmower becomes useless to you. Taking care of the materials is key to the process as they need to be clean and organized. You need to focus on your homework because time is a problem when fixing plastic items like this.
There are many different ways for people to try to fix a broken plastic gas tank, but if you’re looking for something permanent (rather than a temporary fix), read on to find out how to fix your gas tank. plastic gasoline!
The following materials will be needed to help you effectively and successfully repair the plastic gas tank:
Once you have the tools, the next step is to clean the gas tank. The reason? Any foreign object such as dust or grease can interfere with the welding process. Remove the tank (if possible) or use a fuel pump to completely drain the tank. Be aware that even a little fuel, in contact with heat, can cause dangerous explosions.
When you remove it, clean it with dish soap and water until it no longer smells of fuel. Then use a few drops of an alcoholic solvent such as acetone and scrub thoroughly to ensure optimal cleaning. Also, clean the patch material to make sure the two stick together completely when applying heat.
With the box knife, take your time to smooth out the damaged area as much as possible. Remove plastic fingers or rough areas or edges as they can promote cracking and cracking. Don’t be too harsh, but apply gentle force to smooth the area.
Now take a close look at the area to get an almost perfect idea of the patch length required. Since my neighbor is a professional, it didn’t take long for him to get the job done. However, if you are doing this for the first time, it is best to get a tape measure or scale.
In addition, it is recommended to cut a patch slightly larger than necessary. This will allow some room for error and you will still be able to fuse the excess with the tank body.
Start by heating the damaged area with the heat gun. Make sure to keep it out of the way and apply the heat to a larger area, rather than a concentrated spot to avoid burning or melting. When you notice that the plastic has become flexible and appears to be “wet,” move the patch material into the heat gun airflow. This will simultaneously mold the patch and the damaged area.
Observing similar humidity, lay the patch on the required area and slowly move away from the heat gun. Using the spatula, gently sweep the patch to remove any air bubbles. Again, don’t apply too much pressure.
A little advice: practice the “drop” beforehand to obtain a perfect alignment. Once in place, you will not be able to remove the patch.
While the fused pieces are still cooling, gently clean the adjacent areas. The flat tip of the screwdriver will be useful for specific corners and places. However, don’t rush to put on water or wet towels. As the plastic cools, the materials coalesce to cover the damage.
If the patch material is too thin, repeat the process two or three times until you reach the desired thickness. In addition, thinner patch materials make the repair more controllable. But make sure each layer is completely cool before you can apply more heat. As this forms a molecular bond between both materials, the patch becomes permanent and does not lose its “tack” as quickly as in the case of glue or tape.
Take the paint spatula and apply light pressure to the heating area to remove any bubbles from that area. Don’t apply too much pressure because it ruins the shape of the tank. Wait a moment for the patch element to adhere well to the tank.
Check the tank when the patch is cold. If you feel the patch is thin, reapply another patch following the above process.
Clean the repair area with a paper towel. Now fill the gas tank with gasoline to make sure the tank. Carefully inspect the tank for leaks. If there are no leaks, then your tank is ready to hold gasoline again.
Things to consider
While the gas tank repair process may seem like a lot of effort, it is not. You just need to be prepared for it. That is why you should consider these tips:
The repair process can take anywhere from 10 minutes to 1 hour or a little longer.
Timing is of the essence when it comes to fixing the tank. Since you will be using epoxy, you will need to act quickly to prevent the plastic from drying out in the middle of the operation.
You will use epoxy to repair the tank. This adhesive can melt into plastic as you work with it. Don’t worry when this happens, it is typical.
This solution should be permanent unless you make a mistake. So be careful and pay attention to the job at hand.
You don’t need to buy a new gas tank if it’s a little broken, thanks to the above-mentioned methods that can be used to solve your problem. Not only does the gasoline leak drain the fuel faster, it can also be dangerous as it is highly flammable. Therefore, it is recommended to fix it as soon as possible. Also, don’t forget to wear protective gloves to protect you from unnecessary burns and cuts. Safety glasses should also be worn to protect your eyes from toxic fumes. All tools used in the process must be kept out of the reach of children to avoid accidents.
