Steps to follow: 

Step 1: Remove the damaged gas tank from the mower and clean all the dirt attached to the gas tank. Clean the gas tank with liquid soap and warm water until the smell of the gasoline is properly removed. Rub the tank with alcohol to remove all the unwanted pieces of dirt. 

Step 2: Now use the box knife to remove all kinds of loose strings of plastic from the damaged area. Take the measurement of the damaged area. 

Cut the plastic bottle according to your measurement so that it can completely cover the damaged area. Always try to cut 1.5 times larger plastic pieces than the damaged area. Do not cut the plastic bottle just by looking or guessing with the naked eye. 

Step 3: When the patch material is ready, now it’s time for heating the things. In the time of heating, two things you need to care about.

  • Heat the damaged area from a distance so that the plastic never burns or produces smoke.
  • The mere goal should be to make the plastic flexible without melting it or losing the shape. 

Step 4: Now, take the heat gun and start heating the damaged area. Heat the damaged area from a distance to make it pliable. 

Step 5: When you see the place is slowly becoming flexible and feeling a little wet, just place the pre-prepared patch material in that place. Continue heating until the patch element becomes wet as well. Remove the heat gun and place it in a safe place.

Step 6: Take the painting spatula and apply light pressure in the heating area to remove any bubble from that area. Don’t put too much pressure because it ruins the shape of the tank. Wait for a while so that the patch element sticks well to the tank. 

Check the tank when the patch is cool. If you feel that the patch is thin, apply another patch again following the previous process.

Step 7: Clean the repair area with a paper towel. Now, fill the gas tank with gasoline to check the tank. Carefully inspect the tank to see if there are any leaks. If there is no leakage, then your tank is ready to hold the gasoline again.
