Necessary Tools

  • Clean towel or rag
  • Filtration mask
  • Safety Glasses
  • Jack Stands
  • Sandpaper
  • Gas tank repair epoxy putty compound
  • Rubbing Alcohol or other degreaser
  • Car jack
  • Vinyl or kitchen gloves


Phase 1 – Jack up the Vehicle

First, you need to lift the car to a height where you can easily insert jack stands underneath it. Now, you slowly lower the jack to maintain a height where you can easily get underneath the vehicle and perform the repairing task.


Phase 2 – Locate the Leak or Hole in the Gas Tank

Once you are under the gas tank, check it carefully to locate the source of leakage or small holes dripping gasoline.


Phase 3 – Sanding the Leaky Area

Now sand the holes using sandpaper. You need to cover an area of 1.5 to 2 inches around the hole.


Phase 4 – Wipe the Surface

After you are done sanding, use a degreaser to wipe the area with a towel. You can also use alcohol. Make sure all grime, dirt, and grease are cleaned away.


Phase 5 – Blend the Epoxy

For mixing the epoxy compound, the manufacturer’s manual will come handy. Use compounds from two different tubes to create a mixture and use it before it dries up. The instructions for mixing the compounds are usually written on the packet.


Phase 6 – Shape and Apply the Epoxy

Now, from the mixture, you cut a piece of about 1-1.5 inches. And, create a small shaped cone using the epoxy compound with a wider base at the bottom and a tip at the top.


Phase 7 – Press the Epoxy in the Hole

Next, you use the top of the cone to fill in the hole in the tank. Keep pressing the epoxy until it fills the hole or holes for good and use the remaining to smooth the sanded area. A little bit water can make the smoothening process easy.


Phase 8 – Fill the Tank with Gas

This is the last step in your gas tank leak repair job. Fill in the tank to the fullest, as you normally do. Once the tank is filled, look out for any signs of leakage. If you followed the above mentioned steps properly, the leak should be sealed for good and you can take credit for a successful gas tank leak repair job.
