How to Repair Fuel Tanks

If you have a fuel tank that needs repairs, you are losing money and can possibly be facing a fire hazard. Leaking tanks need to be reported as soon as they are found. Fortunately, fuel tanks can be repaired relatively easily with just a few materials.

Acetone
Empty container
Masking tape
Putty
Plastic container
Epoxy
Plastic wrap
Rubber band
Knife

Instructions

- 1
  Remove any remaining fuel out of your tank. Drain it and then add 1 pint of acetone. The acetone cleans out the inside of the tank and is also a solvent that dries up other liquids. Make sure to spin the bottle a few times to evenly coat the entire inside of your fuel tank. Allow to dry and the acetone will evaporate along with any residue.

  Break apart, or dislodge, any rust that may be stuck in the inside of the tank by putting dry wall screws into the tank and shaking it several times. Add another pint of acetone and rinse the tank thoroughly.
- 3
  Apply duct tape to any holes or seams to keep sealer from coming out. Use putty to seal any outlet ports.
- 4
  Mix the sealer together. Most sealer will consist of two parts that need to be mixed together. Follow the manufacturer's directions for your sealer.
- 5
  Pour sealer into the tank. Use plastic wrap and a rubber band to close up the hole that you poured the sealer in. Spin the tank in your hand for a few minutes so that the sealer gets to coat the entire inside of the tank. Then pour out the sealer. The sealer will harden inside the tank, repairing the tank.
