Dirt or other debris in your fuel tank can cause performance issues with your vehicle. Luckily, there is a way to clean your fuel tank without having to remove the tank altogether. Just follow these steps:
  • Disconnect all the fuel lines
  • Fully drain the fuel tank into a designated gas can
  • Degrease the fuel tank by adding a special degreaser (or regular dish soap and hot water will work). Let this sit for 24 hours
  • Use a pressure washer to rinse out the tank
  • Apply a chemical cleaning solution to the tank and let sit for several hours
  • Pressure wash the tank again to remove any remaining rust or dirt
  • Let your gas tank dry completely – usually 24 to 48 hours – before adding fuel
Frequently replacing your fuel filter can keep dirt and debris out of your gas tank and keep your vehicle running smoothly. You can also perform regular maintenance on your car insurance policy to ensure you’re still getting the best deals.
