Step-By-Step Guide To Clean A Vehicle’s Fuel Tank

One significant cause of fuel pump and fuel filter failure is the problem with a gas tank. Thinking about it, thousands of gallons of gas go through a gas tank yearly. It’s inevitable for the debris and sediments to end up in the gas tank, resulting in a rusted tank. All this can be avoided by cleaning the vehicle’s fuel tank via gas tank cleaner. Regular fuel tank cleaning will prevent engine problems and keep the fuel pump functioning for a long. This article will guide people through simple steps a vehicle owner can follow in cleaning a fuel tank.

  1. Safety First 

Working with fuel systems can be dangerous due to their explosive nature. Here listed are some safety tips that should be followed before commencing the gas tank cleaning process:

  • Work is a clean and organized area.
  • Place a fire extinguisher by the side.
  • Wear a face mask to minimize the inhalation of fuel fumes.
  1. Drain the Fuel Tank

Before removing the gas tank, ensure that its empty of fuel. It’s a necessary safety precaution, and taking some weight off will make the process easier. Some fuel tanks feature a drain cock to drain the fuel neatly. If not, use a gas line to remove the gas.

  1. Remove the Fuel Tank

When removing the fuel tank, leave all valves and caps in their respective positions to make reinstallation easier. After taking it out, inspect the tank for sediment, rust, or holes.

  1. Wash the Fuel Tank 

To wash the fuel tank, use effective gas tank cleaner and disperse it over the inside surface of the gas tank by swirling or shaking it. Depending on the buildup inside the tank, it might take a few soaking sessions to clean the bottom thoroughly. Suppose an individual is trying to clean a motorcycle fuel tank and haven’t been able to remove the same. In that case, he can still clean it effectively using a combination of different fuel tank cleaners.

  1. Clean the Fuel System

For a more effective tank-cleaning process, make sure to run detergent-based fuel additives through the vehicle’s fuel system- fuel lines, intake valves, carburetor, and combustion chambers.

  1. Replace the Fuel Filter

Now that an individual is going through the effort of cleaning the gas tank and lines, he should also replace the fuel filter. An old filter can restrict the flow of the entire fuel system. It further makes the fuel pump work harder and wears out faster.

  1. Put the Fuel Tank Back

When putting the fuel tank back after cleaning it, ensure all caps, hoses, and values are securely fitted and tightened. The slightest gas leak can leave the potential risk for environmental or fire.


Cleaning the fuel tank properly using an effective gas tank cleaner ensures the dust, debris, grime, and harmful sediment don’t get into the vehicle’s engine and damage it. Regular maintenance is crucial to prevent fuel lines from clogging up and keep the fuel pump running efficiently for a long. So, if the vehicle or its engine has been sitting for a long or it’s functioning roughly, it may be time to clean the gas tank.
