How To Clean Tractor Diesel Tank?

How to Remove Water from Your Tractor’s Diesel Fuel Tank and Clean It Properly

Water, sedatives, or other impurities could appear in the fuel tank and clog the fuel lines if your diesel-powered Kubota tractor or construction equipment sits inactive for a few months. You’ll most likely notice this issue quickly after turning on your Kubota. If you start the engine too soon, it will most likely stop off as if it runs out of fuel.

You’ll need the following goods to complete this project:

  • The diesel fuel will be collected in a container.
  • Pump for fluid extraction using a flexible hose
  • High-pressure nozzle on an air compressor
  • Owner’s manual for your Kubota
  • Power Service Clear-Diesel Fuel & Tank Cleanser is an ultra low sulfur diesel fuel tank cleaner.
  • Fuel filter replacement (s)

Step 4: Once the tank has stopped draining, use the extraction pump to remove any fuel or sediment that has accumulated at the tank’s bottom. It may be required to use the air compressor to blow out the debris.

Step 5: Just before your fuel rail or injection pump, disconnect your fuel line. To clear any debris from the fuel lines, insert the air compressor nozzle into the hose and blow air back toward the tank. Replace and fasten the lines after blowing them out.

Step 6: Replace the diesel fuel line nut or hose on the diesel fuel tank’s base.

Step 11: Make sure your fuel system is bled. Turn the ignition on your Kubota tractor and enable the electronic fuel pump to pump fuel up to the filters. Crank the engine till it starts and self-bleeds.

A bleeder screw is located where the fuel line meets the injection pump on models with injection pumps. To purge air, open the bleeder screw and rev the engine until it starts. Close the bleeder screw once the engine has started. Please refer to your owner’s handbook to determine which system you have and for additional information.

After completing those steps, your Kubota diesel fuel tank should be clean enough to operate your tractor or other diesel-powered equipment without issue.

Is there anything I can use to clean a diesel tank?

TO CLEAN FUEL TANKS AND PREVENT PREMATURE FUEL-FILTER PLUGGING, pump or drain excess water and fuel impurities from the bottom of the fuel tank until diesel fuel shows, if possible. Fill each 20 gallon of diesel fuel with the entire contents (16 ounces) of Clear-Diesel Fuel & Tank Cleaner.

TO KEEP A CLEAN FUEL TANK AND STABILIZE FUEL FOR LONG-TERM STORAGE, DO THE FOLLOWING: Fill each 40 gallon fuel tank with the entire contents (16 ounces) of Clear-Diesel. Diesel fuel should be added to the tank.

What is the best way to clean an old diesel storage tank?

Fuel pump failures might be caused by a dirty fuel tank. Follow these step-by-step instructions for cleaning your fuel tank to avoid any difficulties.

Fuel pump failures are caused by a variety of factors. A dirty fuel tank is one of the most typical causes of failure, especially when a replacement fuel pump fails soon after installation. Contaminants and loose material, such as rust and sediment, must be removed prior to the installation of the fuel pump, as they can clog the filter, jam the turbine pump, or drastically restrict fuel flow.

Starting the fuel pump repair process with a clean fuel tank is the single most critical approach to avoid this.

You can do so by following these simple methods for cleaning your fuel tank:

  • Using an authorized container or a fuel caddy, drain all of the petrol from the tank.
  • Remove the tank (see your service manual for further instructions).
  • With a brush, clean the area where the pump is being removed.
  • Take the gasoline pump out of the tank (avoid letting residual debris fall into the tank).
  • Start a stream of clean, hot water by inserting the hose into the fuel tank.
  • Spray mild detergent in the tank while the water is filling.
  • Use a brush to dislodge debris from the tank’s sides if the aperture allows.
  • Stop the flow of water.
  • Ensure that all debris has been collected by swishing the water around.
  • Dump the polluted dirty water into a pan, making sure to catch any liquids.
  • Wipe the tank down again with a lint-free washcloth.
  • Using compressed air, totally dry the gasoline tank.
  • Inspect the tank for corrosion or physical damage, which must be repaired or replaced if found.
  • To assist absorb any residual moisture, add antifreeze/water remover to the fuel line.
  • Allow 30 minutes for the tank to dry after it has been dried.

Is it possible to put WD40 in your diesel tank?

  • Mineral Oil is made up of a mixture of alkanes and cycloalkanes.
  • Alkane Tridecane
  • Alkane Tetradecane
  • Polycyclic aromatic hydrocarbon Dimethyl Naphthalene
  • Cyclohexane is a kind of cycloalkane.

This means that WD-40 is made up of Alkanes (also known as hydrocarbons), mineral oil, and carbon dioxide.

WD-40 is flammable and combustible, with a flash point closer to that of a heavy diesel than that of gasoline.

What is the expense of cleaning a fuel tank?

The safe disposal of old gas is the first step in this procedure. The fuel tank must next be thoroughly degreased using soapy soap and hot water. Following that, use a specialist cleaner solvent to remove carbon build-ups, dirt, sticky spots, and rust.

The filth should then be washed away with water. After that, let it to dry completely. After that, replace the pipes and hoses and refill with new, clean gas.

Q: How do you know if your fuel line is clogged?

You’ll notice this if you have problems starting the automobile or if the car’s power is diminished while driving. This occurs because just a small amount of gas reaches the engine at a given time. As a result, the engine isn’t getting enough gas, which suggests that your fuel line is clogged.

Q: How long can Gas sit in a car?

Approximately 4-5 months. Following that, a chemical reaction will occur, producing hazardous compounds for the engine. It is not a good idea to store gasoline in your car. It comprises chemicals such as benzene and alkene. These elements will cause a chemical reaction that could be harmful to you.

Q: How much does it cost to flush a fuel tank?

It is dependent on the car and its complexity. However, it will cost between $400 and $1500. This is for cleaning the entire fuel system, including the injectors.

This price does not include the labor fee. If you’re having it done by someone else, you’ll need to add a little more. The price also differs from one region to the next.

Q: Can a fuel filter be cleaned?

The fuel filter is the component that keeps dirt and debris out of your fuel system. It’s made up of multiple layers of paper and nylon that are encased in a metal body. As a result, cleaning it will be ineffective. It is preferable to replace the fuel filter in order to get maximal filtration capability.

Abrasive Rust Removal

Once your gas tank is empty, you can fill it with gravel, nuts and bolts, or BBs, then fill it with liquid and shake it. Many mechanics swear by soap and water, but vinegar is a low-risk alternative that won’t harm your garage’s other surfaces.

Seal all holes with various sized plugs and materials before pouring liquid (or small gravel) into the tank. After that, start with the abrasives. After that, pour the liquid into the tank and start shaking it. You may need to construct a mechanism for shaking the tank, or you may be able to shake it manually, depending on its size.

To ensure that the abrasive materials reach every aspect, nook, and cranny, flip the tank on all sides (including upside down). After you’ve finished shaking the tank, drain the liquid and rinse it with water.

Rinsing with water helps wash out the gravel or other abrasive you’ve used, but make sure you shake the tank around to make sure it’s completely empty before letting it dry and reinstalling it on your motorcycle.

Chemical Rust Removal

Although vinegar is essentially a chemical, it isn’t as powerful as other rust-removal chemicals. As a chemical abrasive, you can use phosphoric, hydrochloric, acetone, or muriatic acid.

Filling (or nearly filling) the tank with vinegar and baking soda is the safest way of chemical rust removal. Allow the mixture to settle until it bubbles and the rust particles begin to change color. Then give it a good rinse to make sure it’s entirely empty.

Using diesel fuel to eliminate rust is another chemical alternative that is reasonably low-risk in terms of the potential for it to eat away at the interior of your gas tank. Rust can be effectively removed by using an abrasive and diesel gasoline.

Alternatively, you can clean your rusted tank with stronger chemicals in a safe dilution. In that scenario, dilute and handle the solution according to the label’s directions. Follow the time instructions carefully as well; allowing a chemical to rest for too long can eat away at your gas tank’s walls.


To utilize electrolysis for rust removal, you’ll need a sodium carbonate solution first (or soda ash). The chemical formula is Na2CO3, and the most widely accessible brand is Arm & Hammer, which may be found at grocery and other retailers. Sodium carbonate is also available in hardware stores, usually in the hot tub chemical section.

To make a solution within the gas tank, only a few tablespoons of sodium carbonate are required. Simply place the ferrous metal (iron), also known as the anode, inside the gas tank (suspended within the tank), connect the positive power source, and let the setup sit for several hours (or even days).

How often should a diesel tank be cleaned?

You want your diesel tank to be full of fuel when you clean it (so you can clean the entire tank). When you clean it, a gadget that looks like a snake descends into the tank. It vibrates and bangs against the sides and bottom of the tank to dislodge the algae growth and grime that has gathered.

The next step is to pull the fuel from the tank, filter it, and then return it to the tank.

The procedure is known as “fuel polishing,” because it removes all water and impurities (including algae growth). You will have the highest grade fuel in your tank after this procedure. From a modest 20 gallon tank to a 10,000 gallon tank, you may fuel polish tanks.

This procedure is critical because filthy fuel can harm your engine’s injectors. It has the potential to clog fuel filters and create extensive damage that would be very costly to repair in the long run.

The fuel in the tank should be examined once a year. A gasoline polishing is recommended at least once every three years.
