Cleaning a John Deere fuel tank is a necessary task, especially if the fuel has been contaminated with water or left to sit for long periods. The process involves draining the tank, removing debris and sediment, and ensuring the fuel system is clean and functional. One common method is to use a pressure washer or garden pressure can with diesel to clean the interior of the tank, followed by rinsing and drying. Others suggest using a steam cleaner or filling the tank with diesel fuel and a strong detergent, then agitating the mixture. In some cases, it may be necessary to clean the carburetor and fuel lines as well.

What You'll Learn
Removing water from the tank
If your tractor has been sitting idle for a few months, water, sediments, or other contaminants could appear in the fuel tank and clog up the fuel lines. Here are some ways to remove water from the tank:
Using a Pressure Washer
Cover the grommet holes with duct tape and the fuel fill with Saran Wrap and a rubber band. Shake the tank and rinse it well. Dry the tank with compressed air and a long wand.
Using a Garden Pressure Can
Spray the interior of the tank with diesel to wash out the residual water. Put the plug back in, fill the tank, and purge it.
Using a Steam Cleaner
Turn the tractor upside down and use a genuine steam cleaner nozzle to clean the inside of the tank.
Using a Small Engine Vacuum
Siphon the tank and suck out the water with a shop vac. Pour a small amount of diesel into the tank to stir things up, then vacuum several times.
Using a Fuel Catching Container
Remove the fuel cap and place a fuel-catching container under the tank. Unscrew the fuel line nut or hose at the base of the tank and let the tank drain. Use an extraction pump to remove any remaining fuel and sediment.

Using a pressure washer
To clean a John Deere fuel tank using a pressure washer, first ensure the tank is almost empty. Next, remove any residual fuel by unscrewing the bung at the bottom of the tank and allowing the fuel to drain out.
Once the tank is empty, take your pressure washer and insert it inside the fuel tank. Turn on the pressure washer and spray the interior of the tank to clean it. Ensure you spray as much of the tank's interior surface as possible. The waste water and any remaining fuel will drain out of the open bung at the bottom of the tank.
After pressure washing the tank, use a garden pressure can filled with diesel to spray the interior of the tank. This will help to remove any residual water left behind by the pressure washer.
Finally, put the plug back into the bottom of the tank, fill it up with fuel, and purge the system. Your fuel tank should now be clean and ready to use.

Cleaning with diesel fuel
To clean your tractor's diesel fuel tank, you'll first need to remove the fuel cap and place a fuel-catching container under the tank. Once you've done that, follow these steps:
Step 1: Drain the Tank
Unscrew the fuel line nut or hose at the base of the fuel tank and let the fuel drain into the container. Use an extraction pump to remove any remaining fuel and sediment from the base of the tank.
Step 2: Clean the Fuel Lines
Blow out any debris in the fuel lines with an air compressor. Insert the nozzle of the air compressor into the hose and blow air back towards the tank. Then, replace and secure the fuel lines.
Step 3: Refill the Tank
Screw the diesel fuel line nut or hose back onto the base of the tank. Fill the tank with fresh diesel fuel.
Step 4: Use Diesel Fuel to Rinse
As mentioned by some tractor owners, after cleaning with hot water and detergent, you can rinse the tank a couple of times with diesel fuel. This helps to get any remaining water out of the tank.
Step 5: Add a Diesel Fuel Tank Cleaner
Finally, pour the correct amount of diesel fuel tank cleaner into the tank.
This process should leave your diesel fuel tank clean and ready for operation.

Cleaning with a steam cleaner
To clean a John Deere fuel tank with a steam cleaner, you will need to remove the fuel tank from the tractor. Place the tank upside down and use a genuine steam cleaner nozzle to clean the inside of the tank. It is important to note that real steam cleaners are rare, and this method may not be widely accessible.
For this method, you will need safety goggles, gloves, a drain pan, a steam cleaner, and clean rags. Before beginning, consult your owner's manual for any specific instructions or precautions related to your model of John Deere.
First, disconnect the battery to prevent any electrical issues. Next, locate and remove the fuel tank by detaching any parts or connections that may be holding it in place. Be cautious of any fuel spills, and avoid smoking or open flames during this process. Once the fuel tank is removed, you can begin the steam-cleaning process.
Place the fuel tank upside down on a stable surface and securely attach the steam cleaner nozzle to the tank opening. Ensure that the steam cleaner is specifically designed for fuel tank cleaning and follow the manufacturer's instructions for safe and proper use.
Activate the steam cleaner and allow the steam to penetrate and clean the interior of the fuel tank. The steam will help loosen and remove any built-up dirt, debris, or contaminants. After steam cleaning, it is important to rinse and dry the tank thoroughly before reinstalling it.

Cleaning the carburetor
To clean the carburetor of your John Deere lawnmower, you must first park the mower on a hard floor that can be cleaned in case of any fuel spills. Once the mower has cooled down, check the outside of the mower and ensure it is free of debris.
Next, remove the spark plug cable and air filter from the engine. If the air filter is dirty or clogged, clean or replace it, as a dirty air filter can cause the engine to produce black smoke and increase fuel consumption. Before proceeding, ensure that the fuel valve is closed to prevent any fuel spills. If your mower does not have a fuel valve or it is not functioning, you must empty the gas tank.
Now, you can start to detach the carburetor's fuel line. Some fuel may spill, so be prepared. You may also need to remove the throttle and choke cable. Next, remove the hardware attaching the carburetor to the air filter housing. Slowly remove the springs, being careful not to stretch them out. You may need to twist the carburetor to get the springs off.
Take photos of the carburetor as you disassemble it to make it easier to reassemble. Once the carburetor is removed, clean all parts with carburetor cleaner and blow out any small holes or passageways with compressed air. Remove all non-metallic parts, as the carburetor cleaner will cause them to disfigure and decompose. Wash the carburetor cleaner off the metal parts with warm, soapy water, then rinse with clean water. Dry the metal parts with compressed air.
Finally, reassemble the carburetor with new seals. If the problem persists, you may need to replace the carburetor or consult a professional.
