Warm weather can contribute to water issues in the engine.

This article will cover everything you need to know about removing and cleaning your tractor’s diesel fuel tank.

When the weather gets warmer, there’s an increase in diesel fuel tank water issues.

Water, sediment, and other pollutants might get into your diesel-powered fuel tank and clog the fuel lines if it sits unused for too long.

If water or debris clogs fuel lines, the engine will instantly shut off after you switch it on.

Another issue is a diesel fuel leak. When this happens, you have to empty the tank and clean the pipes.

Tools to Clean Your Tank

You’ll need the following items to begin:

  • A wrench set
  • Diesel fuel storage tank
  • A pump that has a bendy hose for extracting fluids
  • Nozzle for a high-pressure air compressor
  • Your tractor’s Owner’s Manual
  • Cleaner for Ultra Low Sulfur Diesel fuel tanks, such as Power Service Clear-Diesel Fuel & Tank Cleaner
  • A new fuel filter


  1. Remove the gasoline cap.
  2. The fuel catch can is usually placed behind the tank.
  3. To disconnect the fuel line at the tank’s base, unscrew the hose or nut, and drain the tank.
  4. After the fuel has drained, use an extraction pump to remove any sediment that has settled at the bottom of the tank. You may need to use an air compressor to remove any remaining debris.
  5. To clear out any debris in the fuel lines, insert the nozzle of an air compressor into the hose and then direct the airstream back towards the tank. Keep in mind that after blowing out the lines, they must be replaced.
  6. Reconnect the diesel fuel line to the tank’s undercarriage.
  7. If the vehicle is equipped, drain the water separator and replace gasoline filters.
  8. Fill the tank with clean diesel fuel.
  9. Put the fuel lid back on and turn the tractor on.
  10. You must first bleed the fuel system to prime the fuel filters on newer tractors. Turn the key until the engine self-bleeds and starts.

A bleeder screw is located at the fuel line junction and pumps on injection pump engines.

Turn the engine’s crankshaft to release any trapped air while opening the bleeder screw.

DON’T FORGET to refer to your owner’s handbook if you’re unsure which system your tractor has or would like more information.

Before starting the engine, always check that the bleeder screw is tightened.

Using a diesel-powered machine, cleaning your fuel tank regularly is essential. This will keep your tractor working as it should.

Make sure to refer to your owner’s manual when cleaning your specific diesel engine.

Diesel engines often have fuel tank problems, resulting in decreased performance, increased fuel consumption, or engine failure. A dirty diesel tank can be cleaned using various tools and materials.

Here are 4 of the easiest methods:

1. Pressure Washer

A strong water spray may be used to clean the inside of a diesel tank of dirt and impurities. Use eye protection and protective clothing, such as gloves, long sleeves, pants, and close-toed shoes.

2. Drain Cleaner

Pour some drain cleaner into the top of the tank’s opening. Use the cleaner as instructed.

Allow the tank to rest for a while after adding the cleaning solution for it to flow through the system.

3. Baking Soda

To clean your tank with baking soda, mix one cup of baking soda into a gallon of water.

Allow the solution to sit for 10 minutes before draining it away. Rinse the area with clean water to remove any residue that remains.

4. Vinegar

Heat two cups of water and add them to a bucket with white vinegar.

Stir the mixture well for 5 minutes before dumping it into your tank. Rinse off the inside of your tank by adding more clean water and repeating this process.

You can also use baking soda and add vinegar to create a cleaning chemical reaction.

Rust and corrosion can wreak havoc on farm equipment. If it isn’t prevented or managed, it can ruin your tractor entirely.

Corrosion and rust are still problems for many metal components in the agricultural sector, despite improvements in materials and engineering.

Rust and corrosion can wreak havoc on farm equipment, necessitating costly repairs or replacements.

Fortunately, there are several things that farmers can do to prevent rust and corrosion inside their diesel fuel tanks.

One of the most important things farmers can do is ensure that their tanks are properly cleaned regularly.

This will remove any dirt, debris, or water build-up that could cause corrosion.

Another helpful tip is to add a rust inhibitor to the fuel tank. This will create a protective barrier between the metal and any corrosive elements.
