Lull 844 Fuel Tank Rust: Causes, Prevention, and Solutions

[MikePhua]

Rust in the fuel tank of a Lull 844 can cause a range of problems, from fuel contamination to poor engine performance. Rust buildup typically occurs when moisture combines with dirt and metal surfaces, leading to corrosion inside the tank. This article provides an overview of the causes, prevention, and solutions for dealing with rust in the fuel tank of the Lull 844.
1. Causes of Fuel Tank Rust
Rust inside the fuel tank is a common issue in older machines like the Lull 844. Several factors contribute to the development of rust:

• Moisture exposure: Condensation is a primary cause of rust in fuel tanks. As the temperature fluctuates, moisture can form inside the tank, especially if it's not completely full. This moisture then interacts with the metal surfaces, leading to rust formation.
  
• Contaminated fuel: If the fuel is contaminated with water or other impurities, it can accelerate the rusting process. Water in the fuel can lead to corrosion on the tank walls, while debris can clog fuel lines and filters.
  
• Lack of use: Machines that are not regularly used are more prone to rust. When the fuel tank is partially empty for extended periods, it creates a favorable environment for condensation to form inside the tank.
  
• Environmental conditions: Machines that are used in humid or wet environments are at greater risk of developing rust due to the increased moisture levels in the air.
  

2. Symptoms of Rust in the Fuel Tank
Rust in the fuel tank can lead to several noticeable symptoms:

• Poor engine performance: Rust and debris can clog fuel lines and filters, causing engine misfires, rough idling, or stalling.
  
• Frequent fuel filter clogging: If rust particles break off inside the tank, they can clog the fuel filter, requiring frequent replacements.
  
• Water contamination: Rust in the fuel tank can allow moisture to mix with the fuel, leading to water contamination. This can cause poor combustion and engine performance issues.
  
• Rust in fuel lines: Over time, rust may spread to the fuel lines, which can cause corrosion and leaks, further exacerbating the problem.
  

3. How to Inspect the Fuel Tank for Rust
To check if your Lull 844 fuel tank has rust, you can perform a visual inspection and take a few additional steps:

• Look for visible rust: Check the inside of the fuel tank for any visible signs of rust or corrosion. A flashlight can help illuminate the tank's interior if it’s difficult to see.
  
• Fuel sample: If the tank appears clean externally, you can sample the fuel. Pour a small amount of fuel from the tank into a clear container and check for signs of water or rust particles. If the fuel looks cloudy or has sediment in it, there may be rust inside the tank.
  
• Check fuel filters: Inspect the fuel filter for signs of rust buildup. If the filter is clogged or shows signs of rust, it may indicate that there is rust in the tank.
  

4. Solutions for Rust in the Fuel Tank
Once you've identified rust in the fuel tank, it's essential to address the issue promptly to prevent further damage. Here are some solutions to remove rust and prevent it from coming back:

• Clean the fuel tank: Removing rust from the tank involves cleaning it thoroughly. This process may require removing the tank from the machine. Use a fuel tank cleaning kit or a combination of a degreaser and a rust remover to clean the tank. Agitating the tank with small abrasive materials, such as nuts or bolts, can help dislodge rust particles.
  
• Fuel tank coating: After cleaning the tank, applying a protective coating can prevent future rust formation. There are fuel tank sealants available that provide a rust-resistant coating inside the tank. This coating helps protect the metal surface from moisture and corrosion.
  
• Replace the fuel tank: If the rust is extensive and the tank is damaged beyond repair, it may be more cost-effective to replace the fuel tank. Rusted tanks can lead to leaks and fuel contamination, making replacement the best long-term solution.
  
• Replace fuel lines and filters: In cases where rust has reached the fuel lines and filters, these components should be replaced to prevent further contamination.
  

5. Prevention Tips for Avoiding Fuel Tank Rust
Preventing rust from forming in the first place is the best approach to maintaining your Lull 844's fuel system. Here are some tips to help avoid future rust problems:

• Keep the tank full: Keeping the fuel tank full helps reduce the amount of air and moisture inside the tank, preventing condensation from forming. This is especially important in machines that are not used frequently.
  
• Use fuel additives: Fuel additives designed to prevent rust and water accumulation can help protect the fuel system. These additives also help keep the fuel system clean and free of impurities.
  
• Store in a dry location: If possible, store the machine in a dry environment where it’s protected from humidity and moisture. If the equipment is stored outdoors, consider using a fuel tank cover to protect it from the elements.
  
• Regular fuel system maintenance: Regularly check the fuel system for signs of contamination or rust. Clean the fuel tank, replace filters, and inspect fuel lines as part of routine maintenance to prevent rust buildup.
  

6. Conclusion
Rust in the fuel tank of a Lull 844 can cause serious performance issues and lead to costly repairs if not addressed promptly. By understanding the causes, symptoms, and solutions for fuel tank rust, you can keep your machine running smoothly and avoid expensive breakdowns. Regular maintenance, including keeping the fuel tank full, using additives, and storing the machine properly, will help prevent rust and extend the life of your equipment.
