• Flush and Replace Contaminated Fuel: If the fuel tank contains contaminated or degraded fuel, it should be drained and cleaned. Fill the tank with fresh, clean fuel and consider using a fuel additive to help prevent future issues.
  
• Test and Replace the Fuel Pump: If the fuel pump is found to be faulty, it may need to be replaced. In some cases, the pump can be repaired, but replacing it with a new or rebuilt pump ensures optimal fuel pressure and performance.
  
• Bleed the Fuel System: After any maintenance on the fuel system, it’s crucial to bleed the system to remove any air that may have entered during the repair process. Air in the fuel lines can cause starting problems and poor engine performance.
  

• Regularly Replace Fuel Filters: Set a schedule for replacing the fuel filter based on hours of operation or manufacturer recommendations.
  
• Inspect Fuel Lines and Tanks: Regularly check the fuel lines for any cracks or signs of wear, and ensure the fuel tank remains free of debris or contamination.
  
• Use High-Quality Fuel: Always use high-quality fuel and avoid storing fuel for long periods to prevent degradation. When storing fuel, use additives to prevent water absorption and degradation.
  
• Keep the Machine Clean: A clean machine, especially the fuel system, can prevent dirt and contaminants from entering the system and causing future issues.
