Cleaning Process

• Draining Remaining Fuel
  Use a siphon pump to transfer all remaining fuel from the tank into a designated container. Ensure you work in a well-ventilated area to prevent the buildup of flammable vapors.
• Removing Detachable Components
  After draining, remove any detachable parts such as the fuel sender unit or filler neck to gain better access to the interior of the tank.
• Inspecting for Contamination
  Thoroughly inspect the tank interior for signs of contamination, including sludge, rust, or debris. Assess the level of buildup to determine the appropriate cleaning approach.
• Cleaning the Interior

  For light contamination: Wipe the inner surfaces with a rag soaked in a suitable cleaning agent.

  For heavier buildup: Use a stiff-bristled brush to scrub the walls, bottom, and corners of the tank thoroughly, ensuring all deposits are loosened.

  Important: Choose a cleaning agent compatible with steel that won't leave harmful residues.

• Rinsing the Tank
  Thoroughly rinse the tank with a clean solvent or distilled water to remove any remaining cleaning agent and dislodged debris. Repeat the rinsing process several times until the runoff is clear and free of contaminants.
• Drying Process
  Allow the tank to dry completely before reassembly. This can be done by leaving the tank in a well-ventilated area for an extended period or using a low-pressure air blower to circulate air inside. Ensure no moisture remains to prevent rust formation and fuel contamination.
• Reassembly & Refilling
  Reattach all detachable components and refill the tank with clean diesel fuel. Replace the fuel filter to ensure any remaining debris or contaminants are not circulated into the engine.
