  1. How the AMSOIL Dahl System Works
  2. Contaminated fuel enters the inlet port.
  3. The fuel is directed down through the centertube.
  4. Fuel flows through the reverse flow valve
  5. As fuel is discharged from the depressurizer cone, 80 percent of the contaminants are separated from the fuel. Fuel rises upward and most of the solid contaminants and water settle into the bowl's quiet zone.
  6. As the fuel rises upward, any remaining small water droplets collect on cone, baffle and bowl surfaces. The size and weight of the droplets gradually increase causing the droplets to flow downward into the sump.
  7. Fuel is then filtered completely by the filter element. The clean fuel then continues up through the outlet port to the pump and injection system.
