The AirDog® Fuel Preporator®, with the capability to provide fuel at flows and pressures beyond the maximum requirements of the   engine, receives fuel under vacuum from the fuel tank containing entrained air/vapor, particulate contaminates and unknown quantities of   moisture. The fuel passes through the water separator which removes the water and large particulate contaminates that could damage or   jam the gearator fuel pump. The fuel, with only entrained air/vapor and tiny particulate
  contaminates remaining, enters the fuel pump.

  The fuel, now under positive pressure flow, enters the filter. As the fuel passes through the filter media and the remaining particulate   contaminates are caught and contained, the entrained air/vapor is also separated. Through the POSITIVE FUEL AIR SEPARATION   FEATURES of the PATENTED FUEL PREPORATOR® the separated air/vapor is discharged from the filter through the Primary   Air/Vapor Discharge Port and into the return to tank passage after the regulator. The fuel passing through the filter media {free of   contaminates & power robbing air/vapor and at pressures and flows to meet the needs of the engine} exits the fuel filter through two   passageways. The fuel for the engine, passes into the fuel pickup tube
  and out to the engine.

  The excess fuel not needed by the engine is released through the pressure regulator to combine with the air/vapor
  and foam as it returns to the fuel tank. The regulator controls the fuel pressure to the engine.

  Small & Compact: ONLY 7”L X 10”T X 3.2”W

  Dual Feed Gerotor Pump: Quiet, Efficient, Long Lasting!

  SINGLE PIECE PUMP BODY: Replaces the old 3 piece pump design reducing
  the number of parts, unit size, and weight. This results in a sleek, low profile
  pump assembly and eliminates the need for leaky, messy gaskets!

  “VACU” SEAL TECHNOLOGY: All PureFlow® pump system shaft seals operate
  under vacuum instead of pressure for extra long seal life.

  Mounts to frame - NO Drilling required!
