Fuel Distributor

The fuel distributor mechanically controls fuel to the injectors. Air being drawn over the sensor plate raises or lowers the fuel distributor control plunger. Differential pressure is the difference between upper (injector supply) and lower (fuel return) chambers of the fuel distributor, controlled by the differential pressure regulator. This controls the pressure differential at the fuel distributor metering ports, which determines the fuel flow to the injectors and air/fuel mixture.
