The SCV (Suction control valve) also known as the fuel metering valve simply controls the fuel intake volume to the HP CR pump (Not the delivery side) The SCV lives in between the high volume transfer pump and high pressure rail pump.The SCV gets constant + power from the engine management circuit.he SCV is like a solenoid that push/pulls a valve/piston on the CR fuel pump and controls the amount of pressure in the fuel rail... Think of it as a variable regulator. Most of our troubles are the dry diesel causing them to get sticky (Lack of lube).
