This G4 Diesel Fuel Stop Solenoid valve, immediately and safely, shuts down engines by reversing fuel flow and creating a vacuum in the injection pump. 

• This 2/4 Way Solenoid Valve will very reliably stop a diesel engine in any situation.
• Because, contrary to normal stop solenoids, which act on the pump stop lever and
  become ineffective whenever the fuel rack sticks, this valve acts directly on the fuel
  supply to the pump.
• In stop position the suction side of a fuel supply pump and its output side are
  reversed, which then creates an instant vacuum in the fuel injection pump galley, the
  engine speed immediately drops to zero.
• The same valve can be used in “energized to run” or “energized to stop” mode
  simply by reversing the connecting hoses.
• The installation of the G4 valve is quite simple. Attached description illustrates the
  connecting method for both modes, which are also marked on the valve itself.
