The Ford Powerstroke engine utilizes a unique fuel injection system called Hydraulic Electronic Unit Injection (HEUI). Absent from a normal fuel injection system are a mechanical injection pump and injection lines. The components which replace the traditional mechanical injection pump include a high pressure oil pump and reservoir, pressure regulator for the oil and passages in the cylinder head for flow of fuel to the injectors. The system depends upon high pressure oil to intensify the fuel injection pressure. The Striker Ignition Pressure Regulator increases fuel injection pressure by modifying the factory signal to increase the oil PSI throught the hydraulic amplifier circuit.
