Review on Enhanced OTC 6764 Injector Pressure Regulator Controller for Ford 6.0L Diesel Engine - Optimize Performance and Fuel Efficiency by Dave Hunt

Does what it says on the tin. Actuates the IPR valve to pressurize the HPOP system in Ford 6.0 vehicles. You can also check the removed intellectual property rights. You will not receive any indication of the triggering. You will need to blow into the end of the IPR or use an air hose. IPR is normally open. When triggered, the valve closes. The clips are kind of stupid. It's best to just cut them off. This makes removing the connector easier, especially if you snap the IPR into place.
