Accessing the IPR valve on a Ford 6.0L or Navistar DT466 shouldn't mean sacrificing the electrical connector. The 303-1112 specialized socket is the only way to perform damage-free HEUI service.

The Challenge of the IPR Valve

The Injector Pressure Regulator (IPR) valve is the brain of the HEUI system, but it is tucked away in a recessed nightmare on the High-Pressure Oil Pump (HPOP). Standard deep sockets won't fit the narrow clearance, and they certainly don't account for the sensitive plastic electrical connector. The 303-1112 (ZTSE4666) socket features a precision-cut relief slot, allowing you to slide over the valve and apply torque to the hex without touching the connector.

• Slotted Connector Clearance – Specially machined to clear the plastic plug, preventing expensive sensor damage.
• Deep, Narrow Profile – Engineered to reach into the tight recesses of the HPOP housing where standard tools fail.
• High-Torque Engagement – Grips the hex firmly to break loose heat-seized valves without rounding.
• Wide Application Range – A single tool for Ford 6.0L Powerstroke, Navistar DT466, DT570, and MaxxForce engines.
• Professional Shop Grade — Heavy-duty steel construction designed for the daily heat and oil of diesel service.

Precision Tooling for High-Pressure Oil Systems

The 303-1112 IPR Socket is an investment in efficiency. By avoiding broken sensors and rounded valves, you keep your repairs profitable and your customers on the road.
