Motorcraft HPP1RM High Pressure Oil Pump 7.3L Powerstroke Diesel Remanufactured

The Motorcraft HPP1RM is a remanufactured high-pressure oil pump (HPOP) designed for Ford 7.3L Powerstroke and T444E diesel engines. This critical component is essential for the HEUI (Hydraulic Electronic Unit Injection) fuel system, pressurizing engine oil to 2,500-3,000 PSI to actuate the fuel injectors. Without adequate oil pressure from the HPOP, injectors cannot deliver fuel effectively, resulting in poor performance, difficult starting, and reduced power output.

Key Features:

• Remanufactured to Original Equipment standards with latest design improvements
• Undergoes stringent testing for leaks, flow performance, vibration, and corrosion resistance
• Tested to Ford's durability standards equivalent to 10 years/150,000 miles
• Direct replacement for worn or failed factory pump
• Restores proper injection control pressure for optimal fuel atomization
• Eliminates common symptoms like rough idle, poor fuel economy, and P1211 check engine light

This pump is specifically designed for 1999.5-2003 Ford F-Series and E-Series vehicles with 7.3L Powerstroke engines, as well as compatible Navistar engines with serial numbers 843990 and higher. The remanufactured unit meets all OEM specifications and is backed by Motorcraft's warranty coverage. Replacing a failing HPOP restores engine performance, improves fuel efficiency, and ensures reliable injector operation for both daily driving and heavy-duty applications.
