This is the Bosch HP005X, a high-pressure oil pump (HPOP) remanufactured by Bosch, the original equipment maker of this pump. It is the second of the four Bosch pump numbers for the 7.3L: it covers the 1996 to 1997 Ford 7.3L Power Stroke in F-Series trucks and E-Series vans, and the International T444E from engine serial number 216,544 through 661,894. It replaces Ford F6TZ-9A543-ARM and F6TZ-9VA543-ARM and Navistar 1825248C91, 1825259C91 and 2503703C91. The mounting gasket is included. The injection pressure regulator (IPR) valve is not.

The HPOP supplies the high-pressure engine oil that fires the HEUI injectors. A worn pump shows up as a long crank, an engine that will not restart hot but starts again once the oil cools, or low power with low injection control pressure. A leaking IPR valve, leaking injector O-rings or hoses and a low oil reservoir cause the same complaints, so rule those out first. Unlike the first 1994 to 1995 pump, this one has no drain check valve and carries the edge filter inside the pump, not in the IPR valve.

Specifications

Fits / Applications

• Ford 7.3L Power Stroke, 1996 to 1997, F-Series and E-Series
• International T444E, engine serial numbers 216,544 to 661,894
• Ford engines from serial 187,100 to 216,543 (from the mid-1995 change, often called 1995.5): catalogs disagree between this pump and the HP004X. Confirm by serial number.
• Other engines take other pumps: HP004X for the first engines, HP007X for serial 661,895 to 843,989, HP008X from 843,990

The IPR valve is not included. Move yours to the new pump with a new seal kit, or fit a new one. This pump carries its own edge filter, so it pairs with the later IPR valve, not the early one with the filter built in. Use the mounting gasket supplied. HEUI injectors run on engine oil, so change the oil and filter, fill the high-pressure oil reservoir and prime the system before the first start.

Frequently Asked Questions

Will the HP005X fit my 1997 Ford F-250 or F-350 with the 7.3L Power Stroke?

Yes. HP005X is the pump for the 1996 to 1997 7.3L Power Stroke, engine serial numbers 216,544 to 661,894. If you are not sure of the build, call 530-668-0818 with the engine serial number.

What numbers does the Bosch HP005X replace?

Ford F6TZ-9A543-ARM and F6TZ-9VA543-ARM (also written without hyphens, F6TZ9A543ARM), and Navistar 1825248C91, 1825259C91 and 2503703C91. Catalogs also cross it to Rexroth R98620005R and Alliant Power AP63622.

How is the HP005X different from the 1994 to 1995 pump, HP004X?

The HP004X has a drain check valve and relies on an edge filter in the IPR valve. The HP005X has no drain check valve and carries the edge filter inside the pump. Catalogs split the two by engine serial number, so check yours before ordering.

Is it new or remanufactured, and does it come with the IPR valve?

It is remanufactured by Bosch, the original equipment maker of this pump, and a refundable core charge applies. The mounting gasket is included. The IPR valve is not.
