1999.5-2003 Ford 7.3L Power Stroke & T444E High-Pressure Oil Pump (HPOP) | Bosch HP008X Remanufactured
This is the Bosch HP008X, a high-pressure oil pump (HPOP) remanufactured by Bosch, the original equipment maker of this pump. It is the 17 degree pump for the 1999.5 to 2003 Ford 7.3L Power Stroke in F-Series Super Duty trucks, the Excursion and E-Series vans, and for the International T444E from engine serial number 843,990 on. It replaces Ford F81Z-9A543-CRM and Navistar 1831449C91 and 2589446C91. 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. Late 1999 engines went to larger injectors, and the pump went from a 15 degree to a 17 degree swash plate to feed them. The pumps for earlier engines are different part numbers.
Confirm Fitment Before You Order
The 1999 model year is split. Early 1999 Super Duty trucks, generally built up to about December 7, 1998, take the HP007X, and later 1999 trucks, often called 1999.5, take this HP008X. By Navistar T444E serial number the catalogs put the break at 843,990: serial 661,895 to 843,989 is the HP007X. If yours is a 1999, send us the build date, the engine serial number or the number on your old pump. Call 530-668-0818 and we will confirm the exact match at no charge before anything ships.

Fits / Applications
- Ford 7.3L Power Stroke, 1999.5 to 2003: F-Series Super Duty, Excursion and E-Series
- International T444E, engine serial number 843,990 and up
- Not for early 1999 trucks (generally built up to about December 7, 1998) or T444E serial 661,895 to 843,989: those take the HP007X
- Not for 1994 to 1997 engines: those take the HP004X or HP005X
The IPR valve is not included. Move yours to the new pump with new O-rings, or fit a new one. These engines use quick-connect high-pressure hose fittings that seal on an O-ring, so check them for leaks while you are there. 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 HP008X fit my 1999 Ford Super Duty?
Only if it is a later 1999 build, often called a 1999.5. Early 1999 trucks, generally built up to about December 7, 1998, take the HP007X, and the catalogs put the engine serial number break at 843,990. Call 530-668-0818 with the build date or engine serial number and we will confirm.
What numbers does the Bosch HP008X replace?
Ford F81Z-9A543-CRM (also written F81Z9A543CRM) and Navistar 1831449C91 and 2589446C91. Catalogs also cross it to Rexroth R98620008R, Delphi HTP108 and Alliant Power AP63624.
Is the HP008X the 15 degree or the 17 degree pump?
It is the 17 degree pump used from late 1999 through 2003. The 1994 to early 1999 engines were built with a 15 degree pump, and their replacement pumps are different part numbers.
