Ford 7.3L Power Stroke HPOP | 1994-1995 | HP004X | Bosch | Remanufactured

Remanufactured Bosch high pressure oil pump (HPOP) for 1994–1995 Ford 7.3L Power Stroke and Navistar T444E engines, part number HP004X. Ford references it as F4TZ-9A543-BRM. Supplied with a mounting gasket. The HPOP supplies regulated high-pressure oil to the HEUI injectors, which cannot fire without it. This pump fits 1994–1995 engines only — later 7.3L engines use different pumps.

Fitment gate — this pump is for 1994–1995 engines only. The 7.3L used several different HPOPs across its production run, and 1996 and later engines take a different pump. Confirm your engine serial number falls within 5,500 to 216,543 before ordering, since 1994 model year trucks span the start of production.

Second fitment gate — early 7.3L pumps up to 1999 use a 15-degree swash plate; 1999 and later pumps use a 17-degree plate with a higher flow rate. They are not interchangeable.

Installation note — make sure the drive gear is fully seated on the pump before fitting the bolt and washer. If the gear is not seated correctly it can bind or slip, producing a no-oil-flow condition and an engine that will not start.

Core return — this is a remanufactured exchange unit and a core return applies. Cores must be serviceable to receive full credit.

Conclusion

This is a remanufactured Bosch high pressure oil pump for 1994–1995 Ford 7.3L Power Stroke and Navistar T444E engines, replacing Ford F4TZ-9A543-BRM and supplied with a mounting gasket. Confirm your engine serial number falls within range before ordering, since the 7.3L used several different HPOPs and they do not interchange.
