BLACKHORSE-RACING HPOP High-Pressure Oil Pump Seal & Base Gasket Kit for Ford 7.3L (1994–2003) — Complete Seal Set

Complete HPOP high-pressure oil pump seal and base gasket kit engineered to restore leak-free operation on Ford 7.3L engines (1994–2003).

This BLACKHORSE-RACING HPOP kit supplies the seals, O-rings, and base gasket required to service the high-pressure oil pump and regulator on 7.3L Power Stroke engines. The set replaces common OE part numbers (F6TZ-9417-AA, 2C3Z-9G804-AB, 4C3Z-9C977-AA) and includes extra components often omitted from aftermarket kits so you can complete a thorough rebuild without sourcing additional parts.

What parts are included and why do they matter?

The kit contains all seals and O-rings needed to disassemble and correctly reassemble the HPOP and its mounting interface, plus a precision-cut base gasket to stop leaks where the pump meets the engine block.

• Full complement of regulator seals and O-rings for internal leak prevention
• High-quality base gasket to replace the pump-to-block seal
• Additional small seals and retainers typically missing from other kits
• Materials selected for oil resistance and long-term dimensional stability

How does this kit improve pump reliability on a 7.3L Power Stroke?

Replacing aged seals and the base gasket restores correct oil pressure and prevents external leaks that can lead to performance issues. New elastomers and a properly fitting gasket help maintain regulator seating and reduce the risk of fast wear from oil leakage or contamination.

• Stops external oil seepage at the pump mounting surface
• Restores regulator sealing to preserve correct high-pressure oil delivery
• Helps prevent premature component wear due to oil loss or ingress of dirt

Is this kit compatible with my truck and which OE numbers does it replace?

This BLACKHORSE-RACING kit is manufactured to fit Ford 7.3L Power Stroke diesel engines built between 1994 and 2003. It is designed to replace the listed OEM numbers so you can match it to service diagrams and parts lists.

• Includes extra seals found on factory repair diagrams

What should I expect during installation and routine maintenance?

Installation requires basic mechanical skills and access to standard hand tools and a clean work area. Replace all seals in the kit, torque fasteners to manufacturer specs, and inspect mating surfaces for damage before reassembly to ensure a leak-free result.

• Clean mating surfaces thoroughly before fitting new gasket
• Lubricate O-rings with engine oil for easier seating and correct sealing
• Follow torque values from repair manual to avoid distortion or leaks
• Inspect pump and regulator components for wear while disassembled
