PSC Ford Super Duty 7.3L Steering Pump Conversion Kit
PK73FDP
The PSC Ford Super Duty 7.3L Steering Pump Conversion Kit replaces the factory Motorcraft CII pump with a Saginaw P-style hydraulic supply for heavy loads, oversized tires, and demanding off-road driving. On compatible 7.3L Power Stroke Super Duty trucks, the conversion supports the steering and Hydro-Boost brake system with a remote reservoir and dedicated cooler.
The package combines the PSC pump assembly, Hydro-Boost reservoir fittings, master hose kit, and application-specific mounting components so the hydraulic supply can be upgraded as a system. Its two return ports accommodate the Hydro-Boost return arrangement, while the separate reservoir gives the pump a dedicated fluid supply. Confirm the truck’s engine and production date before ordering; this is a specific conversion rather than a universal diesel pump replacement.

- SP1405X-6-12-7.3 pump assembly with MB03K7.3 and PP2413
- SR146 reservoir and SRK-8H-12 Hydro-Boost fitting kit
- HMK-PK73FDP master hose kit

What is included with this SKU?
The Includes section identifies the listed package contents. Where options are offered, choose the matching model year or steering system; do not assume components listed for a different SKU are supplied.
How should the hydraulic system be prepared?
Follow PSC’s installation procedure for system flushing, approved fluid, and thorough bleeding. Confirm hose connections and inspect for leaks before loading the steering system.
Why does steering fluid cooling matter on the trail?
Repeated high-load steering inputs generate heat in the hydraulic circuit. Install the supplied cooler where specified, or plan suitable cooling according to PSC’s recommendations for the complete system.
