Saginaw Power Steering Pump Upgrade Kit For Ford F-250/F-350 7.3 1999-2003 Models
The 1999-2003 Ford F-250/F-350 with the 7.3 motor is a great workhorse. Unfortunately, the power steering system can only handle street and light off road usage. When you use it as a tow vehicle and need to do extended periods of low speed steering (backing a trailer), or modify it to larger tires, the OEM pump falls short and will often fail.
Our Power Steering Pump Upgrade Kit replaces the stock Ford steering pump with our High-Performance Saginaw N-pump that has been modified with a ported housing, chromoly shaft, needle, and thrust bearings. This is the same pump that many of our off-road race teams are using to win the Baja 1000!
This kit also includes:
- CNC'd pump adaptor bracket that will bolt to the OEM bracket
- proprietary design 3.5” x 10” reservoir
- pressure hose
- return hose
- all necessary mounting hardware
Our reservoir uses a unique design to keep steering fluid perfectly still. This results in zero cavitation and reduces air in the system – which keeps operating temperatures lower, resulting in longer pump life. Our pressurized reservoir also keeps oil in and dirt out.
We do recommend adding our 6GPM in-line filter when doing the install to even better protect your system. If adding a filter, choose barbed fittings for easy installation. View Filter
If your vehicle has tires 37" or larger, we recommend using hydraulic ram assist. When adding a ram your pump will need higher flow. We offer this pump with a larger liner and billet end cap to handle the extra flow requirements for the ram. +$150
When using this pump kit, you MUST use the radiator hose that routes "through the serpentine belt". This is the more common hose, but some vehicles came equipped with the "around the belt" hose. If you need to change the hose, the Gates part # is: GAP22542.
Hydro Boost Concerns
We have come across a fair number of hydro boost issues in Ford vehicles. Once adding a higher flow pump (especially our pump set for ram assist) we often see back pressure issues that are hydro boost related.
Unfortunately these days it is hard to find a new quality hydro-boost unit. Most of what is available is remanufactured and oftentimes very low quality. Lee's has begun stocking brand new Bosch hydro boost units that we disassembled, apply our high flow porting, then re-assemble and test.

It is HIGHLY recommended to use our specialty formulated Lee Power Steering Fluid.
AC Delco or Valvoline non synthetic power steering fluid will work as a second choice but do not have the same Wear and Anti-Foaming additives our fluid has.
DO NOT USE ATF OR ANY TYPE OF SYNTHETIC FLUID.

Lee Power Steering is amazing
Great product and great customer service. Love your company and I’m happy to recommend your products and services. Highest quality products, friendly staff and ability to provide technical info so that it is easily understood made me a customer for life.
Good quality product, but installation instructions are not great.
Great service when I called on the phone. I’m running 3 trucks with the 7.3 psd. Not sure why but my wife’s truck had gone through 3 power steering pumps so I decided to give the Lee upgrade a try. So far it seems to be working perfectly. I think our power steering problems have been solved
Awesome product!! Worth every penny!
Excellent!! I’ve been chasing my tail with the stock pumps. Very well made and engineered.
Great performance, very noisy
My experience with Lee was amazing. The first pump I ordered was malfunctioning so they sent me a new one free of charge. The pump is on my 2002 F250 and is paired with my psc hydro assist and the performance is wild. It steers easier than my 2013 F350. However, my only gripe is that it makes a lot of noise inside the cab, lots of noise. With that being said, I’d still recommend this product
