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.

So far I only have a couple hours on the system. I have heard lots of direct positive feedback directly from guys on Facebook groups about this kit. While it is a good kit, I’m most impressed with the knowledge and customer service with Lee power steering. Makes my power steering troubles a thing of the past, and I can finally rest my concerns with their assistance.
2002 replacement of original pump after 240,000 miles.
The install went well. A couple things could be improved. I wasn’t familiar with the 90degree fittings and how difficult it was to slip hose onto them. A little WD40 makes it much easier. I didn’t want to use the 21 year old factory return hose and there wasn’t enough hose supplied with install kit. Also 90 degrees fitting there would clean things up nicely. The Saginaw up grade resulted in better steering with No pulsation.
Easy to install
Instructions were clear. I brought my bracket to a machine shop and had them mill it instead of cutting per instructions. Cut the tube that goes to the cooler for better alignment. Recommend flushing the system when done with install. Great job on designing this pump upgrade!
Highly RECOMMEND!!! My 7.3L feels like a new truck!!
I had turning issues at low speeds and stops! New factory steering pumps were put in a few times never fixed the issue!! I bought the lees power steering pump and followed the easy instructions to install it!! It was fairly Easy!! I have NO steering issues at all now!! No whinnying no turning issues even the braking is a million times better!!!! I highly recommend the Lee’s power steering pump!! Worth every penny!!
