Hey there, thanks for stopping by the forum!
These are brand-new power steering boxes designed and built by CPP, not reman or OEM units. You can use either a Saginaw “P” pump or a Type II pump, just make sure it’s producing around 1,000 PSI or more with at least 2.5 GPM of flow. We typically run a 1,200 PSI, 3 GPM pump here with great results. The adapter plate used on the F-Series kits measures 11/32" thick.
Hope that helps! If you have any other questions or need setup tips, just let us know — we’re happy to help. Have a great day and thanks again for being part of the CPP community.
