Cummins P/S guide

This page is intended to prove help with plumbing when doing a cummins swap .. it will be added to and updated as I acquire info ..

Most *dodge* Cummins engines come with a saginaw power steering pump . The high pressure fitting is usually M16 1.5 bump tube o-ring fitting, I like to Adapt to -6 AN / JIC .. or a good fitting would be a STEEL Keyser Manufacturing 100 4343 https://www.summitracing.com/parts/KYS-100-4343

or a aluminum Russell AN Fitting 648060……..

The Ford power steering box is usually a 1/2-20 bump tube o-ring fitting

I have been trying to find a steel fitting but so far only have found an aluminum Russell Performance 648010 https://www.summitracing.com/parts/rus-648010

The ford Hydroboost brake booster has 3 connections , low pressure return is just a barb fitting with hose clamp … One fitting is 18 1.5MM bump tube o-ring steel to -6 is( Keyser Manufacturing 100 4344) the other is a 16mm 1.5 bump tube o-ring . The other fitting is the same 16mm 1.5 as the dodge p/s pump .

The AN-6 or 3/8 JIC hoses can then be made to length with straight / 45/ 90deg fitting as any hydraulic shop or ordered from https://www.discounthydraulichose.com

Return low pressure from pump or from hydroboost should return to the pump and they can be T’d if the pump only has one return fitting , rubber hose and hose-clamps is fine .

Ford a swap in a 1980-97 Ford truck you should only need the one hose from the pump to steering box .. for a 99+ Ford truck you should only need one new hose from the pump to hydroboost ,Here are some pics of a setup on a 1999 F250 .
