Jag Power Steering
I have been looking for the year or model number for the GM Saginaw Power
Steering pump. Does any one have some info that could help? And also has anyone rebuilt their Rack? Just about ready to crank up the motor and would
like to have all in place. The Jag front end I used I believe was 1979.
Thanks
George

Power steering pump
George
I used the Jaguar p/s pump that I took out of the 79 Jag XJ12 that my IFS came out of. I am running a Chev 350 so I used some of the Jag p/s pump mounting hardware and made a bracket to fit the Chevy motor. You should be able to do this with any motor.
I bought a remanufactured rack and pinion unit from Rock Auto (a little expensive but worth it).
For hoses I used high pressure hose with screw on A/N fittings and fittings that adapted the rack and pinion to the A/N fittings. That way I was able to custom make the hoses to fit as needed. Works well in my 51 F1.
Here are photos.
Hope this helps.

What engine are you using?
I used a 89 E250 as a donor engine 302 and pump (this pump is a Saginaw)I used the hoses from the van. My steering is good but my rack is lose i used the old mounting bushings

I confess that I do not remember exactly the difference in pressures from the Saginaw design and the Ford design but I think that the Ford pump pressures run lower I know there was a reason that I went Saginaw. The Jag used a Saginaw pump.
EDIT:
See below from a 2001 Street Rodder Magazine article:
But if you ran that Mustang II with a stock GM power steering pump
you could give it credit for introducing a touchy, light steering wheel. For
whatever reasons, in the early ’70s Ford designed their new power steering
racks to operate in the 700- to 800-psi range, and it worked just fine with
Ford pumps—after all, they were designed for it. The problem was that a
whole bunch of rods ran GM engines. Actually, engines weren’t the problem.
The real problem was that GM engines ran GM pumps—and for whatever
reasons, GM designed the pumps for 600- and 800-series steering boxes to
operate in the 1,000- to 1,200-psi range. So as you can imagine, things got a
little spooky—especially at speed. Some of
these idyllic swaps and
conversions
that looked so good on paper often flopped once on the pavement
What I can tell you is that the Saginaw Pump with my Jag IFS is just right, power steering with imho the right amount of feel. As an example, many years ago I drove a friends 56 F100 with the old and then popular Chrysler torsion bar setup. Road feel was non existant.

Dan thanks for all the info very helpful!! Great pics looks like you are doing
a great job on your truck. I haven't done any of the AN fittings don't you need
a special tool koul to join fitting and line? Needless to say thanks a lot for answering my question. That is what is great about this site.

I'm going to need this info as well. I have a 5.0 from a '97 Explorer. It has a ps pump with a remote reservoir. I have no idea if it will work with the JAG ifs. It's going to be a crap shoot. Unless someone know what pressure it runs. It's not exactly easy to find that info out here in the WWW.

Power steering pump
The special tool for the A/N fittings is shown in the photo. It's the two silver bars. They go around the A/N fitting and clamp in a vise to hold the fitting when you slip on the hose. A little oil in the end of the hose and it slips easily onto the fitting. The tool was $19 and well worth it.
What you see in the photo was around $350. A little expensive but made it easy to create custom hoses. I am sure a hydraulic shop can make hoses for you cheaper.
Take care

George one thing I would advise is too take in as big a picture as you can on the choice of engine and pump because you may want AC you may want a rear oil sump or a serpentine belt system with fuel injection and all that needs to fit around the rack, fire wall, and under the cab floor
Good luck
