Power streeing pump for Mustang II

richard 36dodge · April 22, 2006, 08:27:34 AM

I want to use an old style rebuilt small block Chevy '68 type power steering pump with reservoir. I have the '68 brackets and the crank pulley for the short water pump. Will this pump work well with a '79 up Mustang rack ? Do I have to cut the pressure spring to lower the pressure of the pump to work properly ?
I have all the info about the hoses.
Thanks for all your help !

Yes it will work. No you don't have to mosify the pressure.

Nope! Don' touch a thing. I put an older Chevelle pump on my '34 which has an '89 Mustang rack. It works fine. The only hitch is the fittings. I had to buy both Ford and Chevy hoses and swap the ends. There is a company on the net called "Gotta Show" or something like that that sells the hoses already made up. Good Luck!

One question on the hoses, Do they come out at a 90 degree angle ?
There is not a lot of room between the bottom of the pump and the part of the rack that has the fittings holes.
I will use the Chevy pump.
THANKS FOR THE INFO !!!

The high pressure side of the pump attaches to a hose with a 90 on it. The low side is a ~3/8" pipe with a 90 on it. I put a hose over that one and used a tubing clamp over it. Both of the fittings were on 90's on the rack side. My rack is about 8 inches away too. Does that answer your questions?

I have a '75 or '76 power rack that is good. Can I use it with a GM pump ?
I have been told that I can lower the pressure of the pump by cutting about 1/3 off the pressure spring. It has about 3 1/3 turns form lock to lock with flair fittings. If not I will get a rack from a '79 up MUstang.
Thanks for all the info.

I was told to lower the pressure too. But others said it wasn't necessary. I used it as is and it works fine. Good luck!

I drove my truck with the gm ps and there was too little feel to the steering on the 84 t-bird rack. I bought a Borgesson kit to reduce the pressure for about $16.00 and set the pressure lower and the steering feel was better. Ed ke6bnl. I got the fittings made up at napa I have a very short distance to hook up the lines and they fitted them with all the fittings to make it work. Ed ke6bnl
