Power Steering Pressure Hose
What's the difference between the 73 - 79 power steering box & pumps and the 80 - 91 power steering box & pumps? What I've got is a 1973 Suburban that in the next week or two I'll be installing a 1991 engine with the serpentine belt accessories on it with the 1991 power steering pump. I'm assuming the 73 - 79 power steering box & pumps are SAE standard threaded and the 80 - 91 power steering box & pumps are metric threaded. If this is so is there a power steering pressure hose made for this kinda swap? If not I guess I'll have to have a local hydraulic supply shop make me one.

Re: Power Steering Pressure Hose
Primer, I would check direction of rotation on both P\S pumps. If they are the same just swap the pullys from one pump to the other. Option 2 would be to take the 1" hose connection out of each pump and see if they will screw into the other pump. Be REAL careful not to let the pressure regulator valve and spring pop out. Either way you can maintain stock hoses without haveing to make something special, which would be a problem if it broke 100 miles from home. jim

Re: Power Steering Pressure Hose
One of my buddies did mention trying to swap the pumps, they both turn clockwise. The pumps do look like they bolt up in the same places, I'd have to pull the pulleys off to see if the shafts on the pumps are the same length & diameter. I did not think of trying to just change the fitting on the back of the pump, this might be a better idea because my old pump is leaking & would nee to be resealed, the newer pump is not leaking.
