Re: George...

Newer power steering pumps have higher flowing systems due to different valving inside the pump. This is good for modern steering systems designed for higher flow rates and it keeps the fluid from getting as hot, but the 69's steering system cant handle that capacity and it makes the steering feel too light and twitchy. Luckily there is a cheap fix so that you can use the factory pump on the 5.3, keep good steering feel with an older steering box, and allow you to use the old pressure line on your vehicle with out any fancy adapters or custom lines.

I don't know when the General changed, but some time in the 80's I think is when they started using an o-ring fitting on the pump end of the pressure hose and older pumps used a double flare system. I also don't know if all o-ring pumps are high volume/pressure, but I doubt it... But, stay with me here because, I do know that the double flare fittings are all lower volume/pressure. Told you there wold be a payoff for continuing.

I sold the previous engine with all of the accessories on it, so I didnt have my old pup to part out, but I did go to the junk yard and pull this baby out of a pile of junk. It has the double flare fitting I was looking for.
