Saginaw pump issues, PLEASE HELP!
I'm really at a loss to what the h#ll is going on. Two Saginaw power steering pumps have taken a crap on me. The front seals on both of them leaked and blew up on the first. I bought the pumps from advanced auto. I installed the pump the first time and the front seal started smoking and blew out. On the second pump the pump started toleak, then stopped. I turned the wheel and it made a HORRIBLE noise, the turning was also very chunky. I used the pressure hose from a 1978 bronco hose for the high pressure line. I used a clamp on hose for the return. What would cause the god awful noise and BOTH the front seals to blow up? Im really getting sick of this!
I also blew through the high pressure hose with my mouth and was able to blow the fluid through. PLEASE help, I have anothe pump on the way tommorrow and I dont was to blow it up as well.

Unlikely to be a problem with a new line. Is the return line good? This isn`t some odd pump with a different direction of rotation? The pressure and return lines are not switched? There isn`t a check valve in wrong?

Sounds like a problem I had when I did my swap. . .basically the god aweful noise boiled down to not having the belt tight enough. . .quiet as a mouse now and powerful enough I can flip my steering wheel and get it to turn 
Could just be crappy Advance Auto pumps. . .mine came out of a '79 van, is old but nearly perfect. . .

What problem lead to you replacing the pump?
What type of fluid are you using?
What pump are you using?
If the fluid inside the steering gear had crud in it from the previous problem and you didn't thoroughly flush the old fluid out, you are sending the contaminated fluid through the new pump. This could cause self destruction.
There might also be an inline filter in the return hose that you can't see and may be clogged causing a restriction of fluid movement.
Use a hooked tool (pick etc.) to investigate to as whether there is a hidden filter in the return line.

whoops, didn't realized yours was auto tension. My truck is an 87 but was early enough to get the last few carbed 460 out of the factory so mine is v-belt
I wish i could be of more help, I really don't know what might be causing it. . .though, in my 1978 F250 the power steering pump was just the same ol crappy pump type I swapped out of my 87 F250. The Saginaw Pump is found in chevies and ford vans from what I found. . .do you have the right pump?

I'll bet you are getting low quality pumps.
Are you refering to the A-1 Cardone 20-6244.
I have heard that the Cardone pumps suffer from a quality control standpoint.
Keep trying till you get it right.
Did you read this thread: https://www.ford-trucks.com/forums/6...ering-fix.html
I didn't see the year of your truck, but I think most 92 up use MerconIII for steering fluid.
Good luck!
