Ok, so was having issues with the steering when driving no problems, but while idling there was no power steering, new pump, new gear box, belt is tight and new ext.. Mechanic has me running trans. fluid in it.
So I decided to try a new pump, did that according to the chitons book, bleed it, worked great for about 2 blocks, then the exact same thing is happening now.
Anybody else having this issue???
Any help??
Thanks in advance

Why aren't you running power steering fluid in it?

Mechanic told me not too, but i flushed it today and put power steering fluid in and so far so good.

ATF dextron is what my steering grearbox rebuilder told me to use and that is what I use. Also it states in the manual you can use it.

Mine is the original pump, original cap, and original high pressure hose. I have owned the ps assembly since ’77. The po bought the 97k mile car/pump in ’74 from the original owner, and the car was such a cream puff, I doubt that the ps pump was ever topped off. The pump has never had a drop of ps fluid in it, probably the reason why it’s still alive 750k miles later.

wrong pic

The 7’s and 8’s should have the identical ps cap, and if it has another style cap, such as use p/s fluid, it’s a replacement, not an original.

More original p/s caps, all of that era.

Interesting. I've never actually looked at what is on my cap. It doesn't leak so I've not had to top it up.

This [censored] thing, ran great for 2 days, and now no power steering when at idle!

While there is no power steering shut it off and crack the pressure side open (put some rags on it). Restart and be ready to shut it off. New doesn't mean good. I bet it is your pump.
