power steering pump question

HI ALL
The GM power steering pump quit pumping.
I have a GM pump on mustang II rack.
The pump I have has a pressure valve.
I did not know the year the pump was so I bought a 77 pump.
The pump is the same all but ,when I removed the line fitting there was no pressure valve.
My question is what years did the pump have the pressure valve?
I need the valve so I can reduce the pressure.
The steering is a little sensitive.
THANKS BOBBY

Use your old one. It unscrews from the pump body.

Take the pressure valve off the new pump and stretch the spring inside it to reduce pressure. Reinstall. If the pressure is too low, than place a 4mm washer under hte spring to increase the tension. Or just install a spring of choice.

If that doesn't work then I need a picture.

I removed the line fitting from the rebuild pump and there is no pressure valve under the fitting.

Hey JG, that was some good info, Thanks

I will store that for further use.

Now I can ID all the old parts I have around here for GM pumps
Thanks again.

46, which Rack do you have, how many turns from lock to lock, that will make a difference on how sensitive it is also.
