Power steering pressures

The FSM I have says the 5.7 pump should put out 1490-1590 psi. A 6.1 pump should be 1640-1740 psi.

I would find a FSM or similar and get the expected pressure for the pump that was originally in your Dakota and compare it to that.

If they are different by a bunch, you can swap the pressure relief in the pump to get it closer. Look up DIYHemi on YouTube, they have a video on it.
