Max Pressure of Stock 5.4 3v Oil Pump?
What is the maximum pressure you can expect a stock 5.4L 3v oil pump to deliver? It's limited by the pressure relief spring, correct?

Yes the pressure is limited by the relief spring. I would expect it to open at about 60 psi, but that's kind of a generic number and I don't know where to find the spec., if it even exists.
