Normally, it's open, but when the internal pump goes up, it closes. This can also cause a light or over reactive response in the steering system at highway cruise speeds. Crank Pulley Diameter / Power Steering Pulley Diameter = Pulley Ratio, 2. You can reduce the output pressure of the pump with this regulator. Pressure after 5 minute idle warm-up: 200 psi. A belt and pulley linked to the engine drive the pump. Verify the well pump. Use your file to take about 1/8" off the pin end of the stem (this is precautionary - to prevent the bypass from jamming shut).
