The different pressure pumps have a by pass spring to keep pressure at specs for each particular pump it is the pumps brain the gears in the pump cant control the pressure. the by pass spring is in control cold or hot!

The by pass for the filter opens letting most oil by pass the filter! the filter does not filter all the oil all the time only about 10 percent during running conditions. If you block off the oil bypass all oil is filtered all the time! If you add a heavier spring the percentage goes up!
