Description
Universal and easy to work with. The Star Machine vacuum pump regulator allows you to adjust the vacuum in your crankcase to the desired amount. A simple loosening of the jam nut and a turn in or out of that poppet is all that is needed to alter the vacuum. The Star Machine vacuum regulator is superior in design to those that are mounted into the valve cover. With the Star Machine regulator, cold air is released through the regulator its self and not into the engine. A valve cover mounted vacuum regulator allows moisture to get into that engine which is not good at all.
