I am going to be changing oil very shortly and will be installing either the by-pass or dual remote system. I have been reading the past threads and saw some issues with the dual remote as far as noise and oil pressure. I could find nothing from anyone that was running it and was completely happy, but maybe I overlooked something. Also from some of the pictures on the Amsoil site some of the dual system on the Dodge/Cummins trucks had some kind of pump looking device on the filter head with a solenoid valve on the side. Anyone know what this is? Looking for cold hard facts before I buy although opinions welcome too! Also, the reason I am considering the dual system is it puts everything in one location. Thanks
