I ran a 2 cooler set up, but with a 2 port remote filter with no gauges. Most guys dont run gauges. maybe a gear ind. Anyway there wanys to run the return from the coolers to the main oil galley on the left side of the motor above the pan. Then pull PSI from the center of the puck on the back. So call HANK SCOTT or anythere builder and tell what you are trying to do. It is just had to do this in a message board
