Got the hose sizes, but having a bugger of a time finding a 5/8*5/8*3/8 tee.
I have a detroit setup somewhere. the filters have additives that are designed to break down and neutralize certain situations that can cause damage to the motor over time. designed for making the coolant life extend out for a very long time!
Got it installed. Went really well. Filter was hot-good. Also, I flushed out the heater core in the process. We will have to see what it does.
