Hi Brian
The bottom port goes to the remote filter and the top port is the return from the filter and into the engine. I didn't use a remote filter. My oil pressure sensors were installed like this because these 2 ports are after the oil filter.
Looks like I never documented the coolant bushing size!! It is either 1/4" to 1/8" NPT or 3/8" to 1/8". Sometimes that plug is very hard to remove.
