Maybe Bob G could post some pics of his oil filter setup, would like to see, for sure.
When I set mine up I welded two 3\8 couplers to the bottom of the oil pan, for pickup and return
and used a 120v micro gear pump,(ebay cheap) coupled to an thermol snap disc so it comes on after the oil has heated. plus manual (on) override.
Oil out of the pan ,thru oil coooler mounted in exhaust air of the ST12, thru the pump and on to a PH8A type spin on housing and back to bottom of oil pan,
When I want to change the oil I take off the filter, plug into grid 120v and flip the switch, I do still pull the magnetic drain plug to check and clean it,
BTW mine is Changfaoid, a Xing Dong
That way I can tell the wife I have to go outside to check my Dong.
The whole thing is mounted on an reclaimed 3 wheel welding cart, for quick deployment after a Hurricane,
also have 5000 - 10000 watt inverter for power during the storm before safe deployment of genset is possible.
That inverter will carry my one heavy surge load for my 6\1 screw the power company project, now nearing compleation for summer A\C needs.
6\1 is splash lube only, so installed simular pump setup on it. without the cooler

Henery,
be sure to take off the pan and clean it nice before any runs.and don't run much with out a load.
I had my R180 7.7 coupled to a large turbo axial fan for loading, diesel powered shop fan
