Has anyone looked into how to go about adding an independent oil pressure gauge (perhaps inline with one of the cooler fittings? where would be most appropriate? Post-cooler?) I think (someone correct me if I'm wrong) that with the standard sandwich plates, the basic flow is pan -> pump -> cooler -> filter -> top of engine -> drain back to pan, right?
