Oil Pressure - it's N O R M A L

My dad has a 1992 Chinook Class B RV, built on a 1992 Ford E-350 (van) chassis. The chassis is powered by a 7.3 liter IDI diesel. Dad, disliking idiot lights, relies on the factory set of gauges this van provides. However, some questions arose about what the oil pressure gauge was telling. A mechanical oil pressure gage was installed, and was a bit enlightening.
