Review on ACDelco GM Original Equipment 19244519 Fuel Pump Switch with Engine Oil Pressure Gauge Sensor by Gary Ferguson

First installed by a non-OEM from an auto parts network that only reads half the actual pressure causing the low oil pressure gauge to flicker at idle. Went back to the store and installed this one for 30% off which showed the correct print. Once again, a chain store burned an inferior branded part at an inflated cost that came very close to the cost of a GM dealership. They list part of AC Delco but really just have their higher margin private label.
