There actually is no OilPressure in the Sump ~ OilPressure Exists Only in the Plumbing/Galleys

Between the Pump & all the Parts&Bits&Pieces that need Lub'ing & so therefore that is also where the

OilPressureSensors/Senders are located ~ Aeration of the the Oil causes AirBubbles to get mixed into

the Oil & because Air is Compressible a Drop in OilPressure can occur ~
