In a dry sump reciprocating engine, locating the oil temperature regulator between the scavenge pump outlet and the storage tank is crucial for effective oil management. This positioning allows the regulator to monitor and control the temperature of the returning oil before it enters the storage tank.

When the oil returns from the engine after circulating, it can be quite hot. By positioning the temperature regulator in this area, the system can ensure that any excessively hot oil is cooled adequately before it is stored. This prevents overheating and maintains optimal oil viscosity for efficient engine operation.

In addition, having the regulator in this location allows for better overall temperature management of the lubrication system, helping to prolong engine life and optimize performance.
