Replumbing the coolant to place the pressure cap on a true expansion tank on the pump suction seems to be desirable. Thus, keeping the pump suction at a constant, not decreasing pressure with increasing flow. Turbulence in the pump inlet "elbow" would also contribute to cavitation and using a vane in that elbow be beneficial.
