HI I changed my oil pump from the “41-48” type back to the “37-40” flat pump type. The “37-40” pump has 10PSI at idle and 10PSI at high RPM. Is this right? The old one “41-48” had 7PSI at idle and 35PSI at high RPM. Do I need the higher PSI at higher RPM or is it OK the way it is :?:

Thanks for any help
Steven G
