get a manual oil pressure check to verify.
if it is accurate, then you may have bearings that may have too much play. before you spend a lot of money on the pump, you need to be sure that the rest of the motor is in good shape. have a shop verify this for you first.

its simle it should be under the motor and you simple unskrew the old one and screw in the new
