Mine is 1.4 pressure and during the hot summer can be even lower with hot oil. For the summer I've got an external oil cooler to keep the oil from overheating. Not so sure that a new pump is going to make much difference as the pressure is generated by the clearances around the crank bearing shells. If these are a bit worn then there is less resistance that is needed to generate the pressure.

"Mine is 1.4 pressure" at idle. At higher speeds it will go to 3.5-4 pressure. Bella is approaching 160,000 miles though.
