Pump gears are pretty basic. If clearances are in spec, pressure problems won't be a gear/pocket issue. I think you either have a sending unit issue, a relief not up to par, or a suction side issue.
Powerstrokes back in the day had an issue with a suction side seal. Ford recommended overfilling the pan to the point of getting the level above the suction seal just as a diagnostic to see if problems went away. You might can do this with the rear end jacked way up to get the oil level higher in the front of the pan, too.
