An Mopardude318, if I may suggest this.... .put in the new HV pump first and don't change to the 90 degree adapter until a 2nd step, just to see the difference of the pump by itself.
it is the Napa 1068, shorter filter, not 6 inches long.
What I can do today, is put the 90* adapter on right now, with the same pump I have now, and take note and a video of the oil pressure at that location as well. then switch right back. I have everything, it'll take me no time.
