      is this regulator spring mod advisable without the pump gear extension mod. i understand
      they are changing the pump driver pins from roll formed to solid shaft
      and extending the gear teeth to increase flow and pressure by the pump alone.
      one would assume with the spring only you are only putting gallery pressure
      back to where it should be originally assuming the older spring settup is allowing
      blowdown. is the cheaper fix now for low pressure but is the pump a ticking
      hazard

      Here are the part numbers and approximate cost. It is recommended whether you get
      the extended TBO or not. It is just better than the old ball bearing.
      
      Cap screw 841-983  $31.41 (Longer shoulder and harder metal)
      
      Spring  838-122  $7.81
      
      oil pressure regulator cone  857-230  $30  (completely different from the ball
      bearing) looks like a mushroom with a hole in the top.
