## Discrepancy

AT 800 RPM THE FUEL PRESSURE DROPS BELOW MINIMUM AND THE LOW PRESSURE LIGHT CAME ON AT IDLE.  SYSTEM WAS CHECKED AND FOUND THAT THE PUMP OUT PUT WAS LOW.  PUMP REMOVED AND A NEW PUMP INSTALLED.  GROUND RUN AND FINAL ADJUSTMENTS TO THE PUMP WERE MADE.  OPERATIONAL CHECK OF THE PUMP AT IDLE AND MAX RPM CHECKED NORMAL.  PART WAS SENT FOR WARRANTY.
