## Discrepancy

DURING AIRCRAFT 100 HOURS INSPECTION, THE TECHNICIAN DISCOVERED A BLUE COLORED TRACE OF FUEL ORIGINATING FROM THE FUEL PUMP LOW-METERED ADJUSTMENT SCREW.  PRESSURIZED THE FUEL SYSTEM AND NOTICED MORE FUEL LEAKING FROM THE ADJUSTMENT SCREW OF THE FUEL PUMP.  THE TECHNICIAN REPLACED THE FUEL PUMP MECHANISM AND RE-PRESSURIZED THE FUEL SYSTEM, NO LEAKS FOUND.
