## Discrepancy

PILOTS REPORTED HIGHER THAN NORMAL CHT ON CYLINDERS NR 1 AND NR 3 ALONG WITH LOW FUEL FLOW ON CLIMB, IN THE RANGE OF 12 TO 14 GALLONS PER HOUR.  WE HAVE ESTABLISHED AN OPERATIONAL MINIMUM FUEL FLOW OF 16.0 GALLONS IAW HOUR DUE TO OUR EXPERIENCE WITH THESE ENGINE DRIVEN FUEL PUMP ANEROID FAILURES.  ATTEMPTED TO ADJUST PUMP IAW SID97-3 AND MAXIMUM ADJUSTMENT AVAILABLE DID NOT CORRECT LOW FUEL FLOW CONDITION. PUMP REPLACED.
