PRESSURE PROBE WAS FOUND TO HAVE AN INSUFFICIENT AMOUNT OF BRAZE MATERIAL AT THE JOINT WHERE THE TUBE AND ELBOW ARE JOINED TOGETHER.  IMPORTANT: MFG ISSUED AN ALERT CEB A-1374 IN MAY 2000 ADDRESSING THIS PROBLEM WITH THE PREVIOUS PN 6850921.  MFG THEN RELEASED PN 23073525 TO REPLACE THE OLD P/N WITHIN 300 HOURS OF FLIGHT TIME.
