## Discrepancy

(CAN) WHEN BOOST PUMPS WERE ACTIVATED, FUEL WAS SEEN COMING OUT OF THE ACFT ENGINE DRAIN.  ONCE THE ACFT STARTED, THE LEAK WOULD STOP.  ENGINE MFG KNOWS ABOUT THIS ISSUE AND SAYS THAT THE SEALS ARE POOR.  WE HAVE HAD THIS ISSUE WITH THIS FCU AND 2 OTHERS WITH A TOTAL OF 5 SEALS BEING REPLACED AFTER THE INITIAL O/H. AT THIS POINT IN TIME WE ARE WONDERING IF THIS A SAFETY CONCERN.  ENGINE MFG HAS INDICATED THAT THIS IS NOT AN ISSUE IF THE LEAKS STOP ONCE THE ACFT HAS STARTED.
