## Discrepancy

PILOT REPORTED FUEL SMELL DURING TAXI / RUN UP.  AIRCRAFT RETURNED TO PARKING FOR MAINTENANCE.  INSPECTION REVEALED FUEL RESIDUE ON FIREWALL BEHIND ELECTRIC FUEL PUMP, NOSE GEAR WHEEL WELL AND BELLY. ELECTRIC FUEL PUMP REMOVED.  INSPECTION OF PUMP REVEALED INTERNAL PUMP TO MOTOR SEAL LEAKING.  FURTHER EXAMINATION REVEALED CLOGGED (MUD DOBBERS) OVERFLOW DRAIN LINE CAUSING FUEL TO BACK UP INTO MOTOR.  THERE WAS ALSO EVIDENCE OF A SMALL FIRE ON BELLY THAT SELF EXTINGUISHED FROM AIRFLOW / PROP BLAST. ELECTRIC FUEL PUMP WAS RECENTLY OVERHAULED WITH ONLY 160 HOURS TIME IN SERVICE.
