## Discrepancy

DURING CLIMB, FUEL STARTED VENTING FROM THE RIGHT WING TIP.  CLOSED CROSSFEED VALVES AND THE VENTING STOPPED.  AIRCRAFT DIVERTED TO SEA AND LANDED WITHOUT INCIDENT.  SECURED SURGE TANK DRAIN LINE FITTING AT NR 4 PYLON RIB AND REPLACED NR 3 FUEL BOOST PUMP DUE TO LACK OF PRESSURE ON RETURN MANIFOLD.  OPERATIONAL CHECK GOOD.
