## Discrepancy

IND  FLT 634  EN ROUTE, LAS TO PHL.  THE FLIGHT CREW NOTICED A 2400 LB PER HOUR FUEL LOSS.  THE FIRST OFFICER CONFIRMED THAT THERE WAS A VAPOR COMING FROM THE RIGHT ENGINE PYLON AREA.  THE CREW DIVERTED TO IND AND LANDED WITHOUT FURTHER INCIDENT.  MAINTENANCE REPLACED O-RINGS GOING ON THE FUEL TUBE FROM THE FUEL FLOW REGULATOR TO THE HIGH PRESSURE PUMP INLET.  AIRCRAFT LEAK CHECKS OK.
