Narrative:
Right hydraulic system failure followed by fuel leak. Secured right engine diverted to ZZZ. Made uneventful single engine landing. No passenger evacuation. Callback conversation with reporter revealed the following information: the reporter stated in cruise they received an EICAS hydraulic warning and noted the hydraulic quantity rapidly loss and shortly afterward the low pressure warning. The reporter said while observing the fuel quantity indication it was noted the right wing quantity was decreasing rapid and it was decided to shut down the right engine. The reporter stated an emergency was declared and diversion to a suitable airport started. The reporter said on the ground a large amount of fuel was observed leaking from the pylon where it joins the leading edge of the wing. The reporter stated maintenance reported the hydraulic line and fuel line had broken where it passes from the wing and enters the pylon through a rubber vibration isolator or grommet. The reporter said the grommet was found missing and a check of the fleet was made with results unknown.

Title: A B757-200 IN CRUISE DECLARED AN EMER AND DIVERTED DUE TO LOSS OF R HYD SYSTEM AND FUEL LEAK. CAUSED BY FAILED HYD AND LINES.
Narrative: RIGHT HYDRAULIC SYSTEM FAILURE FOLLOWED BY FUEL LEAK. SECURED R ENGINE DIVERTED TO ZZZ. MADE UNEVENTFUL SINGLE ENGINE LNDG. NO PAX EVACUATION. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE RPTR STATED IN CRUISE THEY RECEIVED AN EICAS HYDRAULIC WARNING AND NOTED THE HYD QUANTITY RAPIDLY LOSS AND SHORTLY AFTERWARD THE LOW PRESSURE WARNING. THE RPTR SAID WHILE OBSERVING THE FUEL QUANTITY INDICATION IT WAS NOTED THE R WING QUANTITY WAS DECREASING RAPID AND IT WAS DECIDED TO SHUT DOWN THE R ENGINE. THE RPTR STATED AN EMER WAS DECLARED AND DIVERSION TO A SUITABLE ARPT STARTED. THE RPTR SAID ON THE GND A LARGE AMOUNT OF FUEL WAS OBSERVED LEAKING FROM THE PYLON WHERE IT JOINS THE LEADING EDGE OF THE WING. THE RPTR STATED MAINT RPTED THE HYD LINE AND FUEL LINE HAD BROKEN WHERE IT PASSES FROM THE WING AND ENTERS THE PYLON THROUGH A RUBBER VIBRATION ISOLATOR OR GROMMET. THE RPTR SAID THE GROMMET WAS FOUND MISSING AND A CHK OF THE FLEET WAS MADE WITH RESULTS UNKNOWN.
