TECHNICIANS INSPECTED THE ENG & FOUND THE CAP HAD SEPARATED FROM THE HIGH PRESS RELIEF VLV, WHICH RESULTED IN THE LOSS OF FUEL PRESS. ONCE THE FUEL PUMP COULD BE REMOVED, THE HIGH PRESS RELIEF VLV WAS DISASSEMBLED FOR FURTHER EXAMINATION. A FRACTURE IN THE THREADS OF THE RELIEF VLV BODY AT THE CAP END WAS DISCOVERED.
