## Discrepancy

(CAN) PILOTS REPORTED A PROBLEM OF SLOW TO NO FUEL TRANSFER ON PORT SIDE OF FUEL SYSTEM.  UPON TROUBLESHOOTING THE SYSTEM, FOUND THE RESTRICTOR FROM THE TEE RESTRICTOR P/N 50-921592 HAD BECOME DEBONDED AND TRAVELLED DOWN STREAM TO THE NEXT TEE FITTING AND BECAME LODGED.  THIS RESTRICTED THE LINE AND LIMITED THE FLOW OF FUEL FROM THE TEE FITTING TO THE NACELLE TANK CAUSING THE SLOW FUEL TRANSFER PROBLEM.
