What was found
DURING CRUISE THE PILOT RECEIEVED A CAS MESSAGE NOTING A FUEL IMBALANCE BETWEEN THE LH AND RH WING. THE FUEL FLOW FROM THE RIGHT HAND TRANSFER SYSTEM WAS NOT KEEPING UP WITH THE FUEL FLOW FROM THE LH FUEL TRANSFER SYSTEM INDICATING LOW PRESSURE FROM THE MOTIVE FLOW FROM THE RIGHT HAND ENGINE DRIVEN FUEL PUMP. THE RIGHT HAND ENGINE DRIVEN FUEL PUMP WAS REPLACED WITH A OVERHAULED UNIT AND THIS RESOLVED THE ISSUE WITH THE FUEL IMBALANCE. THE PLANE WAS RETURNED TO SERVICE AND COMPLETED SEVERAL FLIGHTS WITH NO FURTHER ISSUES.
