## Discrepancy

AFTER ENGINE START A LINE SERVICE ATTENDANT NOTICED FUEL COMING FROM THE RIGHT ENGINE COWLING AND LEAKING TO THE GROUND, HE SIGNALED THE PILOTS TO SHUT DOWN. A MECHANIC OPENED THE COWLING, INSPECTED THE ENGINE AND FOUND FUEL TO BE LEAKING FROM THE FUEL CONTROL WHEN PRESSURIZED. THE HMU WAS REMOVED AND REPLACED.
