## Discrepancy

TESTED FUEL PUMP, MOTOR DRIVEN FUEL PUMP REACHED SPECIFIED CALIBRATING VALUES.  WITH HIGHWING TANK CONNECTED TO THE FUEL PUMP INLET PORT, THE NONE DRIVEN FUEL PUMP LEAKS REGARDLESS  THE MIXTURE LEVER POSITION THROUGH THE OUTLET PORT.  WITH MIXTRUE LEVER IN IDLE CUT OFF THE FUEL FLOW IS THE SAME AS IN FULL RICH.  3 TO 4MM/0.012IN TO 0.16IN/ AWAY FROM THE IDLE CUT OFF STOP, THERE IS THE LOWEST FUEL FLOW.
