## Discrepancy

HIGHWING TANK CONNECTED TO THE FUEL PUMP INLET PORT.  THE NONE DRIVE FUEL PUMP LEAKS REGARDLESS THE MIXTURE LEVER POSITION.  WITH MIXTURE LEVER IN IDLE CUTOFF, FUEL FLOW IS SAME AS IN FULL RICH.  3 TO 4 MM/0.012IN TO 0.016IN AWAY FROM THE IDLE CUT OFF STOP, THERE IS THE LOWEST FUEL FLOW AT ALL.
