## Discrepancy

WITH A HIGHWING TANK CONNECTED TO THE FUEL PUMP INLET PORT, THE NONE DRIVEN FUEL PUMP LEAKS REGARDLESS THE MIXTURE LEVER POSITION.  WITH THE MIXTURE LEVER IN IDLE CUT OFF, THE FUEL FLOW IS THE 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.
