## Discrepancy

BOTH MAIN TANKS FED WHILE THERE WAS 12000LBS IN CENTER TANKS.  RIGHT MAIN TANK FED FASTER, IMBALANCE OF 2000LBS.  SUSPECT BAD OVERRIDE PUMPS.  FOUND PUMP LEAKING DURING OPS CHECK.  REMOVED PUMP TO REPLACE O-RINGS.  DURING INSTALLATION SHOULDER SCREW BROKE.  NEEDS NEW SHOULDER SCREW AND REINSTALL PUMP.  CHANGED BOTH RT AND LT OJ PUMPS.  OP CHECKS & LEAK CHECK GOOD.
