Narrative:
Frequency: 135.77, FL310, ZLC. Approximately 100 mi southeast mtu. Approximately 2 hours 30 mins into flight, flight engineer reported that #1 and #2 fill valves had closed while auxiliary fuel tank feeding, resulting in fuel imbal well out of limits. Rebalanced fuel and corrected fuel panel in accordance with operations manual. Contacted dispatch and maintenance to confirm ok to continue to destination. No abnormal flight controls. Wrote up in E6 logbook. Imbal created rather quickly and shows importance of captain checking tank gauges as well as totalizer as backup to flight engineer.

Title: A DC10 ENRTE TO HAWAII DEVELOPS A FUEL IMBAL DURING XFEEDING WHEN 2 FILL VALVE CLOSED WITHOUT THE CREW INITIALLY OBSERVING THAT FACT.
Narrative: FREQ: 135.77, FL310, ZLC. APPROX 100 MI SE MTU. APPROX 2 HRS 30 MINS INTO FLT, FE RPTED THAT #1 AND #2 FILL VALVES HAD CLOSED WHILE AUX FUEL TANK FEEDING, RESULTING IN FUEL IMBAL WELL OUT OF LIMITS. REBALANCED FUEL AND CORRECTED FUEL PANEL IN ACCORDANCE WITH OPS MANUAL. CONTACTED DISPATCH AND MAINT TO CONFIRM OK TO CONTINUE TO DEST. NO ABNORMAL FLT CTLS. WROTE UP IN E6 LOGBOOK. IMBAL CREATED RATHER QUICKLY AND SHOWS IMPORTANCE OF CAPT CHKING TANK GAUGES AS WELL AS TOTALIZER AS BACKUP TO FE.
