Aircraft
Departed with full wing fuel and 4.5k fuel in center tank. Both center pumps were turned on. At level off at FL340 noticed Fuel Config EICAS message; center fuel was at .2 so turned pumps off. Noticed Fuel Config Eicas message remained on. Upon examination of Fuel Panel; noticed that there was 35.5 in left tank; and 39.5 in right tank. Total fuel indicated correctly for fuel used. It appears all center fuel was consumed by right engine. We then balanced fuel and flight was normal from that point on. System was written up in logbook.
A B767-300 pilot reported that center tank fuel was used primarily by the right engine leaving the amount of fuel in the wing tanks unbalanced.
