After climbing out; discovered right fuel gauge and totalize 'blank.' Called Dispatch and Maintenance and agreed to land at a nearby divert airport; since we didn't know if this was the problem or a symptom of a bigger fuel problem. Was just this gauge out; or did we lose fuel from the right side also? The only gauge to show fuel was the left side approximately 9;600 LBS (that's not enough to go to our filed destination). Declared emergency and went to the divert airport. On visual approach to Runway XXL; TCAS reported an airplane off our right. This aircraft was landing on Runway XXR. The copilot was flying and had him in sight. TCAS told us to climb; which we did. Copilot always had the aircraft in sight; but since TCAS said climb; we did climb. After conflict resolved we continued on the approach and landed uneventfully. Had Maintenance determine it was just a gauge problem. Had it deferred and placard. [We] had quantity check by lowering the fuel sticks. Got new release then went to our filed destination.
Need some guidance in QRH for this fuel quantity indicator failure.
A B757 crew found the right fuel gauge and totalizer both blank and not knowing the problem declared an emergency and diverted for a maintenance examination; which determined the cause to be a gauge failure.
