Narrative:

In sum: this report concerns a fuel indication write-up on a convair 600. I checked the indicator in the cockpit, and the left gauge was showing 1900 pounds, and the right gauge was showing 1700 pounds. I dipped the fuel tanks, and the left tank was showing 210 gallons while the right tank was showing 220 gallons. However, I did not make a logbook entry detailing which indicator was reading incorrectly, I just copied down what the pilot had previously written in the logbook. The aircraft MEL states that only 1 correct fuel quantity indicator is required for the aircraft to be airworthy. I told the pilots that I was deferring the left indicator, and that they would need to dip the fuel tanks when preflting the aircraft.
