Narrative:

We took on min fuel to travel, part 91, from sdf to day international. Unknown to me, the totalizer fuel indicator was giving erroneous information. It showed that we had approximately 500 pounds more fuel on the ground than it did after takeoff. So, I decided to immediately return to sdf to check out the problem we arrived without incident. After talking to my dom. We concluded the problem was a low fuel level in the left wing (where the totalizer probe is located). If the probe is not totally submerged it will give false readings, such as we experienced. So, we decided to put on twice as much fuel as needed and see if our theory was correct. It was, and we continued our flight without further delay.

Title: FLC OF SMT JET ACFT RETURNED TO LAND DUE TO A LOW FUEL INDICATION FOR THE PROPOSED FLT.

Narrative: WE TOOK ON MIN FUEL TO TRAVEL, PART 91, FROM SDF TO DAY INTL. UNKNOWN TO ME, THE TOTALIZER FUEL INDICATOR WAS GIVING ERRONEOUS INFO. IT SHOWED THAT WE HAD APPROX 500 POUNDS MORE FUEL ON THE GND THAN IT DID AFTER TKOF. SO, I DECIDED TO IMMEDIATELY RETURN TO SDF TO CHK OUT THE PROBLEM WE ARRIVED WITHOUT INCIDENT. AFTER TALKING TO MY DOM. WE CONCLUDED THE PROBLEM WAS A LOW FUEL LEVEL IN THE L WING (WHERE THE TOTALIZER PROBE IS LOCATED). IF THE PROBE IS NOT TOTALLY SUBMERGED IT WILL GIVE FALSE READINGS, SUCH AS WE EXPERIENCED. SO, WE DECIDED TO PUT ON TWICE AS MUCH FUEL AS NEEDED AND SEE IF OUR THEORY WAS CORRECT. IT WAS, AND WE CONTINUED OUR FLT WITHOUT FURTHER DELAY.
