Narrative:
The [electronic fuel monitoring system] showed that we were out of tolerance on the high side for gallons boarded. I asked for the fueler to come speak to us. When I showed him the [electronic fuel monitoring system] and asked him to explain it; he was unable to do so. He knew nothing about gallons tolerance; and he seemed confused when I asked him if perhaps the density was incorrect. He said he just pumped in enough gallons to give us the fuel we requested. At that point I asked him to have his supervisor come speak to us. The supervisor told us that the fueler had used an incorrect density number. The fueler used 6.75; and the actual density was 6.67. I asked how this could happen. He replied that the density number is just typed into the device the fueler uses to transmit the fuel uplift information; and that it isn't updated very often. He also said that the same thing occurred on the previous day.I don't understand this answer at all. How can the person pumping fuel not understand the concept of fuel density? And how can the density number be entered into an electronic transmission device and not updated with some frequency? This is my second [report] this year about fueling issues in bos. There might be some training and/or process issues going on here.
