The pilot reported that prior to takeoff he drained the main lower sump, but not the wing sumps, as was company policy. The pilot stated that he was told by the mechanic that “constant use of the wing sumps causes them to leak, and also causes damage to the fuel cells that is hard to repair.” The pilot also reported that the airplane had been fueled a few days prior to the flight from a 55 gallon barrel by an electric pump at the company’s fueling facility.
