MD-11 Captain reported fuel quantities were less than expected compared to the fuel log and FMS estimation and performed a QRH procedure that stopped the leaking.
What is ASRS?
The Aviation Safety Reporting System is NASA's voluntary, confidential, non- punitive incident-reporting system, established 1976. Pilots, controllers, dispatchers, and maintenance technicians file reports describing safety- relevant events. NASA de-identifies every report before adding it to the public database. Reports are not investigated by NASA, the FAA, or the NTSB — they represent the reporter's perspective.
Pilot narrative
Verbatim from the de-identified NASA record. First-person account by the
reporter. NASA strips identifying details (names, company, specific time);
anonymization placeholders are ZZZ,
X, Y.
Level 2 fuel quantity used check alert. Fuel quantities showed 4500 lb. less than expected according to the fuel log as well as a rapid decrease on the FMS estimated fuel on board at destination. The QRH procedure stopped the leaking. The leaks seemed to happen while the autocontroller was transferring fuel to the wing tanks for balancing purposes. Diverted to ZZZ. Cause [was] alert driven.

ASRS reports are voluntarily submitted, de-identified by NASA, and represent the reporter's perspective. The presence of reports on a topic cannot be used to infer prevalence in the National Airspace System. The authoritative source is the NASA ASRS Database Online at asrs.arc.nasa.gov ↗.
