The Boeing 737 carrying 93 passengers and six crewmembers left Mineta San Jose International Airport at 6:25 a.m. and landed safely at SFO around 7:30 a.m., Delta spokesman Anthony Black said.
Black said the emergency landing was made after a light came on indicating there was a fuel transfer problem.
However, after passengers exited the plane, a maintenance crew found that the light indicator system was malfunctioning, not the fuel system, Black said.
The flight was canceled and passengers were reassigned to other flights.
