Narrative:
During takeoff roll at about 100-110 KTS; we got a 'master caution' light for a 'left fuel filter bypass.' captain decided to abort the takeoff -- stopping on centerline about 3000 ft of runway remaining. Passenger told to remain seated. Consulted brake cooling charts and filter by-pass checklist. Taxied back to gate for maintenance. This occurred on the last leg of a 14 hour duty day. Fatigue played a large role in the captain's decision making and reaction time. We are trained that it's usually safer to continue the takeoff for an amber light of this nature. Yet he aborted. Duty days of this length are extremely unsafe. Thankfully; the WX was good.
