Narrative:

We were taking off day VFR; weight approximately 117000 pounds. At approximately 90 KTS; the first officer called out fuel filter bypass light on. I rejected the takeoff at approximately 90-100 KTS. I was concerned about an engine failure so I rejected the takeoff. I deselected autobrakes to off and brought the airplane to a stop. The first officer told the flight attendants to remain seated. I spoke with the flight attendants passenger; dispatch; maintenance control; tower; and operations. We ran the brake cooling chart and did not set the parking brake. We requested operations to come out to chock the tires. I taxied the aircraft back to the gate after approximately 45 mins. The human factors side of the equation is the number of takeoffs without incident. This event highlights the need to enforce the mindset of going unless I think the aircraft will not fly. I have an increased respect for the amount of energy it takes to reject a takeoff.

Title: A B737-300 CREW REJECTED A TKOF AT 100 KTS FOR A FUEL FILTER BYPASS WARNING ANNUNCIATION.

Narrative: WE WERE TAKING OFF DAY VFR; WT APPROX 117000 LBS. AT APPROX 90 KTS; THE FO CALLED OUT FUEL FILTER BYPASS LIGHT ON. I REJECTED THE TKOF AT APPROX 90-100 KTS. I WAS CONCERNED ABOUT AN ENG FAILURE SO I REJECTED THE TKOF. I DESELECTED AUTOBRAKES TO OFF AND BROUGHT THE AIRPLANE TO A STOP. THE FO TOLD THE FLT ATTENDANTS TO REMAIN SEATED. I SPOKE WITH THE FLT ATTENDANTS PAX; DISPATCH; MAINT CTL; TWR; AND OPS. WE RAN THE BRAKE COOLING CHART AND DID NOT SET THE PARKING BRAKE. WE REQUESTED OPS TO COME OUT TO CHOCK THE TIRES. I TAXIED THE ACFT BACK TO THE GATE AFTER APPROX 45 MINS. THE HUMAN FACTORS SIDE OF THE EQUATION IS THE NUMBER OF TKOFS WITHOUT INCIDENT. THIS EVENT HIGHLIGHTS THE NEED TO ENFORCE THE MINDSET OF GOING UNLESS I THINK THE ACFT WILL NOT FLY. I HAVE AN INCREASED RESPECT FOR THE AMOUNT OF ENERGY IT TAKES TO REJECT A TKOF.
