During taxi out to runway 14L at iah, the #2 fire t-handle illuminated and a master warning annunciator was flashing. The first officer and I both looked at the annunciator panel (fire loop annunciator) for a possible false indication. None was seen. I asked the first officer to contact ATC, tell them our position and that we have a fire indication for #2 engine and to roll the fire equipment. While he transmitted with ATC, I taxied the BE1900D into the runway 14L runup pad. I started the memory engine fire/shutdown checklist and the t- handle was still illuminated. I asked the first officer if he could see any smoke or fire around the engine. He said 'no' and I told him to blow the bottle. He said he could see halon ('white stuff') coming out of #2 nacelle. I told him to start an evacuate/evacuation out the main cabin door and to put the people in the grass away from the aircraft. I completed the aircraft securing checklist, made sure the plane was empty, and went over to where the passenger and first officer were standing. By then the fire equipment was arriving and getting into position. I told the fireman the problem and they checked around the #2 engine for fire/smoke. At that point, the fireman discovered fuel leaking from the back of the nacelle and dripped onto the ground. I called our operations/dispatch, reported the incident, asked for a passenger bus, and for maintenance to come out with a tug. The aircraft was taken to the maintenance hangar and rivets were replaced in the wet fuel tank. Callback conversation with reporter revealed the following information: the reporter stated the aircraft was a beech 1900D and the engine fire warning did not appear to be a false warning. The reporter said maintenance did not find any evidence of a fire but replaced a faulty engine fire loop assembly and also corrected the right wing tank fuel leak.

Title: A BEECH 1900D ON TAXI OUT DECLARED AN EMER DUE TO A #2 ENG FIRE WARNING CAUSED BY A FAULTY FIRE WARNING LOOP ASSEMBLY.
Narrative: DURING TAXI OUT TO RWY 14L AT IAH, THE #2 FIRE T-HANDLE ILLUMINATED AND A MASTER WARNING ANNUNCIATOR WAS FLASHING. THE FO AND I BOTH LOOKED AT THE ANNUNCIATOR PANEL (FIRE LOOP ANNUNCIATOR) FOR A POSSIBLE FALSE INDICATION. NONE WAS SEEN. I ASKED THE FO TO CONTACT ATC, TELL THEM OUR POS AND THAT WE HAVE A FIRE INDICATION FOR #2 ENG AND TO ROLL THE FIRE EQUIP. WHILE HE XMITTED WITH ATC, I TAXIED THE BE1900D INTO THE RWY 14L RUNUP PAD. I STARTED THE MEMORY ENG FIRE/SHUTDOWN CHKLIST AND THE T- HANDLE WAS STILL ILLUMINATED. I ASKED THE FO IF HE COULD SEE ANY SMOKE OR FIRE AROUND THE ENG. HE SAID 'NO' AND I TOLD HIM TO BLOW THE BOTTLE. HE SAID HE COULD SEE HALON ('WHITE STUFF') COMING OUT OF #2 NACELLE. I TOLD HIM TO START AN EVAC OUT THE MAIN CABIN DOOR AND TO PUT THE PEOPLE IN THE GRASS AWAY FROM THE ACFT. I COMPLETED THE ACFT SECURING CHKLIST, MADE SURE THE PLANE WAS EMPTY, AND WENT OVER TO WHERE THE PAX AND FO WERE STANDING. BY THEN THE FIRE EQUIP WAS ARRIVING AND GETTING INTO POS. I TOLD THE FIREMAN THE PROB AND THEY CHKED AROUND THE #2 ENG FOR FIRE/SMOKE. AT THAT POINT, THE FIREMAN DISCOVERED FUEL LEAKING FROM THE BACK OF THE NACELLE AND DRIPPED ONTO THE GND. I CALLED OUR OPS/DISPATCH, RPTED THE INCIDENT, ASKED FOR A PAX BUS, AND FOR MAINT TO COME OUT WITH A TUG. THE ACFT WAS TAKEN TO THE MAINT HANGAR AND RIVETS WERE REPLACED IN THE WET FUEL TANK. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE RPTR STATED THE ACFT WAS A BEECH 1900D AND THE ENG FIRE WARNING DID NOT APPEAR TO BE A FALSE WARNING. THE RPTR SAID MAINT DID NOT FIND ANY EVIDENCE OF A FIRE BUT REPLACED A FAULTY ENG FIRE LOOP ASSEMBLY AND ALSO CORRECTED THE R WING TANK FUEL LEAK.
