Narrative:

In cruise flight, passenger reported liquid seeping from left aft fuel tank boost pump cover. First officer went back to inspect and confirmed the fluid seepage. Spoke to technician on common radio frequency and they indicated that as long as seepage was minimal and not a leak confirmed on the fuel gauges to continue normally to destination and seek maintenance attention. Followed recommendation and continued normally to smf after turning off the wing tank heater system and not noticing any perceived fuel loss or burn en route after the discovery. Guidance in S80 operations manual was only to land at nearest suitable airport if a leak was confirmed which in this case I deemed it was not. First officer also established that seepage had ceased prior to descent. As a precaution had fire trucks follow us into the gate at smf after landing. No further seepage was reported through gate arrival. Maintenance confirmed that the seepage was within limits after the tanks were filled again, prior to dispatching us for return to dfw. As a precaution fuel tank heater system was placarded inoperative as well. After this experience, I recommend better guidance for this situation in the S80 operations manual part 1 and if possible the S80 MEL.

Narrative: IN CRUISE FLT, PAX RPTED LIQUID SEEPING FROM L AFT FUEL TANK BOOST PUMP COVER. FO WENT BACK TO INSPECT AND CONFIRMED THE FLUID SEEPAGE. SPOKE TO TECHNICIAN ON COMMON RADIO FREQ AND THEY INDICATED THAT AS LONG AS SEEPAGE WAS MINIMAL AND NOT A LEAK CONFIRMED ON THE FUEL GAUGES TO CONTINUE NORMALLY TO DEST AND SEEK MAINT ATTN. FOLLOWED RECOMMENDATION AND CONTINUED NORMALLY TO SMF AFTER TURNING OFF THE WING TANK HEATER SYS AND NOT NOTICING ANY PERCEIVED FUEL LOSS OR BURN ENRTE AFTER THE DISCOVERY. GUIDANCE IN S80 OPS MANUAL WAS ONLY TO LAND AT NEAREST SUITABLE ARPT IF A LEAK WAS CONFIRMED WHICH IN THIS CASE I DEEMED IT WAS NOT. FO ALSO ESTABLISHED THAT SEEPAGE HAD CEASED PRIOR TO DSCNT. AS A PRECAUTION HAD FIRE TRUCKS FOLLOW US INTO THE GATE AT SMF AFTER LNDG. NO FURTHER SEEPAGE WAS RPTED THROUGH GATE ARR. MAINT CONFIRMED THAT THE SEEPAGE WAS WITHIN LIMITS AFTER THE TANKS WERE FILLED AGAIN, PRIOR TO DISPATCHING US FOR RETURN TO DFW. AS A PRECAUTION FUEL TANK HEATER SYS WAS PLACARDED INOP AS WELL. AFTER THIS EXPERIENCE, I RECOMMEND BETTER GUIDANCE FOR THIS SIT IN THE S80 OPS MANUAL PART 1 AND IF POSSIBLE THE S80 MEL.
