Narrative:

About 200 mi east of den, the #2 flight attendant advised me that passenger were concerned about fuel leaking from the left wing. I went back and observed we did have fuel leaking from the overwing boost pump access panel. I had been running a fuel log and recomputed our fuel used versus block and fuel remaining. I showed a 200 pound difference. I contacted flight control via commercial radio and relayed our problem. Having 24300 pounds fuel remaining and only 1 1/2 hours to fly to rno, even with a loss rate of 200 pounds per hour, we estimate an ending fuel of 15000 pounds remaining on arrival at rno. The dispatcher and I agreed continued flight to rno was acceptable. I continued to compute block fuel versus fuel remaining and updated flight control over slc. On arrival in rno we had 14500 pounds, 500 pounds less than planned due to unforecast 120 KT winds from slc to rno. Maintenance found loose screws and are working on clearing the write-up. Note: we ran the fuel leak checklist and it did not address our problem. Callback conversation with reporter revealed the following information: the reporter stated the aircraft was an MD90 and was only a few days old. The reporter said the leak was located on the left wing upper surface inboard fuel pump access plate and was caused by the fasteners on the plate being loose. The reporter stated the loss of fuel did not cause any diversion.

Narrative: ABOUT 200 MI E OF DEN, THE #2 FLT ATTENDANT ADVISED ME THAT PAX WERE CONCERNED ABOUT FUEL LEAKING FROM THE L WING. I WENT BACK AND OBSERVED WE DID HAVE FUEL LEAKING FROM THE OVERWING BOOST PUMP ACCESS PANEL. I HAD BEEN RUNNING A FUEL LOG AND RECOMPUTED OUR FUEL USED VERSUS BLOCK AND FUEL REMAINING. I SHOWED A 200 LB DIFFERENCE. I CONTACTED FLT CTL VIA COMMERCIAL RADIO AND RELAYED OUR PROB. HAVING 24300 LBS FUEL REMAINING AND ONLY 1 1/2 HRS TO FLY TO RNO, EVEN WITH A LOSS RATE OF 200 LBS PER HR, WE ESTIMATE AN ENDING FUEL OF 15000 LBS REMAINING ON ARR AT RNO. THE DISPATCHER AND I AGREED CONTINUED FLT TO RNO WAS ACCEPTABLE. I CONTINUED TO COMPUTE BLOCK FUEL VERSUS FUEL REMAINING AND UPDATED FLT CTL OVER SLC. ON ARR IN RNO WE HAD 14500 LBS, 500 LBS LESS THAN PLANNED DUE TO UNFORECAST 120 KT WINDS FROM SLC TO RNO. MAINT FOUND LOOSE SCREWS AND ARE WORKING ON CLRING THE WRITE-UP.
