A B722 CREW; DEPARTING SFB; DISCOVERED AT 12000 FT THEY WERE SHORT OF FUEL.

Narrative

AFTER COMPLETING ALL CHKLISTS; FLT DEPARTED SFB ENRTE ABC. FLAP RETRACTION WAS MADE ON SCHEDULE THEN THE FE PROCEEDED TO TURN ON THE R PAC. THIS PROC WAS MADE NECESSARY DUE TO A PRIOR DMI ON THE #1 GENERATOR. THE CLB PROCEEDED NORMALLY WITH SLIGHT DEVS FOR WX IN THE CENTRAL FLORIDA AREA. SHORTLY AFTER THE ACFT HAD CLRED THE WX; THE FE INFORMED US THAT THERE WAS A PROB WITH THE FUEL (12000 FT). THE WING TANKS WERE APPROX 5000 LBS LOW (PER SIDE). AFTER CHKING THE FUEL DUMP PANEL; CIRCUIT BREAKERS; AND THE QUANTITY GAUGES AGAIN; IT WAS DETERMINED THAT WE WERE NOT LOSING FUEL. THE CAPT ASKED FOR THE GALLONS UPLIFTED; THE MATH WAS CHKED; AND A CALL WAS MADE TO THE COMPANY. THE DECISION WAS MADE TO RETURN TO SFB AND FLT RETURNED TO THE GATE WITHOUT FURTHER INCIDENCE. UPON RETURNING TO THE GATE; THE FUEL SLIP WAS EXAMINED AGAIN AND IT WAS FOUND TO HAVE BEEN FROM A PREVIOUS FLT. SUPPLEMENTAL INFO FROM ACN 523463: DURING CLB; I NOTICED THAT FUEL GAUGES #1 AND #3 WERE AT 5000 LBS EACH. INFORMED CAPT THAT WE HAD A FUEL PROB. WE CONTACTED OUR COMPANY VIA COMMERCIAL RADIO AND ASKED FOR ADVICE ON WHAT TO DO. THEY TOLD US TO RETURN TO OUR DEP ARPT. WE THOUGHT WE HAD A GAUGE PROB OR THAT WE WERE LOSING FUEL. WHEN WE GOT BACK TO THE ARPT; WE REALIZED THAT I HAD THE WRONG FUEL SLIP FOR OUR UPLIFT AND THAT WE HAD TAKEN OFF 9000 LBS LESS THAN WE NEEDED. CONTRIBUTING FACTORS: 1) DELAY DUE TO ACFT SWAP. 2) DEFERRALS WITH A GENERATOR INOP- AND AUTOPLT INOP. 3) INCORRECT FUEL SLIP ON THE ACFT. 4) ACFT INCORRECTLY PRE-FUELED PER PROCS. I BELIEVE THAT I ALLOWED MYSELF TO FEEL THE PRESSURE AND STRESS OF A LATE DEP AND MECHANICAL PROBS AND WRONG FUEL SLIP TO LEAD ME TO BELIEVE I HAD THE CORRECT FUEL. WE SUGGESTED TO OUR COMPANY THAT WE INCLUDE FUEL TANK VERIFICATION ON OUR WT AND BAL FORM AND HAVE THE FO VERIFY THE FUEL AS WELL TO INCLUDE ANOTHER CREW MEMBER IN THIS PROCESS. SUPPLEMENTAL INFO FROM ACN 523464: WHILE CLBING OUT ENRTE; THE FE INFORMED ME THAT WE HAD A FUEL PROB. WE DETERMINED THAT WE WERE NOT GOING TO HAVE ENOUGH FUEL TO COMPLETE THE TRIP. CONTACTED COMPANY AND INFORMED DISPATCH WHOM RECOMMENDED A RETURN TO SFB. UPON ARR IN SFB; DISCOVERED THAT THE FUELER HAD LEFT THE ACFT ONLY PARTIALLY FUELED TO REFILL THE FUEL TRUCK. DUE TO A LAST MIN ACFT SWAP; AND THE FE AND I BOTH MISREADING THE GAUGES AND ON OLD FUEL SLIP THAT WAS LEFT ON THE FE'S DESK THAT SHOWED THE PROPER UPLIFT. WE DEPARTED SFB APPROX 10000 LBS SHORT OF FUEL.
