After survey flts in ca and nv returning cross country to east coast base of operations, departed from goodland, ks, (gld) original destination (refueling stop) was ft wayne, in. Good VFR WX along route, 40-45 KT tailwinds, and a calculated fuel endurance of 5+30 led me to change fueling stop to erie, PA. Estimated 30 min reserve upon arrival. Endurance calculation was based on time it took to use 1/2 of fuel in main tanks based on fuel gauges. I felt this was conservative since it included startup, taxi, runup, takeoff and climb. During descent, approximately 25 NM west of eri, over lake erie, became apparent that I had less fuel remaining than anticipated. Shortly thereafter left engine quit. Switched to nearby empty auxiliary tank, turned south towards lakeshore, and declared fuel emergency. Controller provided vector and distance to ashtabula county airport (7g2). Tracked directly to field using LORAN and landed uneventfully. Total flight time 4:57. Possible factors: poor judgement, lack of common sense, failure to back up endurance figure with calculation based on fuel flow and fuel available, occasionally erratic indications of left fuel gauge, over reliance on supposed accuracy of capacitance type fuel gauge, parallax error in reading overhead fuel gauges, failure of fuel low level warning system, get homeitis -- trying to stretch it, fatigue -- 2 days of early starts and long hours.

Title: GA SMT FUEL EXHAUSTION AND DIVERSION TO ALTERNATE AFTER DECLARING FUEL EMER.
Narrative: AFTER SURVEY FLTS IN CA AND NV RETURNING XCOUNTRY TO E COAST BASE OF OPS, DEPARTED FROM GOODLAND, KS, (GLD) ORIGINAL DEST (REFUELING STOP) WAS FT WAYNE, IN. GOOD VFR WX ALONG RTE, 40-45 KT TAILWINDS, AND A CALCULATED FUEL ENDURANCE OF 5+30 LED ME TO CHANGE FUELING STOP TO ERIE, PA. ESTIMATED 30 MIN RESERVE UPON ARR. ENDURANCE CALCULATION WAS BASED ON TIME IT TOOK TO USE 1/2 OF FUEL IN MAIN TANKS BASED ON FUEL GAUGES. I FELT THIS WAS CONSERVATIVE SINCE IT INCLUDED STARTUP, TAXI, RUNUP, TKOF AND CLB. DURING DSCNT, APPROX 25 NM W OF ERI, OVER LAKE ERIE, BECAME APPARENT THAT I HAD LESS FUEL REMAINING THAN ANTICIPATED. SHORTLY THEREAFTER L ENG QUIT. SWITCHED TO NEARBY EMPTY AUX TANK, TURNED S TOWARDS LAKESHORE, AND DECLARED FUEL EMER. CTLR PROVIDED VECTOR AND DISTANCE TO ASHTABULA COUNTY ARPT (7G2). TRACKED DIRECTLY TO FIELD USING LORAN AND LANDED UNEVENTFULLY. TOTAL FLT TIME 4:57. POSSIBLE FACTORS: POOR JUDGEMENT, LACK OF COMMON SENSE, FAILURE TO BACK UP ENDURANCE FIGURE WITH CALCULATION BASED ON FUEL FLOW AND FUEL AVAILABLE, OCCASIONALLY ERRATIC INDICATIONS OF L FUEL GAUGE, OVER RELIANCE ON SUPPOSED ACCURACY OF CAPACITANCE TYPE FUEL GAUGE, PARALLAX ERROR IN READING OVERHEAD FUEL GAUGES, FAILURE OF FUEL LOW LEVEL WARNING SYS, GET HOMEITIS -- TRYING TO STRETCH IT, FATIGUE -- 2 DAYS OF EARLY STARTS AND LONG HRS.
