1) If you're serious about saving fuel, you need better feedback than the fuel gauge. As others have said, get a ScanGauge or Ultragauge. With the amount of fuel your truck uses, it'll pay for itself in no time.
2) I'm skeptical anyway. My experience is: people worry way too much about acceleration technique. If you're not pulsing & gliding, accel. style will have a small impact on your overall tank mileage. FAR more important is use of the brakes (sub/ex/urban driving obviously), and it sounds like you're headed in the right direction there.
I'd suspect filling technique, whether your routes/usage is identical to the tanks you're comparing, and whether or not you've actually re-filled the tank yet (it's mostly useless to guess based on the needle!).
