I had mine done some time ago and all was well. It was coming on with 3 or so gallons everytime. Now, not so much. I let it go this time to see how low it would be before the warning came on. Nothing, nada. I knew I was very close to running out, and sure enough, when I filled up it took almost 17 gallons and the gauge was at exactly 1/8. Not a big deal if you are paying attention, but it could get some people into trouble. I am going to keep my eye on it, and I guess go back to filling up at 1/4 tank.
