That's interesting, Jim. I now have tankzilla installed, because my old fuel sender would point straight up occasionally. When I still had my original sender installed, I remember I had very low fuel, less than 1/4 tank, and I drove up a steep hill & the fuel gauge dropped to empty & only then did the low fuel light flicker. I have also read somewhere, maybe in the archives, about different experiences with the low fuel light & one said that the low fuel light came on when the gauge hit empty, & he ran out of gas 30 seconds later. According to service bulletein ST-28-11/81 a different fuel sender was introduced at vin 5238. Both you & I would have this type of fuel sender, (my vin is 16822) so that wouldn't be what is causing the discrepancy. Any ideas?
