should be a 34 or 35 gallon tank, how long do you run it after the low fuel light comes on? mine usually comes on when i have a about 6 gallons left at least that's what i'm assuming becuase I try to fill it up asap when the light comes on and it usually takes anywhere from 29 gallons to 31 depending on when i can fuel up

And to elaborate on this. The sending units on theese trucks have been known to be fickle as all getout. Gary from the TDR Did one of his "Anatomy of" threads that sums it up pretty well as to what Is going on when it is doing what it is supposed to be doing. ... and doesn't.
The floats are also another issue as they just simply dissintergrate (Ugh spelling) in the tank over time.

mine does the exact same thing, shows it being lower then it trully is, max i can get in mine is between 25-27 if i fill up on the 1/4 mark every time, i have never and will never let it run low enough to trip the light. just not something i like to do. anyway, when i dropped my tank to put the draw straw in i noticed that the float even at empty stayed bout 2-3 inches above the bottom of the tank.
