The other day, my car unexpectedly sputtered to a stop. The fuel gauge showed nearly half a tank and the low fuel light never came on before it happened, but as it turned out, I really had run out of gas. From looking through similar threads I get the idea that the sensor that determines the gauge position and the one that turns on the light are independent. First of all, can someone confirm this? If it's true, it's interesting that neither one seemed to be functioning.

Once I filled it up, the needle went to Full but it barely moves below that position. Right now I'm just going by mileage with knowing when to fill my tank, but I'd like to fix this somehow. It seems to me that if there are two independent sensors, then it probably isnt just that the float is stuck.

Just wondering if anyone can give me an answer on this one, or if there's something else I should be looking at. Thanks.
