Fuel gauge
My fuel gauge shows a full tank at 3/4, a 3/4 at half, and anything less it just pegs 0. Yet, my low fuel light works...
Any ideas on fixing the gauge accuracy? I use this as a DD so it's kinda nice not to have to rely on setting the trip.

The fuel level sensor (for the gauge) is a potentiometer linked to a float in the tank. Worn or dirty contacts change the relationship between fuel level and voltage. Or, as in your case, there is a dead spot and below that level, there is no signal at all. You may be able to bring it back to life by removing the fuel pump assembly and cleaning the sending unit. More likely, you live with it or replace the sending unit.
The warning light is a separate float switch, which is why the light can work even when the lower half of the fuel gauge does not. Can also be the other way around.

removed the parts and cleaned them-- no change. Can you buy just the sending unit or is it a whole new assembly? I know just the pump runs about $150.
thanks for the help guys.
