1987 5.8L Carb. Fuel guages don't work
I recently bought a 1987 F150 XLT Lariat extended cab with a carburated 5.8L V8.
Neither the front or rear fuel guages function correctly, so I never know exactly how much gas I have.
I am guessing that the floats in the gas tanks need to be replaced. Is this correct?
Has anyone had to do this on one of these?

Could be a failure of both gauges, or a problem with the switch controlling the operation between the tanks, or a wiring problem between the switch and the gauge.
Suggest to get ahold of a shop manual with electrical schematics in efforts to save unnecessary efforts and parts replacements.

The guages work, they just do not give a correct reading. The switch for front/rear tank works also.
When I fill either tank up the needle goes WAY past "F" for full. Then as the fuel is burned out of the tank (around 1/4-1/2 full) the needle will bounce between 1/4 & 3/4 until it suddenly bottoms out at "E". Then you'd better gas up quick cause there's not much left in that tank.
