My sender is bad - I pulled it and tested the float.
It ranges from 0-57 ohms. Now, it reads 3/4 as a full tank. Will the gauge still work properly, just on a different scale?
Also, when filling the tank, gasoline will bubble out the filler tube and spill down the truck instead of kicking off the dispenser nozzle. I assume that there is something wrong with the venting of the gas tank. Is there a common problem I can look at? Will I have to drop the tank to troubleshoot this?
