Re: fuel guage reading funny?
The sending unit on our year trucks sends a signal to the dash unit from 0 ohms to 90 ohms, (0=empty, 90 = full). I would suggest checking your sending unit to see what ohm range it is has. You may have a bad unit or the ground could be acting up. I don't know what ohm readings the 84 is supposed to have.
