First of all my 1955 ford went down the road fine and passed inspection with no problems but the fuel gauge was reading full and I put 25.00 worth of gas in it and temperature read hot but it was not over heating and the radiator felt normal not excessive hot.

JLB,



Very nice write up on the working of the fuel and temperature gauges. A little confused though, my wiring is power from ignition switch to gauge to sending unit to ground (reverse what you show in your diagram). There is only one wire going to the sending unit be it the temperature or fuel gauge sending unit.



Sorry, I can't draw a diagram as nice as yours to indicate what I'm referring to.
