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.

When the key is off the gauge drops slowly and I found I had a kid help me one time and he did not tighten the screw to the gauge that the wire attaches to. My tank is 7/8 full now so i think it is working fine. Thanks for all the help.
