TEMPERATURE AND GAS GAUGE NOT WORKING-HELP

RedFish thanks for the suggestions, interestingly the first thing that I did was change the fuel sending unit and you are right the float was full of fuel, however the new unit is not sending the correct fuel level to the gauge. I ordered a NOS sending unit but is it possible that they and not balanced to the same ohms or is there another reason that the gauge shows 1/4 tank of gas when I know there is 3/4 or more fuel in the tank?
