I have a question for the forum relating to the fuel gauge for my 40 Dodge D-14 Business Coupe. I have been on a mission to fix the non-working fuel gauge system. I've replaced the sending unit, new wires from front to back and a NOS gauge. The original gauge has this removable card like piece that had three holes that line up with the studs on the back of the gauge and has very small copper wires that wrap around the entire piece. The gauge will not function without it, but it is somewhat deteriorated. Does anyone know what this piece is called or part number? Can it be replaced?
I've also followed the instructions in the shop manual to calibrate the new gauge, but the gauge will not read pass 1/2 tank even with the right arm moved all the way to its maximum point? could the above piece cause the gauge not to operate properly?
The photos attached are the piece in question.
Thanks in advance for information related to my questions.
