Crazy Gas Gauge

I too am tired of fighting these crap aftermarket sending units. Mine reads Full correctly but will drop to around 1/4 tank after using about 5 gallons. From there it quickly drops to empty then I have no idea whats in it.
So I bough some phenolic sheet to cut out some blanks to reproduce the resistor for the sending unit. The original ones liked to warp and the rivits would corrode and fall off. The wire needed is Nichrome resistance wire, 36awg (.0005"). The sender uses 46" of this wire and should ohm out around 85Ω.
Wrapping the coil is going to be hard to do. My first attempt did not turn out well.
