Re: Fuel tank sending unit

[Dan McCormack <mcwheels@xxxxxxxxxxxxxx>]

That's normal Bill. The fuel gauge (along with the oil and temp gauges if 
you have them) run on 5 volts. The 5 volts comes out of the voltage limiter 
which works by pulsing the 12 volts on and off. Are you sure that the new 
sending unit has a good ground?
