on my '66 Coronet Wagon, the fuel gauge does the typical only show half a tank when full, I changed to a solid state limiter from RTE, and installed a new fuel gauge which states to use a solid state limiter. Now I turn the key on and the gauge runs to full, then backs off and pulses like the test light when a guy tests for current. Any ideas? is my new limiter bad? I put a new tank, new sending unit, and new fuel line in.
