I replaced all of my gauges in my car and went with the autometer ultra lite. But i am having a problem with the fuel level. I ordered the 0-90 ohm and the thing reads full all of the time and i mean pegged past full. The original word before and i have tested the ohms value and it never reads 0-90 so i have no idea what is a matter. I dropped the tank and took the sending unit out and moved it manually and still the same on the gauge. just don't know what to think?
