has anyone ever had any issues with their fuel gauge? my fuel gauge currently reads about 1/8th tank more than what i really have. i know it has to do with resistance and amps. i just forget exactly how to check everything. it actually annoyes me as i would like my gauge to work correctly. i should mention that, the fuel pump is factory, the tank has only been lowered once to install rear shackles, but nothing electrical was disconnected.
