This is the situation: I installed the indiglo gauges on my car. The temperature needle does not need to be repositioned if moved... The mph and rpm needles were adjusted to be back where they are supposed to be. The problem is the gas needle. It does not reposition itself and i want to make sure its accurate. I put it back where i thought it was... This is the question: What sets off the low fuel light? is it the position of the needle or a sensor unrelated to the needle position? THANKS
