My wife has a 01 bonneville that the fuel gauge doesn't work right in. It'll read right till it gets to between a 1/2 and 3/4 of a tank then it will randomly read full or empty or somewhere in between. I don't want to have to change the fuel pump just to fix this but she really wants it fixed. Please tell me there is something easy to fix so she stops *****ing about having to reset the odometer at each fill up.
