Well, I have been having a few fuel gauge issues in my 05 Mustang GT, every time it gets under a quarter tank, it seems that it has a chance to stop working. I never had this problem before, then again, I hardly ever let it get passed a quarter tank. It also seems that it could be something lose, since when I go around the corner and the rear end gets loose, it will sometimes start working if its not working, and will sometimes stop working if it is working. I am not sure what it could be, so any info on what to check would be nice.
I also installed a premium cluster into my car, and everything is working currently, but never had this issue with my old cluster, but like I said beforehand, I hardly ever let it get under a quarter of a tank so I either never noticed it, or it never happened. I don't think it is cluster since both gauge and the electronic part of it stops working (0 kms to empty).
