The fuel guage on my 2007 Ultima constantly reads full. I went to my local Toyota dealer and was told that they could "investigate the problem for me", but that would cost me $270... Just to look! Has anyone else had this problem? I am looking at tackling the job myself but would like some information from the Service Manuals on 1) how to remove the fuel tank [as the sender is mounted in the top, and I don't see any access panels in the floor] and 2) if there is some electrical test I can do before hand, so I don't waste my time pulling the tank out, just to find it is something simple, like a bad joint! By the way, a V6 Ultima gets up to 439.5km from a tank around town, after that your pushing (LITERALLY!!)
