yea I had that problem too. when I gassed up to a full tank, it only said I had 3/4. apparently the shop installed it wrong and had to do it again. sometimes if goes all the way to empty, then back to where it really is. its really annoying.Hey everyone, this is my first post on the site. I just got an xterra and found that the fuel gauge only goes up halfway. Thought it might be a problem with sending unit. So I just finished replacing it and noticed that there is a box around the fuel pump that seems to be interfering with the wiper travel on the sending unit. It's making it difficult to remove and install the unit as well, but i managed to fit the new one in. Has anyone else had this problem or know what to do about it?
