Well, the sender is going to be on the fuel pump assembly in the fuel tank. I have been told by others on the board that very often, the problem is the gauge itself. I heard a rumor that Ford was actually kind enough to put an access panel under the back seat to keep you from dropping the tank. Would be nice, doubt if it's true.
I have a problem where my gauge always reads past full and my low fuel light is alway on. I was advised by another member that he fixed both problems by replacing the gauge itself. I think the thread was titled "Information center grounds" or something like that.
