Bought my first XJ off a friend. As I was driving away I said to myself, "Sweet, full tank of gas". A couple days later I said "Man, this thing gets great gas mileage". A couple days layer it dies on me. No fuel pressure. "Crap, need a new fuel pump and the tank is full." Get the parts and tear into it. Remove the straps and as I'm lowering the jack I realize that the tank is empty. Can't remember if I replaced the pump or not, that may be the one sitting on my shelf. Told my buddy the story and he's like "All yeah, I forgot to tell you..."
