    As said above, drive it until it is almost out of gas. You can leave a gas can in the bed in case you run out of gas doing this. I think all you need is a 15mm socket, 8mm socket or flathead, an extension, ratchet or impact, jackstand, and a jack with a 2x4. They are VERY easy with an almost empty tank. Jack the left side up and place a jackstand on the rail where it won't interfere with the tank removal. You can take off the left rear wheel, but you don't always have to. The lines unclip by hand, just be gentle and don't break the plastic. I wouldn't rush to replace the fuel pump just because it is old(160k isn't that old). The replacement pump is probably going to be made in China junk that may or may not last very long. I would just replace the sending unit if that is the problem. The stepper motors in the cluster have a lot of issues in the 03-07 trucks. I have replaced quite a few.
