Its pretty easy. Start by opening the filler door and pulling the 3 screws that hold the nozzle to the bed. Then you'll need to take the 6 bolts out that hold the tank skidplate out to drop that. Next I put a floor jack under the tank so you can drop it slowly. You'll then need to pull the 6 bolts that hold the tank in place. Once it is down a few inches you'll be able to get the fuel lines and the wireing harness unplugged and finish dropping it all the way. The only tools that you'll need are a 12mm with about 6" of extension for the skidplate and tank mounting bolts. A 17mm and a 19mm wrench for taking the highpressure fuel line off the tank. A phillips screwdriver to pull the filler tube mounting screws and the 8 fuel pump mounting screws. Also a pair of slip joint pliers to take the clamps off of the return and vent lines.
