Pull the inner rear fender liner on the driver's side to get to the hoses and wires. Start with a close to empty tank. I am not sure if the wiring harness on yours is the same as on the 2000s, but the little red clip just gets slid over in order to unhook the harness. You don't have to completely pull the red clip out. Make sure you have a new pump assembly gasket to use when you put the new one in. The old one can leak fumes.
If you want to do an aftermarket gas tank skid, do it now while you have the tank out since you'll have to pull the tank again to add one later.
