the fuel tank is easy enough to remove just make sure that you empty it as much as you can before doing so and make sure that the car is raised enough for you to withdraw the tank from underneath the car. make sure you disconnect the filler and breather pipes inside the car (behind the rear passenger doorcard/panel) before you go underneath and make note of the sender wiring connections before pulling them off. the nuts that hold the tank on should come off easy enough i have never had any trouble, make sure you clean the threads up and give them a good lube up before reassembly also while the tanks off get the underseal out and do the now visible underside.
