Your pump is not compatible with the supercharger pump. The pressure rates are much high for a supercharged engine. Your normally aspirated engine requires less fuel, thus, a smaller capacity pump.
You may want to check under the rear seat to see if there is an access hatch to remove the fuel pump/sending assembly. Then dropping the tank would not be an issue.
I would not suggest putting a used fuel pump into any vehicle. A new one should be available for 50-100 dollars. Also replace the strainer at the base of the fuel pump when you replace the pump.

The fuel tank must be removed to replace the fuel pump, be care when changing the pump, a little spark from a tool and you can be instant toast.

If you have 3 strong friends it is easier to pull the box off the truck-20 minutes- can do with full tank. Don't forget to unhook the taillight wires and the fuel filler neck. When you go back on make sure the tube for the spare tire winch is positioned correctly. Have saw horses to set the box on behind the truck. Be sure to buy the complete fuel pump module. If you buy just the pump you will be doing this multiple times. Also, if your fuel guage does'nt work, put a new fuel sender in at the same time (if the module does'nt come with it).

Testimonial: "Thanks this will definitely help me to do the Job right the first time."
You cannot draw fuel through the old pump. If you want to convert to external pump, you will have to install a new take-up in the tank.
For passkey II, the procedure at http://vats.likeabigdog.com/ works to bypass the ignition switch, but it will not bypass the whole system.
Please let me know if you have more questions.
