Why? Is the trunk too spacious for you as-is?
I would strongly recommend that you replace the tank if it's leaking, dented, or whatever. If the tank is good, I think you should leave it alone. Check your local laws to see if that is even legal. I'm fairly sure that the law here states that there must be a metal frame between the passenger compartment and the fuel tank. If you do it you need to have the fittings for the pressure line, return line, evap line, and fuel tank pressure sensor if equipped. There
may be a problem with the EVAP system (if equipped w/ pressure sensor) if the fuel cell is not the exact same size. The PCM monitors the fuel tank pressure while the purge solenoid is commanded on and watches the pressure drop over "X" seconds. Too big a tank will probbly cause a "leak" code to set if there is enough difference to change the pressure drop. Good luck if you try it.
