You'll want safety glasses, then blow down the engine good with either a shop vac or air compressor. Make sure you have a cool or cold engine, release fuel pressure, remove fuel pump fuse, an have shop rags and container to catch any fuel. Before ever installing the fuel rails lobe the O-rings and injector o-rings(replace if damaged) with fresh engine oil, and don't over tighted the fuel rail fittings, otherwise you'll create a leak either now or later. Finally varify there's no fuel leaks before running the engine for more then a few seconds.

Oh, and make sure you have the fuel line disconnect tool, and that your fuel rail fitting and hoses have no debris in them. I usually just spray carb cleaner through them.

NO cutting! Use a fuel rail hardline disconnect tool where the soft line connects to the factory rail. You might also have to go back further and disconnect the softline where it connects to the hardline on the firewall. Sorry I don't have a GTO so I can't give you any more info, especially since I can't really find any good info; anyway good luck.
