Removing a 2002 Malibu fuel rail 3.1?

first of all relieve fuel pressure at schrader valve on to back of engine, undo all wires and hoses, take off intake on top pf engine, remove the 4 bolts holding injectors on, remove electrical connectors from injectors, remove inlet line to fuel rail. Do not loose or drop O ring from fuel inlet line. just did my intake gaskets on my 3.1 that's how I know, I dropped my O ring and had to by another cause the fuel was pouring out!!
