Relieve fuel pressure by pressing opening the schrader valve (use a cloth so it soaks up the gasoline).

Blow any dirt/debris from the fuel line to fuel rail connections. Using quick-disconnect tool remove the fuel lines. I cover the ends to prevent excess fuel from running out and debris from getting in. Set aside.

Remove fuel injector harnesses. Squeeze the metal clips and pull up.

Remove four bolts holding fuel rail to intake manifold.

Clean/blow out any dirt that has accumulated in the fuel injector bosses (don't wan that stuff falling in!). Gently pry up on the fuel rail. If it's never been removed the fuel injectors will likely be very snug and will require some fiddling. You may want/need to install new fuel injector O-rings, at the very least lubricate them before reinstalling.
